That sounds like quite a large area is involved....but expoxy will fix all. While the polyester resin will make a brittle fragile deck repair if you try to pour it, an and epoxy such as the WEST System you mention will make an easy strong repair of such areas if you can get the areas dry. If you can get the boat indoors and have time to dry it out there may be options to open up a few access pour points and allow the epoxy to soak in. I did such a repair on my Grady White cabin bulkhead and found it to be as solid as a rock. One problem, the epoxy cures very slowly and has a somewhat lower viscosity than the polyester resins wer're accustomed to working with. When poured to saturate a rotted core, it tends to find a way out. Make sure you have those sealed up or make a big mess of the rest of the boat, like I did. Remember that epoxy is expensive, but will adhere to polyester and not the other way around.
