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 connector cover is proposed that protects the web loop portion of a foresail from exposure to UV radiation. The connector cover is formed of UV-resistant material and is configured to include a tab portion that passes through the shackle and a shroud portion that wraps around the tab and web loop in a manner that maintains the cover in place. Various hook-and-loop fasteners can be used to fix the connector cover in place, as well as external ties, cording, or any other suitable type of releasable fasteners. Advantageously, the connector cover is configured to remain in place and provide protection, but is also easy to remove and replace as necessary.

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 sail includes at least three sides, namely two longitudinal sides respectively called luff and leach, as well as a lower transverse side called foot consisting of an assembly of panels having transverse edges parallel to the foot and longitudinal edges parallel to the luff and the leach, each panel being hinged to the adjoining panel around an axis parallel to the foot. Each of the panels includes reinforcing elements distributed into the two following groups: (a) a first group in which they extend parallel and in proximity to said transverse edges, and (b) a second group in which they extend parallel and in proximity to the longitudinal edges of the panel. They are connected two by two by connection parts in the continuation of the reinforcing elements of the second group, so that the forces assumed by the reinforcing elements are transmitted longitudinally from one panel to another.
