Regatta basic & start timer - Apps on Android Market
chris1232012-01-29 07:40 UTC
After spending far too many hours rooting and unlocking my new cell
phone, next it was off to the android market. For those that race,
this looks pretty interesting.

That's complicated. I will need to study it. Did you get it? How is it?
I have BC Racer and it is good, easier to understand but lacks what I
consider the most important function which is called TURN on a Garmin GPS.
I think this new app has it.
A word of warning on using GPS to time a start. You will be early as the
GPS lags its position. In fact, you will be so early that it is probably
not useful, I am thinking 50 to 100 feet off.
There are some functions I would love to see so if anyone out there wants
to build an app, talk to me.
Basically, I want to see an app that will tell me, when I am sailing away
from the line, when I should turn around and sail back to hit the line on
time. You would have to store your speed and time to turn but then the
phone could do the rest. Then you can adjust your course to hit the line
just right. That calculation is difficult to do mentally when you sail in
a lot of current.

Nope, dont race, most on this list do, so figured I would pass it on.

That would require multiple sensor inputs to calculate all the vectors.
Not sure it can be done unless you have a completely wireless setup on all
the instruments, which is almost possible now a days.
See http://dmkyacht.com/
but they currently only support Apple. They are working on an android
solution and when I offered them dev support.....the conversation ended. So
it will be some time till it gets done. I dont code but from a previous
time know some very good ones who would have loved to tackle this project.
All in good time I guess.
There was another device that I found that takes all the data input and
transmits them via wifi but the front end was proprietary. ie: lots of
money...:)

No, it is simple. All you need is the GPS in the phone. You do a practice
run. Go to the line, turn and go away. Press the button right at where
you want to turn back to the line, turn the boat and build up speed to the
line. Press the button again when you get to the line. This practice run
should be approximately what you plan on doing. In use, you start the app
as you start your run away from the line. Ideally, you are at the same
distance from the line with the same amount of time left as at practice at
which point the app tells you to turn. If you are early or late, it can
make the calculation of what the difference in time to turn is. The
calculation involves adding or subtracting time based on your practice
speed at the line and using that to determine when you need to start your
turn. Simple calculation... for a computer. If you are late starting your
run away from the line, the program has you start your turn a little closer
to the line than in your practice run. Distance based on speed at line
during practice and time left.
It is a perfect calculation for a computer and I am surprised nobody has
coded it up. Everyone just codes up how long it will take you to get to
the line at your current speed. What it is telling you is that you are
either early or late. Better to make an app that tells you how to be on
time. I think this would get you much closer to on time than the normal
app which has a 50 foot error in it. In what I am suggesting, most of the
errors cancel out.
Maybe I will have to code it up myself. I will need a new project as soon
as the Light List Waypoint editor is documented.

I often wonder why nobody programs these kind of functions. Maybe it is
because I have a big heavy boat that takes time to get up to speed and
knowing I am a few seconds early means I need to slow the boat down and
will be slow at the start is different than the dingy racers who can sit
there and accelerate in just few seconds. The problem is that the effort
for writing such a program when you have to come up on the learning curve
is large and the market is probably small.
I just spent about a man week on this set of pages to find waypoints and
create routes. It was fun and all that but not clear how many people are
going to be interested. I think I have 4 responses off this list and I
appreciate each one, but that also means most people don't care. So doing
another sail race application would have to be a labor of love.
By the way, L-36.com gets about 30,000 page views a month. It also happens
to have about 30,000 pages on the site! Love that auto generated stuff. I
just added over 500 pages with the waypoint stuff alone. But that is not
enough to make more than beer money.

Allen, Their is software available named Expedition Tactical/Routing Software. It takes data from your Okham or other instruments and your GPS and displays it on your laptop. It actually creates the entire start line between the two marks. Be ready to spend $1,350 for it, but many in the Great Lakes have it for the long distance races, including me.

Timm was kind enough to run Expedition before one of the Master Mariners
races. It gave me a routing around the marks here in the bay. However, it
did not do that good a job with the current. We followed a model I put
together in Excel and won the race because of it.
It actually isn't that hard to get a start line in something. You can do
that with any GPS by asking for track error (I think that is the term) to a
route between the ends of the line. That will tell you the distance to the
line. BC Racer will tell you how long it will take you to get to the line
on the course you are on. That costs $4. But if you are using GPS and
don't do something about the errors from lag, you can do better by eye.
That said, can Expedition tell you when to turn around and head back to the
line? I think that would be the thing I want.
I think Expedition is best for long races where it is helping you find the
best winds.

That was a nice watch, one of my competitors uses it. But what were are
talking about here uses GPS so you could be just sitting in one spot
luffing and the app would tell you when to when to head to the line,
assuming that is the approach you had the app train on. The watch was for
strict timed runs back away and back at constant speed if I understood
correctly.
Let me give an example. On the Master Mariners last time we started by
running parallel to the line, which is aligned with the wind, not
perpendicular with it as is typical for a starting line. At about the
right time to the gun, we hardened up and headed to the line. We were
early so had to do little S curves to kill time. With a trained GPS app,
it would know how far you were from the line, how fast the boat would be
going at the line, and how long it takes to accelerate so it could tell you
exactly when to harden up.
I might just have to write it myself.

RE: [Cal_Boats] Regatta basic & start timer - Apps on Android Market
ti… [at] ch2m.com2012-01-30 22:16 UTC
My starting sequence in a busy race.. if the fleet is small enough manage - intimidate:
1. 5 minute practices; note sailing angles (pick landmarks and courses) to cross, time out and back legs
2. Marshmallow Room; find weak boat(s) get close to them - weave - wobble - wiggle - bring up and down and push them away to make an open slot for your footing.
3. Foot for speed; We foot as hard as possible for max speed, while working our slot.
4. Power (trim) Genoa first; once the slot is good and we can sail across, harden the Genoa and bring up the course from foot to point.
5. Then trim the Main; once you need to lock the course
6. Begin watching the first tackers.
If you pick an busy or crowed end, then no program could work, as you spend all efforts tacking and dodging - fiddling with a computer could not happen - unless you have a dedicated boat to boat tactical officer. (we do on important races)
I usually decide to go to the lonely side of the line for clear air - longer races - but when tangling up for short courses, use the 6 steps above, listen to my countdown timers call off the time, and my bowman calling off last second avoidance tactics and lengths to the line.

