Where can one purchase such holes?

Your local boatyard can creat them. [for big bucks, probably] You want
a door, hinged at the top that will open if pushed from the inside,
but not the outside. How big it needs to be is a question. I say make
them as big as will fit. The door goes on the outside and is bigger
than the hole. That way waves can't stress the hinge.
