A second seat locker
I'm not sure the configuration is the same, but I have a '77 H-30, with a cockpit seat locker on starboard, and what used to be a quarter (pipe) berth under the port cockpit seat. The previous owner simply sawed out a huge seat locker lid, incorporating the seat back also, and installed a piano hinge right about shoulder blade high. I have to say that he (or she) did a good job of modifying the interior. There is a wooden bulkhead, with a fine teak cabinet that sits on the inside end of the old quarter berth. Probably tripled the galley storage area. The seat locker now holds the water heater, the battery charger and all kinds of other stuff. When I bought the boat, there were two buckets in the locker designed to catch the water that obviously flowed right down the cracks. I used foam tape for a better seal, and am now in the process of beginning to think about working on a design to make the crack self draining, similar to the starboard side locker. The thing is, such a huge seat locker lid makes for very easy access to the tanks and the engine and etc. To create the drain I'll necesarily have to restrict that somewhat by creating a lip underneath that drains athwartships into the cockpit floor.Unfortunately I'm a few miles away from my boat, so I can't post a picture just yet, but give me just a few weeks and I'll try.
