Delamination Problem
Gil,Sounds like delamination. This sort of problem can be a pain to fix. This was caused by water penetrating the gel coat and getting into the laminate fibre. There are several ways to deal with this, either by drilling holes, leting the laminate dry (along time with dehumidifier) and then filling with epoxy. You can either tackle this from the top surface or from beneath. each has it's own set of advantages/disadvantages. There are several books out on the market that discuss these repairs in great detail such as Don Casey's "This Old Boat" or Nigel Calder's "Fibreglass boat repair" (I think that's the name: not sure).I've also attached a link of someone who's done this exact repair.Good luck, Let us know how it turns out (if you buy the boat)/ChuckS/V Windsongs 85 H23
