Booster for becalmed surfboards and windsurfing boards

摘要

The booster is a drive means for surfboards (7) in the absence of wind. This drive means consists of an energy source (1), a motor (2), a driveshaft (3) and a propeller or air screw (4). The booster allows the surfer to propel his surfboard forwards in the absence of wind and on a calm surface without physical driving efforts on his own part. IMAGE
