Generally this is how to pick your race board:
1) Displacement (round bottom) hulls beat planing (flat bottom) hulls in flat water circuit races.
2) Longer boards are faster than shorter boards
3) Planing (flat bottom) hulls beat displacement (round bottom) hulls where planing is possible. Planing is only possible with wind or swell at your back. You cannot put a board on a plane with human power alone
So choose your style of fun. These boards are planing hulls designed for ocean down-winding.
