I have decided to build my own flush hatches and hatch covers instead of the Bomar hatch covers specified in the plans.
They are self bailing and drain into the cockpit. I have included a couple of pictures and a quick description for anyone who might be interested. They are easy to construct on the pocketship because of the way it is framed according to plan. Carefully cut out a hole the size of the specified Bomar cutout, or you can make it any size not to exceed the width of the already existing frames. frame it out with 3/4 X 1 timber on 3 sides, one side is already framed, build a channel with 2 inch wide 9mm ply, stiffen the joints from underneath with butt blocks at the corners and complete the channel with 1/2 X 1 timber on the inside edges. This will leave a 3/4 inch channel for drainage all the way around . Drill 1/2 inch holes at the corners of the channel leading into the cockpit. Coat everything with lots of epoxy.
The cutouts can be used for the lids and they will be laminated around the bottom edges with 1/2 inch wide 9mm ply, then leave a 1 inch space for a thin sealing strip all the way around and then laminate the rest of the bottom of the lid with 9mm ply.
The lid will be finished of with perko adjustable latches and SS hinges.
