I've pulled the hulls of my new to me cat, it is foam core fiberglass and the hulls hold their own shape. One hull has 5 ply bulkheads the other hull has 5 foam bulheads. The foam is not needed for flotation and I have chased up a previous owner who put the foam in, he did it because occaisionaly when he pitchpoled the hull would split on the centerline. I dont want to take the decks of again could somebody in the know give me the pros and cons for the different materials. The boat is 18'X 8' with 30'mast. If the recomendation is for foam can you wrap or paint it to stop it from absorbing moisture.
