Yes, it was the same shape as the cal40 apparently, but when the hull got shorter, it steepened the angle between the shaft and the keel, and when we tried the first install, the forward edge hit the hull before it was all the way in.

Helen also gel coated repairs...
Shoemaker (sp) designed..
Cal 40 elliptical rudder..
Also we have a true spade that
Now turns 360° which helps
Backing out of slip...
The cal 36 has no strut..
So prop is far away ..this help s
In 180° also keeps tiller out of
Cockpit went at rest...
This longer deeper rudder help s
Keeping boat flat.(flat is faster on this boat,.).and when Skulling gives
more power ...only problem is flipping rudder
When moving.. you may get squished
11,000 lbs of force.. we love our Foss..
It is probably the best up grad for
$ 1600to 2000...on our 50 year old
Boat. We used foss in Costa Mesa
So we could save shipping cost..

Helen, now I understand what happened. You had to taper the new rudder's dorsal to ventral aspect in the cephalic direction, as opposed to it's medial aspect, or, put in laymen's terms, top to bottom going forward as opposed to side to side thickness, or, tapering the stainless steel shaft, for that matter. Wow, was I confused! But the shape of that new Foss rudder must be sexy as all get-out, enough to make a lonely male Orca amorous!I was looking at a new (oh it's new compared to me boat) 1978 Cal 34-III. Nice woodwork inside, real cherry wood comparable to the most expensive yachts, like a Swan or Hinkley's, altho I've never been. The V berth looked small compared to my Cal 24-1 but when I tested it out with my 6'4" bod stretched out, there was length to spare. Bill Lapworth was 6'5" and one feature his boats always have that it seems I don't find in other boats is generous length berths. The only thing that was lacking was standing headroom, but I could stand OK if I slouched a bit.It's a tempting buy, altho for my needs perhaps I should stick with my Cal 24-1, it being that small boats are always more exciting to sail on than bigger ones. But the big Cal does have the capability of crossing oceans in comfort, I assume, or hanging out at an anchorage. But is that something I really need to do relative to the majority of my usage style, which is buoy to buoy and coastal racing?The boat doesn't have anything to assisst in raising an anchor. Is a manual system adequate, or should I consider installing a windlass or a capstan, not that I like adding weight to bow or obstruction on deck. I did find this baloon gizmo that slides down the anchor rode and floats to anchor up to the surface. Cool but not useful in a tight anchorage!Gerald of ye olde Shpritz, the original Cal, Cal 24 Mk I.

Jerry, I looked today by chance at cal 34s in the Oregon Washington area on CL. The price ranges are amazing. Before we bought Caliente we looked at 34s from San Diego to Long Beach. All but one were full of termites due to warmer climes and that doug fir plywood the galley cabs and whatever else they used it for. If you open the cabs, look for the little pill dust that gives it away. Note #2; the cal 34s that are a newer model have the galley sink and ice box by the cockpit bulkhead, and reduce the need to worry about the (gasp) dreaded beam caused by the draining ice box hose (in the starboard forward galley version) onto that beam/mast pillar that goes up and supports the deck stepped mast. Just for fun, check out the Seattle 34s. Helen.

Helen, thanks for the heads up. I see the nice Cal34-III in the Seattle area for $29,500. It has spinnaker gear the one here in MdR doesn't. The one here has no poles of any kind, either, but it's $7500 less. The paint on it is 4 years old. And no capstan or windlass. The Westerbeke is well maintained looking, by the color of the paint, nice and red. Actually, the current owner seemed knowledgeable. He's selling it to buy a bigger boat, 'cause his other half wants bigger. To me the Cal 34 seems plenty big, especially compared to my Cal 24. It even has a shower!
There's also a Cal2-34 in San Diego with radar, well prepared, recently back from a 1000 mile Mexican cruise. The owner seems to charter vessels in San Diego. I've gotten the impression that charter companies only want to rent boats that are fairly new. I've thought of getting my captain's license. I've had the Coast Guard Aux. courses in Basic Boating/Sailing, and Navigation. The later I showed up for the first class, and the last class to pick up the take home test, and the final exam, relying on my foggy memory of navigating air craft to ace the test. However, I've heard the captains test is a lot more challenging than that. True? And...do they have a section on performing weddings...and...funerals?

The CG 6 pack license (you could go for masters or tonnage at very little more money andclass hours. Example, Sequoia YC had a qualified guy teach a class last year and I took one in 2007. It gives you what the CG wants you to know (i did 6 pack), and then you take the exams, on for ex; rules, navigation, safety.... When you complete the tests (which you get at least a 2nd chance at) and you pass them all, you take it to the next level(CG accepts the tests as satisfactory to them) and take all your experience, hours, days, years to satisfy the type of license you qualify for. 4 hours a day counts as one day pn the water. you can go back and have any skipper you sailed with or boated with verify your hours on their boat. Your own log book, your Navy experience, etc. And you must be free of crimes in your past, and they will probably not allow much alcohol history. A few guys got up and walked from my class when the instructor went over the details that could matter. I didn't pass the rules, but I did all the others. I missed a couple based on right of way, imagine that. I also was healing from some back surgery and the drive from Santa Cruz to Pt. Richmond to retake was more than I was up to and my ego was bruised. Starboard is not always the default answer. Aside from that, I recommend you take it if you can. Then, remember that if you are the licensed captain a tremendous liability is upon you. I had wanted to be able to use our trawler to do little couples cruises to Jack London Square, Sausalito, etc.overnight or just day trips. We are now about to sell our trawler to the city of Redwood City /Docktown closure and the last day of ownership if we do is feb. 28. Unless lawsuits prevail. by June the Marina will be gone and over 140 condos will be built 39 feet from the banks of Redwood Creek. The twisted way this came about, is unbelievable. Helen
