RIB Dingy with aluminum bottom
Look at Aquapro from New Zealand. It is marine grade aluminum which does not corrode when scratched. I disagree with the statement regarding weight. The Aquapeo aluminum is much lighter than fiberglass, i.e. 78lbs. for an 8''6" vs. over 100lbs. for any of the fiberglass that I looked at. I can haul the Aquapro on deck by myself and it goes like the devil with 8hp.
