I'm looking at what I want to change to my Dart 18 for the next everglades challenge, and one thing that became clear is that the gear strapped to the tramp has got to go in the hulls. If I do that, the deck load won't be so grabby of lines, I'll be able to move my weight to sail the boat more efficiently, and overall weight will be lower.
I've talked to some guys who use long skinny dry bags and feed them through round access hatches. This is probably the simplest and most reliable way. The curve of the deck is more than a round hatch can be screwed to, but I can build up a flat spot to attach the hatch.
Is there a way to build or buy waterproof hatches that would be bigger and easier to load? I picture a laminated plywood hatch cover that matches the curve of the deck, but I fear it will leak a lot.
