| 摘要 |
The invention relates to a device making it possible to lift up a sailboard (not shown on this drawing). It consists of a conventional aileron 2 which solely allows the heading to be conserved, to which a depth regulator 3 is fitted which, at a certain speed, lifts up the sailboard so as to decrease the contact surface between the sailboard and the surface of the water, this causing a gain in speed. <IMAGE>
