A quick PSA to report on the failure of a rudder blade on the CS20.3. I was sailing Chessie (CS 20 Mk. 3 Sail # 4) this weekend in Raritan Bay, out of the Keyport Municipal Boat Ramp. Tacking gently in about 5 kts wind, there was a soft snapping sound, steering wasn't so good, and we saw a little bit of the boat floating out backwards behind us.
We used the motor, picked up the part, and got back home no problem. Took some pictures to illustrate the breaking point.
Hello - I'm putting together the centerboard trunk and had a question about the pivot(s) for the line that raises the centerboard.
In the drawings, there is one pivot labeled Harken 243 block. Then just below it , there is another thing that looks like a pivot, but it isn't labeled and seems to not totally make sense (I don't see how it would provide any benefit, and looks like it is in the way.) I was wondering if this is a real thing or maybe just an artifact in the drawing?
Building the CS20.3, I'm at the step where we install the hanging knees into the hull after filleting and glassing the keel. I made a really stupid mistake wanted a bigger challenge and snapped the aft hanging knee into thirds, where the cut-outs are for the deck support beams.
I've started fixing this by putting everything in place, liberally applying epoxy, and putting about 8" of fiberglass tape on both sides of both breaks. It seems to be pretty strong now, so I am planning to just clean it up and proceed. But, I am wondering if anyone else had to fix something like this, and if so, if more drastic measures would be necessary?
One possibility I was considering was to add a fillet for 5-6" on either side of the breaks, in the L-shaped corner formed by the overhang of the doubler, and then wrap a second piece of fiberglass around that fillet, which I think would have the effect of approximately doubling the thickness of the "beam" at that point (under the notch for the deck beam). Not sure if this is overkill, but given my ability to break stuff, overkill might not be the worst thing in the world.