That was a nice watch, one of my competitors uses it. But what were are talking about here uses GPS so you could be just sitting in one spot luffing and the app would tell you when to when to head to the line, assuming that is the approach you had the app train on. The watch was for strict timed runs back away and back at constant speed if I understood correctly.
Let me give an example. On the Master Mariners last time we started by running parallel to the line, which is aligned with the wind, not perpendicular with it as is typical for a starting line. At about the right time to the gun, we hardened up and headed to the line. We were early so had to do little S curves to kill time. With a trained GPS app, it would know how far you were from the line, how fast the boat would be going at the line, and how long it takes to accelerate so it could tell you exactly when to harden up.

Timm was kind enough to run Expedition before one of the Master Mariners races. It gave me a routing around the marks here in the bay. However, it did not do that good a job with the current. We followed a model I put together in Excel and won the race because of it.
It actually isn't that hard to get a start line in something. You can do that with any GPS by asking for track error (I think that is the term) to a route between the ends of the line. That will tell you the distance to the line. BC Racer will tell you how long it will take you to get to the line on the course you are on. That costs $4. But if you are using GPS and don't do something about the errors from lag, you can do better by eye.
That said, can Expedition tell you when to turn around and head back to the line? I think that would be the thing I want.
I think Expedition is best for long races where it is helping you find the best winds.

No, it is simple. All you need is the GPS in the phone. You do a practice run. Go to the line, turn and go away. Press the button right at where you want to turn back to the line, turn the boat and build up speed to the line. Press the button again when you get to the line. This practice run should be approximately what you plan on doing. In use, you start the app as you start your run away from the line. Ideally, you are at the same distance from the line with the same amount of time left as at practice at which point the app tells you to turn. If you are early or late, it can make the calculation of what the difference in time to turn is. The calculation involves adding or subtracting time based on your practice speed at the line and using that to determine when you need to start your turn. Simple calculation... for a computer. If you are late starting your run away from the line, the program has you start your turn a little closer to the line than in your practice run. Distance based on speed at line during practice and time left.
It is a perfect calculation for a computer and I am surprised nobody has coded it up. Everyone just codes up how long it will take you to get to the line at your current speed. What it is telling you is that you are either early or late. Better to make an app that tells you how to be on time. I think this would get you much closer to on time than the normal app which has a 50 foot error in it. In what I am suggesting, most of the errors cancel out.

Hi Timm,
I don't think there is any degree that the line can be off that makes the
"favored" end of the line better than being in clear air. As evidence of
that, in the Master Mariners the line is parallel to the wind instead of
perpendicular. You can't have a more heavily favored end. We were at the
favored end in traffic one year and another L-36 was down the line and did
much better. I also did some calculations assuming boat speeds for traffic
and added distance from being at the non favored end and clear air was the
winner.
The point of the app would be to tell you when to begin your start sequence
knowing where you are as well as how much time remains. Right now you are
starting knowing only how much time remains. It has to be better. You are
just pointing out that it isn't a simple thing. I agree, this would only
work if your tactician wasn't also your grinder.
I am not committed to doing this app but if I do it would be on Android. I
hate Apple.

I AGREE about open-clean air for the majority of races... The standing exception(s) may be match and one design fleets, particularly on short courses.
Perhaps match racers don't really care about the line, except as an obstacle to use against the competition, and similarly the short races are simply about initial position, as there are no real passing lanes.
If you can force your way into open air, on the favored end, then you can completely control and gas the fleet.
I do not race on the Columbia, generally. The courses here are so short, that with few exceptions, the boat that wins the start wins the race.
I am Apple ambivalent - never owned one, yet have a curious admiration from a distance. I guess they have great marketing - I've heard from sources that technology wise they are inferior to Droids - but have a sweeter presentation.
One nice feature of our local Cal 20 fleet. NO ELECTRONICS allowed.
I'm meeting - being interviewed by Garmin Marine HQ tomorrow - about the future of their instruments and the needs and shortcomings of the casual racer. I did beta testing on their newest line of stuff. I'll bring up some of your thoughts.

Hi Timm,
I don't think there is any degree that the line can be off that makes the "favored" end of the line better than being in clear air. As evidence of that, in the Master Mariners the line is parallel to the wind instead of perpendicular. You can't have a more heavily favored end. We were at the favored end in traffic one year and another L-36 was down the line and did much better. I also did some calculations assuming boat speeds for traffic and added distance from being at the non favored end and clear air was the winner.
The point of the app would be to tell you when to begin your start sequence knowing where you are as well as how much time remains. Right now you are starting knowing only how much time remains. It has to be better. You are just pointing out that it isn't a simple thing. I agree, this would only work if your tactician wasn't also your grinder.
I am not committed to doing this app but if I do it would be on Android. I hate Apple.

When I originally bought mine GPS was a military thing only, not to mention
that I sailed in the Niagara River (3 miles from the top of the Falls) where
we had almost 2 kts of current. In these conditions the watch would have
worked better than GPS. However, in all cases a.) the wind and boat speed
varies and b) there are other boats. I found that it all came down to
skipper and crew being in sync.

That was a nice watch, one of my competitors uses it. But what were are
talking about here uses GPS so you could be just sitting in one spot luffing
and the app would tell you when to when to head to the line, assuming that
is the approach you had the app train on. The watch was for strict timed
runs back away and back at constant speed if I understood correctly.
Let me give an example. On the Master Mariners last time we started by
running parallel to the line, which is aligned with the wind, not
perpendicular with it as is typical for a starting line. At about the right
time to the gun, we hardened up and headed to the line. We were early so
had to do little S curves to kill time. With a trained GPS app, it would
know how far you were from the line, how fast the boat would be going at the
line, and how long it takes to accelerate so it could tell you exactly when
to harden up.
I might just have to write it myself.

