Hi Guys,

I built a sailbox for my trailor a few years ago... 1987' I think ... still have it. Skin over frame w/ tongue& groove/daddo construction, WEST EPOXY. I would use Marine Grade plywood ($$$$). My lid slides off to the rear for two reasons: clearence/max box size and solid top doesn't LEAK !!! Everyone with a two piece top eventually leaks. I built it this way to minimize wiegh to towed (think beach). It is 28"w x 14"t X 10'lg. In my younger days I could pick it up (empty), but now I'm old and feeble .... Oh ya, I could WALK on the lid, I reinforced it with a latice work grid on the inside. Real handy for rigging/derigging mast on trailor.

Have to go no more time tonight, will answer question later Ok??
