One embodiment of a deployable reversible camber sail system, based on a deployable shell (58) contained within a mast-sail assembly (11, 12) and supported and controlled by additional assemblies (13-15), is disclosed. The embodiment may be easily and quickly configured into the furled, feathered, port tack and starboard tack sail forms. In addition, this embodiment represents a highly efficient sail module which may be controlled by a single human operator or automated computer-based control system. Additional embodiments, utilizing assemblages of the first embodiment sail system module, are described.

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.

One embodiment of a mast-head standing rigging connection device, allowing for sail module rotation about a mast axis, is disclosed. The embodiment allows for connection of shrouds and conventional single mast forestay and backstay rigging systems. Additional embodiments, utilizing modifications of the first embodiment, for multi-mast and triangular fore-aft sail mast roller reef-furl systems, are described.

A silencing device for an in-mast furling system is used to prevent contact between the furling extrusion and the interior wall of the hollow mast when a mainsail has been removed (such as for winter storage). The silencing device is hoisted onto the hollow mast and furled (or placed) onto the extrusion after the mainsail has been removed. In one configuration, the silencing device comprises a padding of several feet in length that is wrapped in sailcloth. The padding thus covers the extrusion and functions to limit the movement of the extrusion within the mast, eliminating contact between a bare extrusion and the interior of the mast, and significantly reducing the potential of fatigue failure for the extrusion itself.

A marine gangway has a tower adapted for attachment to a marine structure, rotatably about a tower rotational axis extending in a longitudinal direction of the tower. The tower has a tower aperture and at least one tower doorway arranged below and/or above the tower aperture where the tower aperture and the at least one tower doorway is adapted for people and/or goods to pass through. The marine gangway includes a gangway device comprising a gangway platform attached to the tower movably in the longitudinal direction of the tower, and a gangway rotatably attached to the gangway platform. The marine gangway further comprises a lift arranged inside the tower movable in the longitudinal direction of the tower. The lift has a lift doorway adapted to align with the tower aperture and with the at least one tower doorway as the lift moves in the longitudinal direction of the tower.
