You could try to do what they do on my oceancraft all
aluminum dinghy.... it's an 8 inch deep x 3 inch thick foam 'board' that runs the length of the craft, sewn inside heavy duty white
canvas material attached at the top. It can be flipped down for
fender use, flipped up to give extra protection from spray, or flopped all the way over the top to cushion the
dinghy when stored upside down on the foredeck.... They
work absolutely great and between them and the hard dinghy, you can go where others fear to tread
