The present disclosure is directed generally toward sailing vessels. One example is a catamaran with one or more pivoting masts per hull member, which may pivot from a generally perpendicular upright position, to a generally flat stowed position toward the bow of the hulls. The masts are capable of sustaining a plurality of sails, which may travel 180 degrees with respect to the hulls.

A system for autonomous ocean data collection includes at least one sensor capable of collecting sensor data, at least one transmission device, and at least one computing device comprising one or more hardware processors and memory coupled to the one or more hardware processors, the memory storing one or more instructions which, when executed by the one or more hardware processors, cause the at least one computing device to generate data for transmission based on the sensor data collected by the at least one sensor, and cause the at least one transmission device to transmit the data.

A ship-mounted auxiliary sail system featuring a plurality of sail units mountable and movable about the ship on a rail system. The sail units can have automatic reefing safety features and/or automatic mast release safety features.

A traction system for a watercraft, including a sail and a fixed station that includes a mast and a winch which is connected to the sail by a traction cable, the system further including a bottom part that is supported by the traction cable, and fold lines, each of which has an end that is attached to a leading edge of the sail, and another end that is supported by the bottom part. The fixed station includes a base that accommodates the bottom element when the sail is retracted by the winch; and structure for grasping each fold line and pulling same towards the mast so as to retract the leading edge against the mast and fold the sail once the winch has retracted same close to the station.

The present invention refers to a new multilayered material, reinforced with fibres and having an improved adhesion between the layers throughout its entire structure; to a process for its preparation and to the articles made with such material, intended to be exposed to adverse conditions, such as strong winds, stretching, temperature changes, such as for example sails for boat.

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 physically-impaired-assisting multi-function sail comprises: a stanchion, a hoisting navigator for allowing an arthritic to deploy and retract the sail without the need to bend the fingers, a hoisting teeter totter secured to the navigator, a teeter-totter hook-lock secured to the teeter totter for automatically locking and unlocking the teeter totter to deploy and retract the sail, a cable secured to a camber, a cable canal formed into the teeter totter for hiding and protecting the cable within, a pivoting pulley housing secured to the teeter totter, a pivoting pulley hub swingingly attached to the pivoting pulley housing, sail-buttresses hingedly attached to the pivoting pulley hub, a sail canopy secured to the sail-buttresses, multiple cable pulleys rotatably secured at multiple locations within the pivoting pulley housing and pivoting pulley hub, a central tube attached to the pivoting pulley hub, sail-buttress-supporting arms hingedly attached to the sail-buttresses, and a shuttling hub attached to the sail-buttress-supporting arms.
