Starboard is good stuff for some uses, but look into it carefully. Starboard is not intended for structural applications. It is also at least 3x the cost of marine ply and double the weight. Epoxy coated marine ply is much stronger, lighter and would last a very long time.
If it's just a small area and the structural aspect isn't at issue, a penetrating epoxy sealer might be an option. You would need to dry it out first tho. I've used this product
to successfully repair rotted fiberglass boat deck coring.