Timm was kind enough to run Expedition before one of the Master Mariners
races. It gave me a routing around the marks here in the bay. However, it
did not do that good a job with the current. We followed a model I put
together in Excel and won the race because of it.
It actually isn't that hard to get a start line in something. You can do
that with any GPS by asking for track error (I think that is the term) to a
route between the ends of the line. That will tell you the distance to the
line. BC Racer will tell you how long it will take you to get to the line
on the course you are on. That costs $4. But if you are using GPS and
don't do something about the errors from lag, you can do better by eye.
That said, can Expedition tell you when to turn around and head back to the
line? I think that would be the thing I want.
I think Expedition is best for long races where it is helping you find the
best winds.

I often wonder why nobody programs these kind of functions. Maybe it is
because I have a big heavy boat that takes time to get up to speed and
knowing I am a few seconds early means I need to slow the boat down and will
be slow at the start is different than the dingy racers who can sit there
and accelerate in just few seconds. The problem is that the effort for
writing such a program when you have to come up on the learning curve is
large and the market is probably small.
I just spent about a man week on this set of pages to find waypoints and
create routes. It was fun and all that but not clear how many people are
going to be interested. I think I have 4 responses off this list and I
appreciate each one, but that also means most people don't care. So doing
another sail race application would have to be a labor of love.
By the way, L-36.com gets about 30,000 page views a month. It also happens
to have about 30,000 pages on the site! Love that auto generated stuff. I
just added over 500 pages with the waypoint stuff alone. But that is not
enough to make more than beer money.

No, it is simple. All you need is the GPS in the phone. You do a practice
run. Go to the line, turn and go away. Press the button right at where you
want to turn back to the line, turn the boat and build up speed to the line.
Press the button again when you get to the line. This practice run should
be approximately what you plan on doing. In use, you start the app as you
start your run away from the line. Ideally, you are at the same distance
from the line with the same amount of time left as at practice at which
point the app tells you to turn. If you are early or late, it can make the
calculation of what the difference in time to turn is. The calculation
involves adding or subtracting time based on your practice speed at the line
and using that to determine when you need to start your turn. Simple
calculation... for a computer. If you are late starting your run away from
the line, the program has you start your turn a little closer to the line
than in your practice run. Distance based on speed at line during practice
and time left.
It is a perfect calculation for a computer and I am surprised nobody has
coded it up. Everyone just codes up how long it will take you to get to the
line at your current speed. What it is telling you is that you are either
early or late. Better to make an app that tells you how to be on time. I
think this would get you much closer to on time than the normal app which
has a 50 foot error in it. In what I am suggesting, most of the errors
cancel out.
Maybe I will have to code it up myself. I will need a new project as soon
as the Light List Waypoint editor is documented.

Wow, I completely disagree. Consider the case with a boat going 6 knots in
2 knots of current. Sail away from the line at 8 knots for 1 minute then
return to the line at 4 knots and think you are going to get there in 1
minute? That is the algorithm on the watch being discussed assuming we are
talking about the same watch.
On the other hand, if your GPS app knows you are going to be traveling 4
knots on your return trip and you head away from the line at 8 knots, at
about 40 seconds it is going to tell you to turn around and go back giving
you 80 seconds to get there. This assumes 0 time to turn and instant
acceleration.
The last race we were in had 4 knots of current. We stayed along the shore
out of both the wind and the current. We caught all but 2 boats of the
faster fleet that started 10 minutes ahead of us. Current is very
important in SF Bay. This was in a T-10, not Papoose for full disclosure.

Getting a good start isn't all that hard. What works for me is a very sophisticated devise that is attached to ones wrist. It is called a TIMEX....with Chrono. Find yourself along the start-line during the 5 or 10 minute warning, sail away with your timer set while on a coarse that will give you an optimum return to the line. What electronics can not do is assess the actions of the other boats and often finding the best position at the start will require some quick un calculated manuvers.
Too many electronics take the attention away from sailing fast in the right direction.

Yes, the best pre-start "computer" is between your ears. No electronic device could come close to adjusting for all the things you sometimes have to think about at a starting line.

Regatta basic & start timer
Michael D2012-02-03 14:06 UTC
All,
A starting watch/timer is invaluable. We use a Ronstan ClearStart model. With buoy racing, the race is often won at the start. Racing in a class of boats with a wide range of handicap ratings, the general rule of thumb is go for "clear air" and away from larger/faster competitors "dirty air".
On Magic, we typically use the Vanderbilt Start. Google it. As "weekend warriors" with rotating crew, it has proven to be a consistent winner for us to be at the line at 0:00.
Assign a crew member to operate the watch and announce time remaining till start. Be at or near the start line at the 5-minute signal. The timer, tactician, and helmsman need close coordination. Grinders, railmeat, and trimmers should preload leward winches/sheets to be ready at all times. Lazy sheets should not be underfoot in the cockpit.

Getting a good start isn't all that hard. What
works for me is a very sophisticated devise that is attached to ones wrist. It
is called a TIMEX....with Chrono. Find yourself along the start-line during the
5 or 10 minute warning, sail away with your timer set while on a coarse
that will give you an optimum return to the line. What electronics can not do is
assess the actions of the other boats and often finding the best position
at the start will require some quick un calculated manuvers.
Too many electronics take the attention away from
sailing fast in the right direction.

Hull to Deck Joint Leaks
Michael D2012-02-03 15:58 UTC
My Adminral is getting tired of the leaks: therefore I am.
Magic has a teak rub rail with SS cap. A PO attached the teak to the hull with 5200, so removal will be destructive. What will I find under the teak? I assume the Cal 2-27 joint is an "outward flange" as shown in the attached files. Can anyone confirm this? I seem to remember at least one other Cal owner going through this on some old email threads...
I know it'll take a boat buck or more, but I want a long term fix/repair; not a temporary "patch".
A Happy Wife is a Happy Life...
Thanks!

