I think all aluminum superjet / standup .would be like a flat bottom boat in the surf .that thing would beat the tar pizz out of u..I would say u would have to ride on a clam day with no chop at all ..plus I would all so think it would vibrate real bad as well ..I have ridden in plenty of aluminum boats and they will smack the water hard ..but it would be cool as hell if someone made a standup ...I have seen a wetbike that was all aluminum ..it was on wetbike.net ..I think the dudes name was tori
