Abstract: The present invention relates broadly to a rigid wing (10) which in its preferred embodiment is a rigid wing sail fitted to a water-borne vessel. The rigid wing sail (10) comprises a pair of elongate rigid panels (12A) and (12B), and a hinge element designated generally as (14) coupled to the panels (12/B) to permit pivotal movement of the panels (12A/B) relative to one another. Each of the pair of panels such as (12A) includes an adjoining edge (16A) and an opposing lateral edge (18A). The hinge element (14) is coupled to the panels (12A/B) at the respective adjoining edges (16A/B) to form either: 1) a closed configuration of the wing (10) with lateral edges (18A/B) of respective panels (12A/B) positioned adjacent one another wherein the rigid wing sail (10) is closed; or 2) an open configuration of the wing (10) with the lateral edges (18A/B) of the respective panels (12A/B) separated from one another wherein the rigid wing sail (10) is set at a variable camber.

Abstract: A pedestal (1) for a sailing boat comprises a casing (2) and inside such a casing (2): at least one driving wheel (11a, 11b) associated with a motion input shaft (3), at least one driven wheel (12a, 12b) associated with a motion output shaft (4) and at least one motion transmission element (13a, 13b) from said at least one driving wheel (11a, 11b) to said at least one driven wheel (12a, 12b). The pedestal (1) further comprises, also inside the casing (2), a speed variation system selectively activatable to vary the rotation speed of the motion output shaft (4) with respect to that of the motion input shaft (3).