Re: [Cal_Boats] Regatta basic & start timer
Allen Edwards2012-02-03 16:00 UTC
Michael, I also use a clear start watch. I also try for clear air. I have
done calculations to try and figure out what the relative advantages of
"clear air", "favored end"., and "more wind" are and "favored end", which
is what most people read about and where most of the boats are, is at the
bottom of the list unless the committee isn't at all good at setting the
line. I usually start away from the other boats as a result, typically at
the pin end with the rest of the fleet at the committee boat. I am usually
the first or second boat at the first mark and considering that most of the
fleet owes me time, as much as 68 seconds a mile, that isn't bad.
The Vanderbilt start is based on the principal that a boat will go the same
speed on a run at 135 degrees to the wind as it will on a beat at 45
degrees to the wind. Therefore, if you know how long it takes you to turn
you and subtract that from the time you begin your start sequence (at the
line and heading away from it) then allow half the remaining time for your
return trip, you will be at the line when the gun goes off.
However, this doesn't work if you sail in current, or if you can't get to
the right place to start the sequence, or if you want to approach the line
on a reach, or...
The app I am proposing is just a way to do a timed approach without having
to time the thing with the run. If you know where you are, and you know
how long it will take you to get back to the line from that distance, you
can time it to be there on time. If you want to allow for some extra time
because of traffic, start your turn early, there can be a countdown on the
app.
Personally I would like an app like this. I see from the replies that most
people do not and that certainly removes motivation for me to write it.
Maybe I don't need it. I typically win the start without it, typically
win the race, and have won our summer series for the last couple of years.
I won the Master Mariners by 10 minutes last year so maybe I shouldn't
even worry about the start. On the MM, I went for clear air, and was a
football field away from all the other boats at the start. That particular
starting line is not set perpendicular to the wind so a Vanderbilt start
would be impossible. We did our timed run by timing by eye where we should
be and timing how long it would take us to get to the line from there. We
did it the day before. How nice it would have been to be able to calibrate
that same day in the actual wind we were racing in. You would not even
need to calibrate at the starting line, just in the same wind at the same
approach angle.
But whatever works for you. Best of luck on the race course.

RE: [Cal_Boats] Hull to Deck Joint Leaks [2 Attachments]
Husar, Charlie [USA] (ASE)2012-02-03 20:17 UTC
Michael, I think your answer is “none of the above”. I’ve been waiting years to spring this briefing on somebody. The picture of the sawed off cross section on your boat would indicate that the attached deck/hull and rub rail design applies. Seals Spars has the “gunnel rubber” (as do others). I can convert the “briefing to JPGs if needed.
Cheers

My Adminral is getting tired of the leaks: therefore I am.
Magic has a teak rub rail with SS cap. A PO attached the teak to the hull with 5200, so removal will be destructive. What will I find under the teak? I assume the Cal 2-27 joint is an "outward flange" as shown in the attached files. Can anyone confirm this? I seem to remember at least one other Cal owner going through this on some old email threads...
I know it'll take a boat buck or more, but I want a long term fix/repair; not a temporary "patch".

Subject: [Cal_Boats] Regatta basic & start timer
All,
A starting watch/timer is invaluable. We use a Ronstan ClearStart model. With buoy racing, the race is often won at the start. Racing in a class of boats with a wide range of handicap ratings, the general rule of thumb is go for "clear air" and away from larger/faster competitors "dirty air".
On Magic, we typically use the Vanderbilt Start. Google it. As "weekend warriors" with rotating crew, it has proven to be a consistent winner for us to be at the line at 0:00.
Assign a crew member to operate the watch and announce time remaining till start. Be at or near the start line at the 5-minute signal. The timer, tactician, and helmsman need close coordination. Grinders, railmeat, and trimmers should preload leward winches/sheets to be ready at all times. Lazy sheets should not be underfoot in the cockpit.

Getting a good start isn't all that hard. What works for me is a very sophisticated devise that is attached to ones wrist. It is called a TIMEX....with Chrono. Find yourself along the start-line during the 5 or 10 minute warning, sail away with your timer set while on a coarse that will give you an optimum return to the line. What electronics can not do is assess the actions of the other boats and often finding the best position at the start will require some quick un calculated manuvers.
Too many electronics take the attention away from sailing fast in the right direction.

That was a nice watch, one of my competitors uses it. But what were are talking about here uses GPS so you could be just sitting in one spot luffing and the app would tell you when to when to head to the line, assuming that is the approach you had the app train on. The watch was for strict timed runs back away and back at constant speed if I understood correctly.
Let me give an example. On the Master Mariners last time we started by running parallel to the line, which is aligned with the wind, not perpendicular with it as is typical for a starting line. At about the right time to the gun, we hardened up and headed to the line. We were early so had to do little S curves to kill time. With a trained GPS app, it would know how far you were from the line, how fast the boat would be going at the line, and how long it takes to accelerate so it could tell you exactly when to harden up.
I might just have to write it myself.

Timm was kind enough to run Expedition before one of the Master Mariners races. It gave me a routing around the marks here in the bay. However, it did not do that good a job with the current. We followed a model I put together in Excel and won the race because of it.
It actually isn't that hard to get a start line in something. You can do that with any GPS by asking for track error (I think that is the term) to a route between the ends of the line. That will tell you the distance to the line. BC Racer will tell you how long it will take you to get to the line on the course you are on. That costs $4. But if you are using GPS and don't do something about the errors from lag, you can do better by eye.
That said, can Expedition tell you when to turn around and head back to the line? I think that would be the thing I want.
I think Expedition is best for long races where it is helping you find the best winds.

No, it is simple. All you need is the GPS in the phone. You do a practice run. Go to the line, turn and go away. Press the button right at where you want to turn back to the line, turn the boat and build up speed to the line. Press the button again when you get to the line. This practice run should be approximately what you plan on doing. In use, you start the app as you start your run away from the line.

Charlie!
Thanks for the PPT. It explains a lot. The photo of the sawed off cross section was from an Ericsson (I think), and I attached it only as an illustrative example. I kind of like the teak rub rail, so I'll probably have a new one fabricated. We have a lot of marine lumber yards/mills in our area.
At the end of the day, I figure it'll date a few boat weeks to get it repaired. I'll try to photo document the project and will make them available to anyone interested.

If you are late starting your run away from the line, the program has you start your turn a little
closer to the line than in your practice run. Distance based on speed at line during practice and time left.

