Super Jet worth it or not?

I bought this '90 SN a few months back. I planned on shortening the rear and giving it a nose rocker. After stripping and grinding up the hull I found a few spots that are severely delaminated. I expected it to be a little rough but it's a little worse than i thought. Oh well, it is over 20 years old and I didn't pay a whole lot for it. Is it worth trying to fix it or junk it. I already cut out the area under, where the gas tank would be, which is a pretty big area . Can I repair that to be as strong as before? The cracked area under the rear rail will mostly be gone. But will it be very difficult to rebuild the area by the intake and will it be strong again? I already have a new aluminum pump shoe, so if i destroy it that's fine. Thanks for any input, Jason.

I've done a little bit of glass work but no filling a void of this size. Would I just lay up a piece of glass, cut it to the size of the hole and graft it in, feathering the size of the ajoining pieces larger as I layer it? Does this make sense? Would that yield enough strength for a hole this size? I would appreciate any help from the pros. Thanks, Jason.

it depends what you want bro, its worth using as an experiment if you have the time.
I want to do the same but just cannot find the time.

Unless you "like" fabrication..... you wont finish
put foam in shape it glass it pull out foam

If you are really interested in doing this project, then I don't see anything on that hull that would prevent you using it. My SN had a 3 foot crack all the way through (down the side and up to the bondline), and I patched it up 5 years ago. No problems. What I'm saying is this: if you do it right with the right materials, those defects you are worried about now can easily be made to be stronger than the hull was originally.

Epoxy resins only (no polyester). Also remember that the lower hull is SMC, so it has mold release blended into it. Sanding will release this, and so you want to clean that off the surface before putting down the first layer.

Use proper foam as a mold as already suggested. For the big square hole, taper that out now as much as possible so that the edge of the hole is knife edged. This will give you a larger, roughed up, clean surface to bond the new fabric to without increasing overall hull thickness. Build up a bit at a time with fabric pieces that keep getting incrementally bigger, using more of the taper as you go.
