I acquired a 15 with extensive stress cracking thoughout the entire interior. It is nice and dry since it been in my garage to over a year now. I have come to the conclusion that to prevent water absorbtion I need to refinish the entire interior of the hull since the cracks are everywhere. There is even staining around some of the cracked areas. Has anybody had this problem, and what are my alternatives. All I can figure is that the boat must have been exposed to freezing water in the interior. The hull is all stripped of seating and hardware. Thanks for any suggestions.

I think I need to fill in the cracks, and then paint the entire interior. Otherwise I think she will absorb water. She's been sitting in the garage for almost 2 years now, so it is the time to do it if I ever will. I hate the thought of it, but I think its the only solution. The trick is to do it in a way, that the cracks don't just open up again. ???????????? Help !!!!!!

I have done the following with success. I take a cabinet scraper, dremel tool, Pro Prep tool, basically something to run through the crack to create a V shape. The wider the better. I usually use Epoxy with thickening additives like Carbosil or an epoxy fairing compound and simply filled the crack. Just sand flush when the epoxy has cured and prime/paint or gelcoat. I read something interesting on a post a while ago that said that the cracking may be due to the foam delaminating from the hull. They suggested injecting epoxy in strategically drilled holes to solidify the hull to prevent flexing/cracking.

Best of luck!

Only problem is I have about 1 million cracks to deal with. Almost all of the deck is solid and not spongy. There is only one area which has flex. I am thinking of using a thick liquid for the first coat to soak into all the cracks.

Maybe just squeegee on a coat of unthickened epoxy, sand, filler or a high build sanding surfacer, etc... To be honest any way you slice it, you are looking at a lot of elbow grease. This is probably why new boats are sold!! I am sure that you'll figure out something.

Best of luck!
