A boring day with no surf so what to do... compared the old hokua to my newish creek. lining them upside down the only noticeable difference is the obvious massive rocker on the hokua, the channels on the creek which means the fins are placed more into the middle of the board and the hokua has a double concave running through the middle.... one starts to consider what impact would it have on the creek if you had a double concave running through the board ???? Is this what gives the hokua that amazing looseness???
