Are you planning on folding the table against a bulkhead? If this is the case, a standard, stainless piano hinge works just fine. You can anchor the table in place against the bulkhead with a pair of old-fashioned door latches. You can find them at Home Depot, Loews, etc.., they're inexpensive, very strong, reliable and made of brass. I have to go to my boat on Saturday and I'll try to remember to shoot some photos of how my table is held firmly in place.
