Well I was told it was a wamiltons hull with visual cf reinforcement. I don't think the person I bought it from "built" it so I don't want to reveal the seller. Hull has some history for sure. Someone mentioned earlier that the weirdest part is this person obviously had the knowledge and tools to do it right but made crazy decisions at every turn. There were exactly 4 different types of foam, 5 if you count what was in the engine bay. Blue home depot poly, "great stuff" white spray foam (waterlogged), blue spray foam (waterlogged) and a little of what I would guess is regular 2 part closed cell because it wasn't waterlogged. I filled an entire contractor bag to the very top with the tray scraps alone. The bag was 45lbs. I weighed it. (NOT INCLUDING THE TRAY AND FOOTHOLDS I CUT OUT!!!!)I want to know who originally built it.
Since so much needs to be ripped out you could consider a wide tray when you rebuild it. The exhaust tube is crushed so one of the only reasons not to do a wide tray is out of your way since you need to buy a new one, you can lower it when you reinstall it.
It sucks you got stuck with a mess but you can refurb it.
Do you have any pics or anything that kind of shows what you're planning? Hard to picture it. toe hold - like a front foot hold against "dashboard" that I see people have?That is a cool ski, I have read through that thread multiple times. Different people are ok with different levels of "lock in", some like straps, some footholds, some are ok with a wide tray and a front toe hold and nothing else. On my ski I am making a wide tray with beefy solid glass gunwales and a massive toe hold, not because I plan on having rear holds but I am making sure I am ready if and when my riding evolves to the point where I may need or want them.
Your plan is sound, measure twice, cut once, and try not to overthink it either.
Don't believe anyone at this point would want to admit it after we have bashed them so much.
