centerboard stuck

[rboswrth]

I bought an '88 capri a fews years back and sail on the Chesapeake. the center board jams in the slot and requires some major force to move up or down.

I found the problem is both sides of the center board slot have dish-panned inward. I think I also found the cause. The trailer was setup with the roll beneath the slot carrying the weight of the boat and pushing the bottom up. I fixed this but the dish pan remains.

I have put an inner tube into the slot and inflated it. It pushes the the bulges out but they return when the tube is removed.

I comtemplating the next step would be to apply heat with the tire tube but this risks delaminating the fibreglass.

Any suggestions?

Is is possible you also have the wider 1 1/4" new-style centerboard in the older slot built for the 3/4" foil? See this thread: http://sailingforums.com/threads/centerboard-hard-to-lower-raise.26154/#post-122526

Ed. thanks for getting back so quickly, I've seen the thread you cite, but I'm afraid I know what the problem is I just need to know how to fix it.

Maybe someone has some fibreglass experience with heat?

I had same problem. Sanded both sides of board until fit was just snug. When storing for winter I drive wooden shims down each side of board to hold each side of slot open further for several months. Seems to help some.
