I'm wondering if anyone has any clever ideas for replacing the 'hatch covers' that cover the access holes in an enclosed 'cabin'? In the later year boats, there was a foredeck storage area and there were optional teak covers to cover the holes. I don't know if my boat ever had the teak covers, but someone made plywood variants before I bought the boat and they're not in great shape anymore. Just wondering if anyone had any luck with a composite material, ready made replacements, or a sealed hatch that might work. Thanks!
