The best I have come up with is a V shaped wood platform that rests on the interior edge of the strakes about 6"-8" off the floor. The platform is made from 3/4" X 1" wood lath screwed together. It is pushed all the way to the bow with the back of the platform about 1' or so from the bulkhead. This allows me to put fish boxes on top and store ropes, fenders, tools, spare prop, etc. underneath. I also have a house battery between the platform and the bulkhead. To keep it from rattling around, I used small bungees to hold it down.