RE: [Cal_Boats] Hull to Deck Joint Leaks [2 Attachments]

Michael,
On my 227 the rub rail is hard plastic that slides over the two flanges
that are on the hull and deck sections. The plastic piece is attached with
screws that go through the vertical section of the rail and in between the
two flanges. A soft vinyl piece goes into groves in the rub rail to cover
the screws and aluminum caps cover both ends of the rail. And it leaks!
The rub rail design is dumb, the resistance to breakage of the hard plastic
is near zero when it is new and much worse ten years later. The hull and
deck flanges were pop riveted together and glassed on the interior since
this interior section is or was covered by cabinetry or carpet full
inspection has not been possible but I'd bet that some of the glass has
failed or that one or more of the original screws went through it.
Other versions of the CAL 227 had the rubberry rub rail, which I had on a
CAL 25. This rail slipped over the two flanges without any flanges It is a
better seal but becomes very chalky and after a few years many people put
screws in from the bottom in order to keep it attached. A friend installed
one on a CAL 28 by first heating it to make it very pliable and then
stretching it so that when it cooled it would become very tight. This
rubrail was continuous from a stern cap on starboard to one on port.
Good luck on your project, the approach that was taken on Mariposa
http://www.mariposasailing.com/hulldeck.html is probably the only one that
would stop the leak.

Allen,
I think I understand your problem from the explanation below. A variation
of the vanderbuilt start is what I learned when I started sailing/racing.
Sail away from the line on a tack that will match boat speed on a reciprocal
course back to the starting point. 1 min. out, one minute back.
I do not have a expensive chart plotter or even one of the newer more
accurate GPS. I can set a waypoint at a spot on the earth (starting line)
and set the GPS to show me an ETA to that point. Of course it is only as
accurate as my 10 year old GPS will calculate.
And you are looking to have the GPS or Computer program to calculate the ETA
to a line on the earth rather than a specific point. (maybe a series of
points would work) I am not a computer engineer nor GPS programmer. I
would like to see if this application is available, I think it is workable,
but the science of this application is well beyond my experience.
Good luck,
John

Michael, I also use a clear start watch. I also try for clear air. I have
done calculations to try and figure out what the relative advantages of
"clear air", "favored end"., and "more wind" are and "favored end", which is
what most people read about and where most of the boats are, is at the
bottom of the list unless the committee isn't at all good at setting the
line. I usually start away from the other boats as a result, typically at
the pin end with the rest of the fleet at the committee boat. I am usually
the first or second boat at the first mark and considering that most of the
fleet owes me time, as much as 68 seconds a mile, that isn't bad.
The Vanderbilt start is based on the principal that a boat will go the same
speed on a run at 135 degrees to the wind as it will on a beat at 45 degrees
to the wind. Therefore, if you know how long it takes you to turn you and
subtract that from the time you begin your start sequence (at the line and
heading away from it) then allow half the remaining time for your return
trip, you will be at the line when the gun goes off.
However, this doesn't work if you sail in current, or if you can't get to
the right place to start the sequence, or if you want to approach the line
on a reach, or...
The app I am proposing is just a way to do a timed approach without having
to time the thing with the run. If you know where you are, and you know how
long it will take you to get back to the line from that distance, you can
time it to be there on time. If you want to allow for some extra time
because of traffic, start your turn early, there can be a countdown on the
app.
Personally I would like an app like this. I see from the replies that most
people do not and that certainly removes motivation for me to write it.
Maybe I don't need it. I typically win the start without it, typically win
the race, and have won our summer series for the last couple of years. I
won the Master Mariners by 10 minutes last year so maybe I shouldn't even
worry about the start. On the MM, I went for clear air, and was a football
field away from all the other boats at the start. That particular starting
line is not set perpendicular to the wind so a Vanderbilt start would be
impossible. We did our timed run by timing by eye where we should be and
timing how long it would take us to get to the line from there. We did it
the day before. How nice it would have been to be able to calibrate that
same day in the actual wind we were racing in. You would not even need to
calibrate at the starting line, just in the same wind at the same approach
angle.
But whatever works for you. Best of luck on the race course.

A starting watch/timer is invaluable. We use a Ronstan ClearStart model.
With buoy racing, the race is often won at the start. Racing in a class of

for "clear air" and away from larger/faster competitors "dirty air".
On Magic, we typically use the Vanderbilt Start. Google it. As "weekend
warriors" with rotating crew, it has proven to be a consistent winner for us
to be at the line at 0:00.
Assign a crew member to operate the watch and announce time remaining till
start. Be at or near the start line at the 5-minute signal. The timer,
tactician, and helmsman need close coordination. Grinders, railmeat, and
trimmers should preload leward winches/sheets to be ready at all times.
Lazy sheets should not be underfoot in the cockpit.

Getting a good start isn't all that hard. What works for me is a very
sophisticated devise that is attached to ones wrist. It is called a
TIMEX....with Chrono. Find yourself along the start-line during the 5 or 10
minute warning, sail away with your timer set while on a coarse that will
give you an optimum return to the line. What electronics can not do is
assess the actions of the other boats and often finding the best position at
the start will require some quick un calculated manuvers.
Too many electronics take the attention away from sailing fast in the right
direction.

That was a nice watch, one of my competitors uses it. But what were are
talking about here uses GPS so you could be just sitting in one spot luffing
and the app would tell you when to when to head to the line, assuming that
is the approach you had the app train on. The watch was for strict timed
runs back away and back at constant speed if I understood correctly.
Let me give an example. On the Master Mariners last time we started by
running parallel to the line, which is aligned with the wind, not
perpendicular with it as is typical for a starting line. At about the right
time to the gun, we hardened up and headed to the line. We were early so
had to do little S curves to kill time. With a trained GPS app, it would
know how far you were from the line, how fast the boat would be going at the
line, and how long it takes to accelerate so it could tell you exactly when
to harden up.
I might just have to write it myself.

Timm was kind enough to run Expedition before one of the Master Mariners
races. It gave me a routing around the marks here in the bay. However, it
did not do that good a job with the current. We followed a model I put
together in Excel and won the race because of it.
It actually isn't that hard to get a start line in something. You can do
that with any GPS by asking for track error (I think that is the term) to a
route between the ends of the line. That will tell you the distance to the
line. BC Racer will tell you how long it will take you to get to the line
on the course you are on. That costs $4. But if you are using GPS and
don't do something about the errors from lag, you can do better by eye.
That said, can Expedition tell you when to turn around and head back to the
line? I think that would be the thing I want.
I think Expedition is best for long races where it is helping you find the
best winds.

