A rigging comprises a mast controllably about a longitudinal axis; a flexible sail comprising a starboard and port flexible sail portions; a plurality of elongated battens which extend a luff and a leach of sail portions; each batten is pivotally connected to a respective outermost part of the respective side of the mast. Rotation of the mast causes the battens connected to one of the sail portions to be compressed along their length and causes the battens connected of the other sail portions to be tensioned along their length so as to change the shape of an aerofoil formed by the sail.

There is disclosed a sail for producing propulsive power or lift in a fluid, where the sail comprises a first layer and a second layer where the first layer and the second layer are connected along at least one corresponding side, and the first layer and the second layer define a cross-sectional shape of the sail substantially perpendicular to a longitudinal direction of the sail. The shape of the first layer is adjustable and/or the shape of the second layer is adjustable such that the cross-sectional shape of the sail is adjustable. There is also disclosed a vessel or a sailboat comprising such a sail.

A rigging for a wind-propelled vessel includes: a rotating airfoil-shaped mast; a sail movably coupled to a trailing edge of the airfoil-shaped mast and configured to be hoisted or lowered along the airfoil-shaped mast; a swiveling masthead coupled to a top section of the airfoil-shaped mast; and a plurality of stays supporting the airfoil-shaped mast, each stay having a first end connected to the swiveling masthead and a second end connected to a hull of the vessel.

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.
