Sure. Here are the pix. Know that:
1. This was supposed to be a prototype. Six or seven years ago. Maybe I'll get around to making the "real" hatch one day.
2. I used marine plywood from Lowe's. Since then, local boat hobbyists have told me the wood is obviously fir, and not what a real boatbuilder would use. Apparently the only professional grade marine plywood on the west coast comes from a single plant in Tacoma, WA. The locals said that for a hatch, I might get better results from using top-grade exterior construction plywood. (After all, the hatch doesn't have any more water contact that the shutters on a house. At least, as long as boat is right side up.)
3. I varnished the hatch originally. Now I would use West epoxy with its clear hardener. Then varnish over for UV protection.
4. The hatch itself is 1/4" thick and the rim that fits inside the cuddy opening is 1/2", and there is an extra piece supporting each of the three dogs, plus another flange that fits over the bottom lip of the opening, making the whole monster unreasonably heavy. Note the pathetic lightening holes drilled in the inner surface.
5. The lower corner is a weak point. The bulkhead is somewhat convex, so the hatch is tight on top, but springs away from the bulkhead at the bottom. Hence that big lip. Note the small photo of the corner. The hatch tape goes from sealing the inside surface of the hatch to sealing the bottom surface of the rim. I have not found a way to do that transition and make it last all summer. You can see that the upper piece of tape has torn away from the joint, leaving an unsealed space.
6. The latches come from Marine Parts Depot. They turn to fasten against small oak blocks inside the bulkhead. Those are held in place with glue and the same screws that anchor my Barber lead cleats (see earlier cockpit picture). Speaking of which, the things hanging on the hatch in that photo are a solar charger (removed when underway) and the bag that holds my halyard tails.
7. I think a better way to make a hatch would be to bend a thin sheet of plywood to the exact profile of the bulkhead, then reinforce it with strategically placed hardwood strips, avoiding the massive thickness of the inner rim. Add two more latches on the lower surface. Use a continuous foam tape on the inside surface, joining the ends with silicone. Factory hatches on newer Day Sailers hinge at the top, but I wanted to be able to take the thing completely off in gentle weather when we don't need it.
