A wind generator for sailboats including a mast (A) provided with crosstrees (C), including: at least one wind generator (1) provided with a distribution of blades (2) arranged to rotate integrally with a shaft (6) of axis (a) in response to receiving a wind flow in an active direction (v) incident to the blades distribution; an electric generator (3) operatively connected to the generator (1) for converting the rotation of the blades (2) into electricity, comprising structure (22, 41) for fixing the generator (1) to a crosstree (C), and with the blades (2) being movable from an open operating position (P1) of maximum incidence of wind flow (F) to a closed non-operating position (P2) of minimum obstruction.

A nestable wing sail having two or more sections. Where one section is configured to nest inside the first section, and can move out of the first section to extend the effective sail area of the wing sail.

Disclosed is a mast intended to equip a marine or submarine vessel. The mast includes a metal structure extending along an axis and a fairing arranged externally to the structure in a direction normal to the axis. The fairing is removably assembled to the structure.

A multihull sailing vessel includes at least two buoyant hulls extending along their longitudinal axes, with the hulls being connected to each other and a first hydrofoil connected to the hulls and oriented transverse to the hulls. The first hydrofoil is movably coupled to the hulls between a first position above a resting waterline of the hulls and a second position below a lowest extent of the hulls. When the first hydrofoil is in the second position, a configuration of the first hydrofoil is adjustable to vary an amount of lifting force generated by the first hydrofoil when the hulls move forward through water when the first hydrofoil is in the second position.

An exemplary windshield assembly for a marine vessel includes a plurality of first extrusions arranged vertically; a plurality of second extrusions, wherein each second extrusion is a crossbar arranged between a pair of first extrusions; and an opening formed between each pair of second extrusions connected between a common pair of first extrusions, wherein each opening includes a plurality of receivers formed for framing a panel, the plurality of receivers formed on a surface of each first extrusion and each second extrusion of a respective opening, and wherein a front opening includes an upper second extrusion and movable front panel, the movable front panel being connected to rotate about the upper second extrusion for venting.

The device disclosed herein is for a folding mast device for use on watercraft. In the preferred embodiment, the mast is used on a bridge erection boat; however, additional watercraft may also incorporate this device. The mast includes clamps and other components in order to allow the mast to be assembled and disassembled without tools, which also makes the assembly and disassembly quick. The mast is also quickly removable and replaceable. The mast also can incorporate safety features, such as lighting and other devices needed for safe navigation, and is capable of adjusting to accommodate fabrication differences.

A catamaran having two parallel symmetrical hulls of equal size spaced apart with a superstructure lower deck extending from an outer edge of the first hull to an outer edge of the second hull. The lower deck is positioned above the static waterline and provides a single, constant, flush elevation height across the entire length and breadth of the vessel, with the placement of control and propulsion machinery in the hulls. The improved catamaran has an increased freeboard, increased gross tonnage, and decreased design pressures on the superstructure scantlings of the catamaran deck as compared to a conventional catamaran having a lower deck mounted beneath the static waterline, or accommodations added to the hulls.

A wind-propelled vessel is described herein. The vessel includes at least one hull and at least one set of paired masts. Each paired mast of the at least one set of paired masts has a first mast located to one side of the vessel and a second mast located on the opposite side of the vessel. Also, each mast of the at least one set of paired masts has a spar located at or near the top of the mast. Moreover, each one of the spar located at or near the top of the mast extends inwards towards a center plane of the vessel, and an inward end of the spar is connected by a connector to another inward end of another one of the each one of the spar located at or near the top of the mast. In accordance with the illustrative examples provided herein, the connector imparts a dynamic force upon connected spars that responsively pulls the connected ones of the inward ends of the spars to their nearest position when tops of the masts to which the spars are fixably attached move away from a relative nearest position to a paired one of one set of paired masts.
