Wow, that was really a crappy way of "forming" the ribs. It's really no wonder they are all cracked. I'm not a tin guy, but is this normal in these boats? Seems to me it needs gussets for strength.
How did your foam look before you started was it wet I didn't pull mine because it looked good
You don't have to make the bridges go to the outer edge of the ribs, just like 6" up on either side of the V.
I see, drop that fish tank in where it sits and get a shot of it with perspective for distance to the bottom of the V, it looks like it has a flat spot on the bottom. In that splint design there would be no benefit to the bent top cap, just more holes in the rib to start cracking.
You can do that but if you put a splint on the rib foot made from 1/4" AL stock and using the existing holes through the bottom like I did then no new holes and you'd be amazed at how 1/2" total thickness of AL per rib will strengthen that.
Guess you have some ideas and options now at least.
Wow, no wonder it cracked. That's a lot of weight from the top, and force from the bottom, pushing and pulling that weakened area of the rib. Bad design IMO.
