Not trying to be a jerk man but your first post made it sound like you’re out of options and transferring everything to a hull that you hate because you can’t fix it. If you have the ability and skill to do what you just proposed, then why are upset that you have to change hulls?
I cut a huge hole in my hull, hood, and tray. I fiberglassed it, smoothed it, made a new seal, primed and painted it, added new footholds, returfed, and had it back on the water in less than a week. It was all free formed too since I didn’t have another hull to pull a shape from. In short, if you have the skill and motivation, you can do it in a week.
PS - We understand this is a carnage forum and it sucks that this happened to your ski. We are just trying to help you out and give you options.
