Construction set for converting a windsurfing board into a trimaran-like vessel

摘要

In order to make a windsurfing board more versatile, a collapsing or folding seat, in combination with one or more outriggers, with or without rudder, and a commercially available sail or a sail of novel design, is to be attached without mechanical modifications to commercially available windsurfers. During transport, the construction set is transported like a suitcase on the surfboard or is transported separately.
