That's what I said. Jaw dropping terrible. Scantlings based on a 4chan thread about building a septic tank for recycling urine. And it's not a 15' boat sculpture you shake your head at. You need to step back and contemplate the bad-all-over of this massive thing. And if he does manage to weld enough angle on so it doesn't sink immediately, he will have issues just getting permission to enter a harbor. The guys at the fuel dock might say, "Yeah, nope. Get your parade float out of here."The problem is he's working from no plans whatsoever. There's no weight calculations, no stability calculations, no structural calculations. The frames are cut from the same thin steel as the hull plating. Only 1" in depth. As soon as the boat heels, the keel (woefully under-engineered itself) is going to twist the bottom of the hull, if it even manages to stay on. Haven't yet seen the chain plates or structure supporting rig yet, but a safe assumption they'll also be woefully under-engineered. The hull isn't a developed surface that the steel plating will easily bend around. Thus the big hammer and all the lumps and dents. Pretty likely the boat is grossly as symmetrical, too. He doesn't know how to build a non-developed surface in steel. In short, he's not building a functional boat, he's building a big ugly piece of lawn art. If he somehow manages to launch it, hope he's carrying no innocent passengers....it's a death trap.
I didn't see a cockpit of any sort, just some below the knee life lines. I'm betting this boat sculpture will have total inside-the-pilot-house steering and sail handling, no kidding. He's building a Starship as much as he's building a boat. You could make other bets on the rest of it. Free standing mast? An A-frame mast? Crow's nest? How about shaft angle? An outdrive and engine scavenged from an old runabout he found on the side of the road? It'll be interesting long before the oil canning sea trials.
