The Booster has a wide diamond tail, which is perfect for boosting airs and driving hard off the bottom. This surfboard is loose and fast with an incredible amount of maneuverability. It comes with a slight single concave that blends into deeper double concaves and a small amount of "V" in the tail. This surfboard has good rail to rail smoothness and pivots sharply off the tail. The Sauritch Booster is a great summer surfboard and is really light and fast as an epoxy.
