odd crack in a 25 Seafari

[Blue_Heron]

Connor,
To me, it looks like the hull flexed and put the chine/strake in compression causing it to buckle in the area of the crack. I took a look under the deck of my 25 yesterday afternoon. The stringer runs along the step in the hull and goes well forward of the location of your crack. The stringers are vertical, but because of the deep vee, the force acting on the hull will have a pronounced lateral component that the stringer may not support. The stringer is not in contact with the cabin liner, and there's no bulkhead between the cabin bulkhead and the anchor locker, so it has no lateral support that might help it resist the lateral component of slamming loads where the crack occurred. I'll check again, but I don't think the stringers in my 25 are foam filled. I think they would be considerably stiffer if they are foam filled. I'll try to post pics, but my DSL is down at home and I may not have internet access there for a couple days. strick will probably have his pics up first.
