Semi-Gun:

These boards take the rocker and bottom contours from their big brothers, the full Guns. The width is adapted to slightly slower, fatter surf than your full-on reef barrel. Added width helps paddling and also makes turning easier. These boards are versatile, able to surf good size Blacks or Rincon and should be the next step up when your shortboard isn't going to handle. Order these 4 to 6 inches bigger than your everyday shortboard.