I often wonder why nobody programs these kind of functions. Maybe it is
because I have a big heavy boat that takes time to get up to speed and
knowing I am a few seconds early means I need to slow the boat down and will
be slow at the start is different than the dingy racers who can sit there
and accelerate in just few seconds. The problem is that the effort for
writing such a program when you have to come up on the learning curve is
large and the market is probably small.
I just spent about a man week on this set of pages to find waypoints and
create routes. It was fun and all that but not clear how many people are

Since I just happened to be cutting up a CAL 25, here is a shot of that deck hull joint and the area that can trap water. I did not know that any of the 27s had a hard plastic rail (probably not original?). There are now a few vinyl rails that do not chalk (as much).
John, I always use t he screws from the underside. Maybe it actually helps drain that area?

There are apps that will tell you your ETA to the point on a line you are
headed to. This will work during the return portion of the Vanderbilt
start. But as you know, by then you are already too early or too late. I
personally don't see the benefit of these programs because they are only
good for adjusting if you are early. If you are late, you are late. They
have other problems as well but even if they were perfect, if you are early
your remedy is to slow down, then you end up being on time but slow.
I write programs as you know if you visit L-36.com. I am also a retired
measurement guy. I made a career out of figuring out how to remove errors
from measurements. I also race sailboats. This combination makes this a
very interesting problem.
So, just to be clear, what I am thinking of is something that will tell you
when to start your approach to the line just as your 1 minute timed run
tells you on a Vanderbilt start. Only it works in current and you would
not have to do the first minute of your example 2 minutes start sequence.
You could just hang around and know when to head to the line.
I just need to get motivated to take on a new big unknown project.

RE: [Cal_Boats] Regatta basic & start timer

I would think the app would need input from several external devises. Wind
speed and direction (anemometer), through hull speedo to provide your
through the water speeds, digital compass and GPS to provide adjusted COG,
SOG (which could also provide drift or current)
Then your program would require a complete set of polars for your boat, sail
plan etc. I think Demo has a program for developing polars for your boat,
based on empirical data collected during sailing.
Would you also need some way to measure the actual load on your sails. i.e.
if you are headed to the line, on a close reach, trying to slow the boat by
luffing the sails, what input to the program would change your ETA?
It sounds like a very ambitious and complicated program. Based my view of
your website, you definitely have knowledge and resources to make this
happen.
It would be nice to have all this in a "black box" gadget for less than a
boat buck. J
Good luck

There are apps that will tell you your ETA to the point on a line you are
headed to. This will work during the return portion of the Vanderbilt
start. But as you know, by then you are already too early or too late. I
personally don't see the benefit of these programs because they are only
good for adjusting if you are early. If you are late, you are late. They
have other problems as well but even if they were perfect, if you are early
your remedy is to slow down, then you end up being on time but slow.
I write programs as you know if you visit L-36.com. I am also a retired
measurement guy. I made a career out of figuring out how to remove errors
from measurements. I also race sailboats. This combination makes this a
very interesting problem.
So, just to be clear, what I am thinking of is something that will tell you
when to start your approach to the line just as your 1 minute timed run
tells you on a Vanderbilt start. Only it works in current and you would not
have to do the first minute of your example 2 minutes start sequence. You
could just hang around and know when to head to the line.
I just need to get motivated to take on a new big unknown project.

Allen,
I think I understand your problem from the explanation below. A variation
of the vanderbuilt start is what I learned when I started sailing/racing.
Sail away from the line on a tack that will match boat speed on a reciprocal
course back to the starting point. 1 min. out, one minute back.
I do not have a expensive chart plotter or even one of the newer more
accurate GPS. I can set a waypoint at a spot on the earth (starting line)
and set the GPS to show me an ETA to that point. Of course it is only as
accurate as my 10 year old GPS will calculate.
And you are looking to have the GPS or Computer program to calculate the ETA
to a line on the earth rather than a specific point. (maybe a series of
points would work) I am not a computer engineer nor GPS programmer. I
would like to see if this application is available, I think it is workable,
but the science of this application is well beyond my experience.
Good luck,

Subject: Re: [Cal_Boats] Regatta basic & start timer
Michael, I also use a clear start watch. I also try for clear air. I have
done calculations to try and figure out what the relative advantages of
"clear air", "favored end"., and "more wind" are and "favored end", which is
what most people read about and where most of the boats are, is at the
bottom of the list unless the committee isn't at all good at setting the
line. I usually start away from the other boats as a result, typically at
the pin end with the rest of the fleet at the committee boat. I am usually
the first or second boat at the first mark and considering that most of the
fleet owes me time, as much as 68 seconds a mile, that isn't bad.
The Vanderbilt start is based on the principal that a boat will go the same
speed on a run at 135 degrees to the wind as it will on a beat at 45 degrees
to the wind. Therefore, if you know how long it takes you to turn you and
subtract that from the time you begin your start sequence (at the line and
heading away from it) then allow half the remaining time for your return
trip, you will be at the line when the gun goes off.
However, this doesn't work if you sail in current, or if you can't get to
the right place to start the sequence, or if you want to approach the line
on a reach, or...
The app I am proposing is just a way to do a timed approach without having
to time the thing with the run. If you know where you are, and you know how
long it will take you to get back to the line from that distance, you can
time it to be there on time. If you want to allow for some extra time
because of traffic, start your turn early, there can be a countdown on the
app.
Personally I would like an app like this. I see from the replies that most
people do not and that certainly removes motivation for me to write it.
Maybe I don't need it. I typically win the start without it, typically win
the race, and have won our summer series for the last couple of years. I
won the Master Mariners by 10 minutes last year so maybe I shouldn't even
worry about the start. On the MM, I went for clear air, and was a football
field away from all the other boats at the start. That particular starting
line is not set perpendicular to the wind so a Vanderbilt start would be
impossible. We did our timed run by timing by eye where we should be and
timing how long it would take us to get to the line from there. We did it
the day before. How nice it would have been to be able to calibrate that
same day in the actual wind we were racing in. You would not even need to
calibrate at the starting line, just in the same wind at the same approach
angle.
But whatever works for you. Best of luck on the race course.

