Re: odd crack in a 25 Seafari
The really strange part is stringer placement. I can see the other side of the boat and it is the usual massive seacraft construction. The stringer goes well past where the crack is and there doesn't seem to be anything around that would create a hard spot or anything else that could provide the opportunity for such a crack. I guess I'll just have to wait until I can get the bottom out of the storage compartent and see exactly what the crack looks like from the inside.
For sure, there was no sign of any crack when I bought the boat 9 months ago. Entourage, were your cracks right on the stringer?

Re: odd crack in a 25 Seafari
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. Dave

Re: odd crack in a 25 Seafari
The stringers in my 25 are hollow. If the crack is inside the stringer then you are going to want to remove that portion of the stringer fix the glass underneath it and then re attach the stringer. Then make the necessary repairs on the out side of the boat.
