Yikes. You have a lot of work to do. I am repairing a ply epoxy cat in Scotland. Thought mine a bit bad, but now think it is in fine condition! At least being in a colder climate, any potential rot is not so serious. Get yourself a moisture meter, you don’t want to be sealing in damp wood. Epoxy is great stuff, but so expensive. You can use polyester above waterline. Though you need to be very careful with preparation. The surface needs to be rough, then prime with styrene thinned resin, the onto the filler / glass.

Thanks for your thoughts. Epoxy here in the Philippines is relatively cheap, it's not breaking the budget so I'm using it exclusively. Moisture is definitely an issue and why I'm going all out before the rains come. Luckily the timing here has been good with around 4 months of dry weather. But the boat has been rained on and swamped inside with every high tide for at least 4 years, so the damage has been huge. Just doing the best I can. Good luck with your cat.
