Dear fellow Contest owners,

thanks for welcoming us to this forum. We have a Contest 32 from 1978 (model no. 14). It is a ketch. To give you some context, we bought our boat about 2 years ago and are now livaboards for 1.5 years. We are sailing in Greece.

Actually, we have a lot of questions, but the most urgent one is if any of you had problems with the king post sitting directly on the fiberglass hull (pic 1) and thereby transfering too much load onto the hull, which can be seen by cracks on the outside (pic 2). And what did you do against it?
We are thinking about putting a metal plate below the compression post to dissipate the load. (But now even more questions arise: material? thickness? area?)

Or did Conyplex change the design and later on put something below the compression post? Also the problem seemed to have been worsened as our keel is attached by putting two parts around the hull. And exactly were these halves join the king post presses down onto the halves. As it looks some of the previous owners already realized the problem, but only but filler into the crack and did not get to the root of the problem.

I would be really thankful for any kind of input.

Thanks a lot.

Are you sure that the cracks on the outside were caused by the compression forces of the king post? Spreading the load by the use of a plate or another construction might lead to other problems and not solve the cracks.  You can ask Mr. Dick Zaal through his website, he is the designer of this model.

Yes, we are sure that the crack is caused by the compression post. It is a good idea to ask Dick Zaal.
Thanks for the suggestion
