Regrettably, this H17 is now past-tense. While chopping it up, I did confirm a few things that contribute to the observations on the H17's construction and design.
1) The bottom half of he hulls are very thin. So thin that I when I tried to repair them, I punched through barely after getting through the gelcoat.
2) Placement of the t-bars bolts inside the crossbeams was a nightmare to deal with. I snapped two allen wrench extensions trying to unbolt this t-bars. A third turned out to be mounted at the wrong angle, which I figure out only after stripping the head.
3) Hardware removal - What is the deal with ramming locking bolts right up against the side of the hull so that you can't get a socket around them? What an annoyance.
4) Flotation - I'm surprised to see how little styrofoam is installed. I would have thought there would be cubes installed the entire length, but only found some in the very back. Maybe this is another result of a PO's work.
To address my earlier questions as to why this H17 was not coming apart, a PO had indeed glued the hulls to the crossbeams which contributed to the problem. The PO also installed backing plates under the cross-beams and secured them nylon locking nuts. When I tried to unbolt it, the nuts would simply spin. (genius!) In the end this would not have mattered except for the fact there was a one-piece tramp installed. Just how he/she managed to install these plates and nuts implies that the hulls were cracked open.
So who needs parts? I'm looking to sell whatever I can to help pay or the next project boat.
