If you’ve spent any time on a longboard, you may have come to the conclusion that one fin is better than more. This clever item converts the best selling surfboard of all time, the $99 Costco Wavestorm, from three fins to one. This conversion allows the board to flow the way a longboard should, and ups the fun level significantly. Every surfing household needs one of these, I own three.
