I used Starboard also, having gone through two marine plywood versions. Original cockpit hatch covers were lost in a hurricane. The Starboard stuff works okay, will last a lifetime, but what I got wasn’t thick enough to hold the hinge screws without them showing a bit more than I’d wish. Also a bit slippery when wet. A non skid covering would be good but so far, 5 years later, such improvements are still on the to do list. I’d rather sail the damned creature than fool around with sticky stuff or gritty paint. Same goes for my window gaskets. They don’t leak, yet, in a 1972-3 boat, except a bit of black sort of powder from oxidation I expect, the dark smear comes off of the gaskets in spray or rain, streaking the gel coat, but is easily washed off. The gasket material recommended in this string is something interesting I might be pursuing... but having rebuilt almost everything else, I’m in no rush to finish. I just love, as Ratty said, messing about in boats, but to be honest, I love mostly messing about in my boat, Penelope. from my pad nn
