The area between bulkheads 1 and 2 is a dry locker, accessible through two removable hatches located in bulkhead 2 right above the front seat. This dry locker also doubles as an air chamber for flotation, so the hatches need to be as watertight as possible. My goal was to make the hatch covers as large as possible and to develop a latch that would secure the hatch covers tightly but still enable them to be removed easily. This is what I came up with:
The hatch covers were made from the pieces cut out to make the access hole, with a 40mm frame piece glued on. The forward face of this frame will have a rubber seal made of weatherstripping applied.
The latch handles were made from scraps of mahogany with a bolt imbedded. The latch is made of pieces of oak with the center tapped for the bolt. Screwing the handles clockwise latches and tightens down the hatch cover for a watertight seal. Screwing them counterclockwise until they completely loosen allows removal of the hatch cover. Stop blocks attached to the bulkhead control when the latches stop. The latches remain attached to the hatch cover and they can be easily replaced when worn out.
