i mean... the hull is definitely worth that, its just whether or not you have the time and patience to put up with a project like this. your information says you're in the carribean? Parts for a full rebuild like this could be hard to find there.
in perfect condition, this boat would fetch probably 50-55 depending on the area. you could re-skin it for about 5k, new engine 5k, gel and fiberglass work is probably another 5k (yes, that gel crack at the rudder is probably all the way through the backing plate), all new underwater gear, 2k, and throw in various repairs for another 5k. Do you have 22k in the bank to blow on something like this?
if you do, great, would probably come out ahead, but man, that's alotta work.