All,
A starting watch/timer is invaluable. We use a Ronstan ClearStart model.
With buoy racing, the race is often won at the start. Racing in a class of
boats with a wide range of handicap ratings, the general rule of thumb is go
for "clear air" and away from larger/faster competitors "dirty air".
On Magic, we typically use the Vanderbilt Start. Google it. As "weekend
warriors" with rotating crew, it has proven to be a consistent winner for us
to be at the line at 0:00.
Assign a crew member to operate the watch and announce time remaining till
start. Be at or near the start line at the 5-minute signal. The timer,
tactician, and helmsman need close coordination. Grinders, railmeat, and
trimmers should preload leward winches/sheets to be ready at all times.
Lazy sheets should not be underfoot in the cockpit.

Getting a good start isn't all that hard. What works for me is a very
sophisticated devise that is attached to ones wrist. It is called a
TIMEX....with Chrono. Find yourself along the start-line during the 5 or 10
minute warning, sail away with your timer set while on a coarse that will
give you an optimum return to the line. What electronics can not do is
assess the actions of the other boats and often finding the best position at
the start will require some quick un calculated manuvers.
Too many electronics take the attention away from sailing fast in the right
direction.

That was a nice watch, one of my competitors uses it. But what were are
talking about here uses GPS so you could be just sitting in one spot luffing
and the app would tell you when to when to head to the line, assuming that
is the approach you had the app train on. The watch was for strict timed
runs back away and back at constant speed if I understood correctly.
Let me give an example. On the Master Mariners last time we started by
running parallel to the line, which is aligned with the wind, not
perpendicular with it as is typical for a starting line. At about the right
time to the gun, we hardened up and headed to the line. We were early so
had to do little S curves to kill time. With a trained GPS app, it would
know how far you were from the line, how fast the boat would be going at the
line, and how long it takes to accelerate so it could tell you exactly when
to harden up.
I might just have to write it myself.

It actually isn't that hard to get a start line in something. You can do
that with any GPS by asking for track error (I think that is the term) to a
route between the ends of the line. That will tell you the distance to the
line. BC Racer will tell you how long it will take you to get to the line

That said, can Expedition tell you when to turn around and head back to the

I think Expedition is best for long races where it is helping you find the

No, it is simple. All you need is the GPS in the phone. You do a practice
run. Go to the line, turn and go away. Press the button right at where you
want to turn back to the line, turn the boat and build up speed to the line.
Press the button again when you get to the line. This practice run should
be approximately what you plan on doing. In use, you start the app as you

from the line with the same amount of time left as at practice at which

and using that to determine when you need to start your turn. Simple
calculation... for a computer. If you are late starting your run away from

than in your practice run. Distance based on speed at line during practice
and time left.
It is a perfect calculation for a computer and I am surprised nobody has
coded it up. Everyone just codes up how long it will take you to get to the
line at your current speed. What it is telling you is that you are either
early or late. Better to make an app that tells you how to be on time. I
think this would get you much closer to on time than the normal app which

The plastic rub rail was original. I've had the boat since 1987. The cap
was always screwed on horizontally. My 227 also had the same mast section
as the 25-2. Other differences included an engine shaft that came out closer
to the rudder than others making it very difficult to install a folding
prop. The transom is down ~3 inches and the bow is up the same amount.
There were only six boats made after this one so I think they were using
whatever parts they had on hand.

Since I just happened to be cutting up a CAL 25, here is a shot of that deck
hull joint and the area that can trap water. I did not know that any of the

Michael,
On my 227 the rub rail is hard plastic that slides over the two flanges
that are on the hull and deck sections. The plastic piece is attached with
screws that go through the vertical section of the rail and in between the
two flanges. A soft vinyl piece goes into groves in the rub rail to cover
the screws and aluminum caps cover both ends of the rail. And it leaks!
The rub rail design is dumb, the resistance to breakage of the hard plastic
is near zero when it is new and much worse ten years later. The hull and
deck flanges were pop riveted together and glassed on the interior since
this interior section is or was covered by cabinetry or carpet full
inspection has not been possible but I'd bet that some of the glass has
failed or that one or more of the original screws went through it.
Other versions of the CAL 227 had the rubberry rub rail, which I had on a
CAL 25. This rail slipped over the two flanges without any flanges It is a
better seal but becomes very chalky and after a few years many people put
screws in from the bottom in order to keep it attached. A friend installed
one on a CAL 28 by first heating it to make it very pliable and then
stretching it so that when it cooled it would become very tight. This
rubrail was continuous from a stern cap on starboard to one on port.
Good luck on your project, the approach that was taken on Mariposa
http://www.mariposasailing.com/hulldeck.html is probably the only one that
would stop the leak.

The plastic rub rail was original. I've had the boat since 1987. The cap was always screwed on horizontally. My 227 also had the same mast section as the 25-2. Other differences included an engine shaft that came out closer to the rudder than others making it very difficult to install a folding prop. The transom is down ~3 inches and the bow is up the same amount.
There were only six boats made after this one so I think they were using whatever parts they had on hand.

Since I just happened to be cutting up a CAL 25, here is a shot of that deck hull joint and the area that can trap water. I did not know that any of the 27s had a hard plastic rail (probably not original?). There are now a few vinyl rails that do not chalk (as much).
John, I always use t he screws from the underside. Maybe it actually helps drain that area?

Michael,
On my 227 the rub rail is hard plastic that slides over the two flanges that are on the hull and deck sections. The plastic piece is attached with screws that go through the vertical section of the rail and in between the two flanges. A soft vinyl piece goes into groves in the rub rail to cover the screws and aluminum caps cover both ends of the rail. And it leaks!
The rub rail design is dumb, the resistance to breakage of the hard plastic is near zero when it is new and much worse ten years later. The hull and deck flanges were pop riveted together and glassed on the interior since this interior section is or was covered by cabinetry or carpet full inspection has not been possible but I'd bet that some of the glass has failed or that one or more of the original screws went through it.
Other versions of the CAL 227 had the rubberry rub rail, which I had on a CAL 25. This rail slipped over the two flanges without any flanges It is a better seal but becomes very chalky and after a few years many people put screws in from the bottom in order to keep it attached. A friend installed one on a CAL 28 by first heating it to make it very pliable and then stretching it so that when it cooled it would become very tight. This rubrail was continuous from a stern cap on starboard to one on port.
Good luck on your project, the approach that was taken on Mariposa http://www.mariposasailing.com/hulldeck.html is probably the only one that would stop the leak.

