use of traveller

Listees: I'll inquire on this list, which has more racers than the list for my other boat. My Cal 20 does not have a traveler (but should). The other boat does. The question is about proper use of the traveler. The other boat has an old one (early '60s) that I'm thinking about replacing this winter because it's very hard to use--lots of friction. I've assumed that you use the traveler primarily to control the amount of mainsail twist. If you sheet the main in and then use the traveler to control the boom position, you can keep an untwisted main that draws evenly (more or less) from top to bottom. When you need to let the main out some, for a puff or for general trim, you just let the traveler down to leeward. If you want a main with some twist so it luffs toward the head and depowers the sail, you can move the traveler amidships or to windward and let the sheet out more so the mainsheet is at an angle from the vertical, pulling down less. Have I got this right? If I'm right, you'd use the traveler to leeward mostly in moderate winds, when you want the perfect foil-shaped mainsail, and you'd pull it back to center or even to windward when you wanted a fuller sail shape in light air or when you really wanted the head to fall off and luff as a means of depowering in high winds. Advice? Chris Campbell

Essentially Correct, Windward for Twist, and making a slot for larger genoas. Recall also that the wind itself, "twists" as it get farther from the surface, the friction with water "bends the air" @ 15% or so,,, that's why waves are a bit harder to sail through in starboard.. generally, so you put more twist on your starboard trim to power up the boat. See Coriolis effect (Wind Shear). Wind Sheer When there is wind-speed, there is wind shear! What is wind shear? The main reason for wind shear is due to the Coriolis force. The wind will rotate counter clockwise on the North Hemisphere around the centre of the low pressure. Then, there is a friction between the sea surface and the free air above. This friction will slow down the airspeed at sea level and gradually up into the free air above. This friction will also decrease the effect of the Coriolis force, so the wind will shear (to the right) from sea level up to the mast top (and above). The wind transducer will only measure at one altitude, so you need to understand and consider this sheared angle to adjust the sail accordingly down to deck level. Note! Several meteorological effects will have impact on the size of the sheared wind. When cold and warm air is mixed with faster winds from higher levels, gradients and sheared winds may locally change very fast. Generally, by applying sail trim according to the size of wind shear, you can get more power out of the wind on starboard by adding more twist to match the shear (on starboard only). This will reduce the top force from the wind, move the pressure centre downwards and allow for a more forward pointing and efficient wind force. The wind instrument will "show you" that you are sailing lower than port side, but it is only a relative illusion since the reference is from your average attack angle and sail trim including wind shear. On port side, the sheared wind is "negative", and it requires more flat sail trim. The instruments will tell you that you are sailing high and fast on port tack, but this is also a relative illusion, but opposite from starboard tack. You have less wind force in the top of the sail, so the efficient wind pressure centre is moved downwards. Then, for a given heel angle, you will have a wider wind angle, which mean that you are actually not sailing as high as the instrument says! At open sea, where wind direction is stabilized, the waves will follow the wind direction that occurs at the surface. Since this wind-speed is reduced by the friction, it will therefore point towards the low pressure. This means that you will hit the waves slightly harder on starboard then port side (on the North hemisphere). This is also a reason for adding more twist and power on starboard tack!

Rog recently sent me an email about the Cal 28 liking a bit of twist in her sails. While I'd stumbled across references to "twist" before in sailing materials, I wasn't really sure how to accomplish the manuever. After spending some time online and Google, I realized, finally, what the traveler was really used for. I spent this weekend determined to get a twist in both the main and genoa. In the light air of San Diego's bay and Point Loma, I opted to keep the traveler to windward side. See position in attached photo of Debbie at the helm. Note, too, the work of the power thruster, as we motored towards the blue water, where we cut the engine to chase the schooner shown. Thanks for these finer points on proper use of the traveler. Just the sort of thing I was hoping to pickup as a member of this fine group. Thanks for asking about it, Chris. I talked to the marina and the Cal 20 is still available. I told them I might buy it just to practice my painting, fiberlglass, and carpentry skills.

