Default Re: odd crack in a 25 Seafari

Connor,

I think Dave's right, it's a compressive failure. Those small fore & aft gel coat cracks up in the step radius may be the result of tensile/bending stress from flexing in the flat panel aft of the vertical crack. Maybe stringer wasn't well bonded to hull in that area; I've heard of some 23 Sceptre's having problems with loose stringers, so maybe this is a similar problem.

I cc'd you on an e-mail I sent to FiberglassOne and some aerospace engineer friends with a link to this thread, so check your e-mail. Dan has seen that type of failure many times, and said you will probably see a LOT of delamination on inside. I'm guessing you'll have to cut out the inside of the storage box under the bunk to get a look at it. If your glass guy is swamped, either he or Don Herman would be good guys to fix it if you felt like towing it over this way. Maybe we could get together while you're here . . . make a weekend out of it! Denny
