On my boat, the entry was made up of multiple pieces of teak, fitted together, tongue and groove, with with ply fillers and large glass windows set into RTV, and held together with a few screws. Few being the really important word there. Due to the design which inclines from bottom to top 10 inches on a 60 inch rise, water rains directly onto it and drainage from the flybridge also washes over it. Over the years the door warped, and started to work the framing . As well the wet and dry cycles also opened everything up. No amount of caulk would help. After 2 years of being covered the wood shrank and gaps in the joints really opened up. I decided to rebuild this while I'm doing everything else.
My intention is to replace the framing, center the door and install 2 smaller sliders instead of the fixed large glass panes.I would like the weather surface to be a single sheet surface, to eliminate water ingress. I think a sheet of marine ply would be quite heavy. The area covered is 64 x 96. Plainly weather resistance is a key requirement, as is cost. It certainly needs to be under a 1K, preferably half that. Also I can't find any suppliers of doors, in the size range, 24x60. I thought of fiberglass storm doors, but none are that small or are reducible due to form. Although I could make a new wood door, that runs counter to my goal of eliminating exposed wood.
Entry bulkhead as original built.

Ideas would be appreciated!