Timm... I'm a little unclear on this one. Between 20' above the water and 35' above the water, how many degrees of wind direction difference would you expect to find ???

Fin - We use the Nexus T.R.U.E. feature to tune the boat before every race. The Wind Shear changes with conditions, wave height, wind weight, air temperature, leeway etc. The T.R.U.E. feature can even be used during the race to recalibrate a changing condition. To use the feature, you'll need the new FDX Server, FDX Software (free), 1 meter Twin Fin wind transducer, and the "non-amplifier" depth transducer. A starting point is @ 7.5 degrees.. sometimes more, sometimes less....

Actually Chris, the Windex is an invaluable tool for shorter races, as it is generally more responsive/ sensitive than a transducer. The transducer benefit, is to help keep our eyes "in the war zone" verses looking up at the sky. I use the Windex, and tell tales on the shrouds, primarily when we are doing buoy popper races on the Columbia.. Popper races is my term for very short legs, popping sails up and down every mile or so. My favorite (low tech) wind reading tools: Backside of head, after a new haircut, Shroud Tell tails - a furry string fiber Windex Water Ripples Cigar Smoke Land Smoke/ Flags Puffy Clouds with flat bottoms. Clouds along a shoreline The very Nice Nexus Instruments/ software is useful, once you get the boat established on a beat/ run, to maximize Sailing angles, Target Boat Speeds, and waypoint closure. Also the better transducers provide good information for us to use in our weather routing software and tactics. dEmO From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] On Behalf Of Chris Campbell Sent: Wednesday, October 04, 2006 12:35 PM To: Ca… [at] yahoogroups.com Subject: Re: [Cal_Boats] use of traveller - Fin ti… [at] ch2m.com <mailto:ti… [at] ch2m.com> wrote: Fin - We use the Nexus T.R.U.E. feature to tune the boat before every race.

Fiver, I'm proud to say that there are a large number of Cals on the River. I have a Cal 20 (Culo Bagnato) and Cal 9.2 (Freewind) on the river. Our Cal 20 Fleet is possibly the strongest in the USA, with 43... 12-20 are lined up on race days. There are many that are cruisers, from 25-36' and at least two Cal 46's. We moved our Cal 40 "Victoria!" to Richmond California in 2002. She is now my parents boat, and named "California Girl" My favorite Cal on the River is a Cal 43... WOW, is she a beautiful and well thought out craft. Pictures are at: http://www.sailingtexas.com/scal43a.html when she was for sale last year.

Mike Jr and I flew up there in 2004 to buy that Cal 43. The guy had convinced himself that the chain plates needed replacing. He might well have been right but he placed them on the outside of the hull, like a Westsail 32. It ruined the boat. It has been around the world but had lots of cruising gear that was old and we didn't need. It had a couple of potential problems but is beautiful, as you pointed out. His price was too high (It has come way down since) and we would have had to have repaired the holes in the topsides and probably have had to paint the hull. We decided to look for a Cal 40. For cruising, it is great. It has two heads and an aft cabin with a double and a single berth. The other great advantage for California is that it will fit in a 40 foot slip. I looked at a Cal 48 about 8 years ago that was also beautiful but I would have had to leave it in Mexico for years to get a 50 foot slip. Had he lowered his price to what it is now (He may have sold it since) I would have bought it and saved about $50,000 restoring the Cal 40. No Transpac, though. The 43 weighed 22,000 pounds before all the gear.

I had a haircut on somebody's back steps just before working in a southern state back at the end of 1969 and another one given by my dad in the kitchen before interviewing for my current job in 1994. I guess the next one's due in 2019. So a few years back I went out and bought a whole ball of acrylic knitting yarn in a bright red-orange color. It makes great tell-tales, both on sails and on rigging. It'll probably be in use long after I've expired, at the current rate of consumption. And it saves me the indignity of a haircut.
