It IS the steel version of the Flyin' Hawaiian. Except HotRod at least made some drawings (presumably), and it did float somewhat on its lines. This boat, I doubt that's the case.1. Cool thread.
2. I really wanted to like that hull, he's trying something different.
3. It's possible that I'm completely missing his design approach here, and I hope I'm wrong, but it seems to be a disaster in the making based on what I saw in video. He seems to assume that the come-alongs will prevent the hull from spreading and the thwarts will prevent the hull from collapsing. But those thwarts seem pretty anemic, and they don't offer any support against the hydraulic pressure below them.
A good steel hull should look like the outside of a steel swimming pool, the pressures are similar, the cross members distribute the forces as monocoque. That poor hull looks like each steel panel is going to have to fend for itself, with most of the the compressive force going to the welds. It seems the steel version of the Flyin' Hawaiian.
