Inclined aileron for water surf board is positioned near hull edge and directed outwards, aileron plane defined by perpendicular intersection between aileron intrados longitudinal and transverse axes

摘要

The surf board (1) has two ailerons (2) each positioned near the edge of the hull and directed outwards from the board. The hull plane is defined by the perpendicular intersection between the longitudinal axis (5) and the transverse axis (6). The aileron plane is defined by the perpendicular intersection between the longitudinal axis (4) and a transverse axis of the aileron intrados.
