Many of you may have followed my earlier post where I talked about using formica inside the CB trunk to slicken it up. Others wrote back to say that was a bad idea, etc. I agree, because if anything goes wrong there would be no way to fix it without practically tearing apart the whole boat.
A few posts mentioned adding carbon to the trunk resin, which sounds like a pretty good idea, but again this is messing with the basic structure of the boat. One thing to make sure of at least is that the areas where the blocking will be glued should be masked off so you don't get any carbon there. And then you run into chemical bonding problems because of waiting too long, and so on. So I have decided against this also.
So now my great brainstorm is to add carbon to the final coat of epoxy on the centerboard. This would make it very slick and with the inside of the trunk's epoxy sanded and polished smooth I should get pretty darn good slippage. And, if anything goes wrong, the centerboard can be removed for repair.
I have a nearly full can of carbon left over from some kayak rubbing strips I made and on the can it mentions centerboards as a potential use. So that pretty much settles it for me. Come to think of it I may have some Dynel left over too. I might apply that along with some more epoxy and carbon to the leading edge--if, that is, I can keep it from making the CB too thick to slide into the trunk. This, along with the thickened epoxy strip CLC recommends, should make for a very rugged centerboard. Unless it doesn't.
