Building New Companionway Hatch - Columbia 29
The companionway hatch on my newly purchased 1963 Columbia 29 has seen better days, much better days. I am trying to plan a new one, but I have some question about the layup/construction I am hoping someone with more experience can address.
I have several somewhat rotten pieces of mahogany that I plan to use as guides for the radius of the hatch. My plan is the bend two thin sheets of marine ply over these frames and glue them together with a piece of chopped strand mat in order to induce the proper curve. Then glass the entire thing with ??? material and gelcoat. After that is dry I plan drill, pot, and tap some holes down the length of the hatch and attach the sides (that come down to keep the hatch on the tracks) which I will make out of some rabetted mahogany.
Anybody have any advice, or see any major flaws with this plan?
