A word of warning...if you plan to use your boat down in this area ( turks and caicos
islands) and in the region generally, and you are doing your own woodworking, be mindful that we have Formosa
termites here. They will eat anything with cellulose in it. They WILL eat cypress, mahogany, teak, and pressure treated wood. Don't believe anyone who tells you otherwise.
Be sure any wood you install on a boat is sealed up enough to keep the little buggers from finding it. They will eat plywood and leave the glue. They will eat the homeowners type of foam insulation
. I am aware of at least three nice boats here that have been totally destroyed by termites within the past year. And the six year old roof of our house.
And a lot of other things. Cardboard. Stacks of paper. Anything with cellulose.
Seal it up well, and you shouldn't have a big problem. Even paint
will do it. But leave no fresh cut edges anywhere.