Re: [Cal_Boats] Regatta basic & start timer
Allen Edwards2012-02-04 15:48 UTC
I am thinking GPS only. All you would need is your cell phone and a $10
app. It would depend, much as the Vanderbilt start depends, on retracing a
pre-determined approach to the line. You would do a practice calibration
run where you sail the course you intend to sail to the line. The idea
being there are two points in time that matter. The first point is when
you start your approach to the line. The second point is when you cross
the line. In your practice run, you supply both points to the app. In the
real run, the app supplies the first point and hopefully you cross at the
start gun. If the practice run and the real run are identical, you don't
need the app, you will be on time. The largest error will be that you are
not in exactly the same place with the same time remaining. The app would
take out most of the error caused by that by knowing just time and
distance. There are second order errors some of which could be taken out
with the GPS information alone and some with full instrument input. But
full instrument input is beyond the scope of what I am thinking of and I do
not believe is necessary. Anyway, those are my thoughts.

Re: [Cal_Boats] Hull to Deck Joint Leaks

John,
Was your boat made in N.J.? Nemesis has a similar rub rail, and was
#127 0f 135 3-30's. I've often wondered if the "regular" Cal rub rail
would work if the plastic strip was removed. We are more than overdue
for new rubber.
BTW, thanks to all for your discussion of my rudder/tiller slop.
Since I will soon have to replace the tiller (rot and delamination),
I will address that whole situation then.

I believe that the "regular rub rail would fit, the flanges that it attaches
to are still under the plastic one. The end fittings are the only potential
issue but they look close. On my Cal 25 the rubber rubrail was continuous
around the bow and only had fittings at the stern. Personally I like the
looks of the plastic one much better, it just serves no purpose, as soon as
it touches a piling it breaks.

Michael,
On my 227 the rub rail is hard plastic that slides over the two flanges
that are on the hull and deck sections. The plastic piece is attached with
screws that go through the vertical section of the rail and in between the
two flanges. A soft vinyl piece goes into groves in the rub rail to cover
the screws and aluminum caps cover both ends of the rail. And it leaks!
The rub rail design is dumb, the resistance to breakage of the hard plastic
is near zero when it is new and much worse ten years later. The hull and
deck flanges were pop riveted together and glassed on the interior since
this interior section is or was covered by cabinetry or carpet full
inspection has not been possible but I'd bet that some of the glass has
failed or that one or more of the original screws went through it.
Other versions of the CAL 227 had the rubberry rub rail, which I had on a
CAL 25. This rail slipped over the two flanges without any flanges It is a
better seal but becomes very chalky and after a few years many people put
screws in from the bottom in order to keep it attached. A friend installed
one on a CAL 28 by first heating it to make it very pliable and then
stretching it so that when it cooled it would become very tight. This
rubrail was continuous from a stern cap on starboard to one on port.
Good luck on your project, the approach that was taken on Mariposa
http://www.mariposasailing.com/hulldeck.html is probably the only one that
would stop the leak.

Magic has a teak rub rail with SS cap. A PO attached the teak to the hull

I assume the Cal 2-27 joint is an "outward flange" as shown in the attached

Take a look at rubrails.com which shows the detail for the "hard plastic" component and the "soft vinyl" cover for it. I had this system on a Beachcomber 25 which did not have the Cal's interior fiberglass seam and, boy, was it a leaker. Marine Concepts, the builder of the Beachcomber, through-bolted the deck to the hull and covered the seam with the plastic unit, then through bolted the plastic unit. As I said, it was a leaker. There was only a thin bead of caulk between the deck and hull moldings.
I have no rub rail on "Knackered", my Cal 28. I have a clear view of the fiberglass seam on the interior and it is still completely intact. I am considering purchasing a length of red industrial hose and splitting it lengthwise, then installing it over the seam on the exterior. Maybe not that pretty, but, would serve. Remember, she's knackered. My objective is to keep her sailing, not to restore her to perfection.

Replacement rubrail for Cal25
Mark Cosens2012-02-05 00:13 UTC
I have been watching the conversation on hull-to-deck joint hoping to hear someone suggest where to get replacement rubrails. I have heard of a company in California that sells rubrail for the Cal25 but at $500 or so. There must be other products out there that will fit and look OK and not cost more than I paid for the boat! Any ideas?

Check out D&R Marine. I bought my rubrail from there, as did a few other boats from my club. Its NON-Yellowing/Non-Chalking... I sail out of Detroit and the ones that our fleet purchased from SEALS SPARS did yellow and chalk after 2 seasons. Price is about 300 bucks for almost 60 ft as I remember. They gave me way to much. I have had mine for 6 years and it looks new.

Re: [Cal_Boats] Regatta basic & start timer
Gerald Sobel2012-02-05 23:30 UTC
I'm wondering, does my Garmin 76 tell me my ETA to an MOB to within a minute, or to a second? If it is to a minute, it beats getting mixed up with the boats in the next start, or being really grossly late. And doing a Vanderbilt start (Vanderbilt is my middle name...my Mother said I could make up any middle name I wanted, and I don't think Hilton was much of a sailboat racer..am I wrong? I never use the middle name, haven't used it in many decades, so it never fails to amuse me when I receive a letter from some marketer with that middle name.
Another thing, when you get ready to make the reverse turn to the start, don't you really HATE IT when some other racers are zooming toward you on a starboard tack get in you way? Aarghh!
Jerry
PS. Another idea may be to time yourself starting from a starboard to port turn on the start line so you don't have to guesstimate so much how long the start run turn will take. I've never tried it, so I don't know if it's practical.
Re: [Cal_Boats] Regatta basic & start timer
mike farrell2012-02-06 01:15 UTC
Yes Jerry It's practical! I started many races from the Golden Gate YC start line where north end of the line was X buoy and the "boat" end was the flag on shore. With the usual west or southwest wind the inboard end was most favored on a flood tide. I often started on the port tack just off the rocks and port tacked the whole fleet, other times I took a stern or two before coming over to get better relief inshore. I would also start on Stb. at the "boat" end and call for "sea room" before tacking to port. With strong tides I have seen boats as big as a Santa Cruz 70 do a dinghy start with kevlar/graphite flogging 2 boat lengths from the line.
