Watersports board, has fin propulsion operated by rocker connected to centreboard and provided with handlebars

摘要

A rocker (3) with handlebars (4) extends through the board (1) and is rotatably connected to a centreboard (2) at the lowest point (5) of the latter. Moving the handlebars backwards and forwards moves a fin (6) made from a non-elastic material up and down, providing fin propulsion.
