Mega Hatch
I turned it around and accordion-hinged it as seen in other mod pics. I use the same plug as for the livewell in the mega hatch hole. I added a spring to hold up the cover but drilled the top connection and added a pin instead of rivet (so that the whole hatch could be opened if needed ever). I added a cooler for dry storage, secured by general purpose brackets I found at West Marine (but I do find myself being very careful not to smash my fingers when pushing the handles into the brackets...).
