Benefits of technology

[0013] The aim of the present invention is to provide a novel operation principle, in particular to properly adjust a bow sail, such as the jib and preferably the genoa.

Problems solved by technology

The Spinnaker is used in an aft wind or stern wind condition, but it cannot be used with the sail close to the wind.
In a sail close to a wind condition, the sailboat “jams” the wind.

Embodiment Construction

[0023] With reference to the number references of the above mentioned figures, the nautical device according to the invention, which has been generally indicated by the reference number 1, comprises a bearing supporting element 2, in the form of a cross, preferably made of a boxed steel material or light alloy and mounted at the bow 3 of a boat 4.

[0024] Said cross supporting element 2 is advantageously mounted by bottom supports 5, made of a steel material, for reinforcing said cross supporting element 2 and for attaching it to the bow 3 of the boat 4.

[0025] The device comprises, moreover, a steel rail 6, in the form of an arbalest or leaf-spring.

[0026] The rail 6 has a bending radius corresponding to the distance between the boat mast 7 and the attachment 8 of the hook member of the bow sail 9, comprising either a jib or a geona.

[0027] The bow sail is in turn coupled to a carriage 10, which may slide in said rail 6.

[0028] Said carriage 10 is driven along the rail 6 by a drivin...

Abstract

A nautical device, for adjusting the bow sail of a sail boat comprises a cross-shape support element including a support rail, therealong a carriage to which the bow sail is attached slides. The device comprises moreover driving and locking means for driving and locking the carriage to/at a desired position on the rail. The device allows, by driving the carriage to which the sail hook is attached, to modify the angle of incidence of the sail, with respect to the wind, as the sail boat is driven with the sail close to the wind, to always hold the same angle of incidence of the wind on the sail, and jam the direction of the sail boat toward the wind, to substantially achieve an upwind condition, to remove the sail from the spanker (with a butterfly type of sail), thereby increasing the surface of the sail thereon the wind incides (like a Spinnaker).

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a nautical device, specifically designed for adjusting the bow sail of a sail boat, such as the jib or preferably the genoa sail. [0002] As is known, the jib and genoa sails are triangular sails which are raised before the forward mast. [0003] The jib is usually directly anchored on the boat deck by one or two stays which are generally extended for a comparatively large extension abaft the mast. [0004] The genoa, or Genova, is a jib of a large size hoisted on the forward stay, with a very low foot, and it can also be applied with the sail close to the wind. [0005] Another bow sail is the so-called Spinnaker, which is substantially a large size jib having an isosceles triangle configuration, which is hoisted by a halyard passing through a pulley arranged at a top of the inner stay, and, sometime, even on the head of the mast. [0006] One of the clues is clamped to a rod, the swinging boom, and is ejected from the part...
