A portable sail for use with a paddle and paddle board, where one edge of the sail has a fastening portion that is reversibly affixed along the length of the paddle, while the opposite end of the sail is held by the user via a cord or handle. With paddle held upright on the surface of the paddle board with one hand, and controlling the end of the sail with the other hand, a user can capture the wind and propel the paddle board through the water. The rate of propulsion can be adjusted by partially wrapping the sail around the paddle to reduce the sail area exposed to the wind. Furthermore, the sail can be entirely wrapped around the paddle so the paddle can be used to manually propel the paddle board in the traditional manner.

The invention relates to a sailing rig system (SRS) for a sailing ship comprising one or more airfoil sails comprising one or more sail defining frames including at least three airfoil sail shape-defining edges and/or at least three airfoil sail shape-defining corners. The sail may be controllable, rotatable, pivotable, trimmable, reefable, stowable, slidable, windable, guidable, coaxial, weathervaning, wind/sun tracking, freestanding; it may provide cambering, reinforcing, sealing, boundary layer control, shielding means, sections and connections and it may be transparent. The frame may be a closable/deployable rotor sail frame. The frame may include rig components and the SRS may further comprise vertical/oblique/horizontal spars coupled with spar couplings. It may further comprise lateral, fore-and-aft, superposed sails, actuators, power generators, power sources, thermal management systems, defined rotor sails. It may provide sail twist. It may be coupled with a sailing ship with defined ship couplings. A sailing method is proposed.

A handle for winches includes an arm with a main longitudinal extension having longitudinally opposing ends, a first end and a second end, respectively, on which there are mounted a coupling member for connection to a winch and a grip, respectively. The coupling member and grip extend from a transversely opposite first face and second face, respectively, of said arm. The handle includes at least one lighting device which can be selectively activated, mounted on the arm in an intermediate position between the Longitudinally opposing ends and orientated to project at least one lighting beam from the first face.
