Commercial ship equipped with a duplex rigging

La présente invention concerne un dispositif dénommé navire commercial équipé d'un gréement duplex permettant d'utiliser l'énergie éolienne en tant que force motrice du navire. La particularité de ce dispositif est d'utiliser un gréement constitué de mâts solidaires en position jumelée, chaque mât étant placé sur les côtés de la coque au lieu de la position classique centrale, un navire pouvant contenir plusieurs couples de mâts duplex. Cette disposition des mâts présente plusieurs avantages, dont celui de réduire l'emprise des mâts sur la structure, celui de laisser un espace optimal au chargement, celui d'offrir une meilleure emprise au vent, celui de réduire le gîte, et celui de positionner les mâts en des points structuraux très robustes. Un haubanage transversal et longitudinal assorti d'entretoises robustes entre les mâts duplex assure une très grande robustesse à l'ensemble. Optionnellement, grâce au haubanage garantissant l'assise mécanique du gréement, les mâts peuvent être à la base montés sur des articulations permettant un démontage ou un basculement facilitant la maintenance et la navigation en zone à faible tirant d'air (fleuves, embouchures, voies maritimes...).

BIPLANE SAILING RIG

DEVICE FOR ORIENTABLE BIPLAN

L'invention concerne un dispositif pour gréement biplan orientable pour la propulsion vélique d'un véhicule. La configuration « biplan » pour la propulsion vélique d'un véhicule est confronté au problème de la perte d'efficacité du plan sous le vent, lorsque l'orientation du vent apparent fait que le plan sous le vent se trouve dans les turbulences générées par le plan au vent. Pour pallier à ce problème, l'invention consiste en un dispositif qui permette la rotation du gréement biplan, de manière à pouvoir l'orienter de façon optimale quelque soit la direction du vent apparent par rapport au véhicule. En référence à la figure pour l'abrégé (figure 1), ce dispositif est constitué des principaux éléments suivants : une base (1) conçue pour reprendre les efforts du gréement et pour pouvoir pivoter autour d'un axe vertical, deux mâts (2) en appui sur la base, une barre de flèche (3) reliant les mâts, quatre haubans (4) reliant les mâts et la base de façon rendre l'ensemble géométriquement stable, les organes de contrôle (5) des éléments mobiles du gréement et de la voilure. Le dispositif selon l'invention est particulièrement destiné aux bateaux à voile. The invention relates to a biplane orientable rigging device for the propulsion of a vehicle.

Patent FR2323574B3

Sailing boat hull lift device - has inclined lateral floats with aerofoil cross section mounted at bow and stern

The sailing boat has side floats which progressively lift the hull from the water and reduce the suction effect. One pair of floats is at the front, mounted on an outrigger (10), the second pair being at the rear. Each float (20, 22, 24, 26) is of hollow construction for lift and has an aerofoil horizontal cross section. Its vertical cross-section tapers to the bottom tip and may be straight (24, 26) or curving inwards (20, 22) towards the keel. All floats are mounted at an angle (F) to the vertical and provided with a worm and screw mechanism (44, 46, 48, 50) to alter the angle of incidence.

Masts and spars device for improving the sails on a sail boat

The invention relates to a masts and spars device, distributing and balancing tensions of the sails between tripod and main mast. It is composed of 3 masts C I J, in a pyramid-shaped tripod, securely fastened to a system of sleeves E A' B' C' sliding on masts connected by sandow springs D S O Q G H. When a wind tension is created on the sails, an antagonistic force of the device tends to bring the front sail towards the initial position. This front sail SPI etc., supported by the tripod, moves to relieve the main mast F which supports the main sail. Two small booms T U, fitted on the lateral masts I J, support two additional triangular sails. A ''double shock-absorber'' system B attenuates the jolts towards the prow. The device, according to the invention, is intended for industrial sail boats, pleasure boats and racing yachts.

Sailing ship

A sailing ship (1) has at least one mast (2,3,4) rigidly attached thereto, to which the yards (5 to 9) are rotatably attached. By an actuating shaft (21), the sail (22, 22a, 22b) can be reefed and, with the aid of a corresponding rope (24), it can be erected or stretched. The sail (22, 22a, 22b) is narrower in the middle than at the edges and has upper and lower boltropes (48, 49) that are guided in grooves (27) to the yards (5-9). Erecting and reefing of the sail (22, 22a, 22b) and bracing can be accomplished by remote control. Because of the high speed that can be attained, energy recovery is possible with a propeller.

Mast foot arrangement

Catamaran with adjustable sails - allows mast, rigging and sails to be moved from one hull to other to suit wind

The sailing boat with a catamaran hull has a single mast which can be moved from one hull to the other, complete with all the rigging and sails. This permits an increased sail area to be used, as the sails are altered in this way to suit the direction of the wind, giving greater stability. The stays which support the rigging from a pentagon and adjust themselves accordingly to the tack. The whole system can be transferred simultaneously single handed. Rigging weights can be positioned quickly, and the dew of the jib does not alter for any tack. The system enables the size of the vessel to be reduced. The sails do not need to be reduced immediately the wind changes.

Fast self righting catamaran

This highly engineered recreational catamaran features a unique pivotable mast with a downward extending section that holds an underwater ballast. A hang glider type sail provides lift as well as thrust. Working in combination with the underwater ballast, the sail functions to deliver a high performance sailboat with high stability and ease of control. The ballast also aids in righting a capsized boat. Advanced three tier hydrolift type pontoons raise the boat partially out of the water under full sail thereby minimizing drag and maximizing speed. A convex deck and optional convex cabin facilitate righting an overturned boat. Other advanced features include retractable daggerboards for turning control, telescoping lower mast for shallow water sailing and beaching, underwater battery powered propulsion for movement in a calm wind and power assisted winches for sail lift and turning control.

Rigging for sailboats

The rigging which enables doubling the lift polygon comprises two pivoted porticos (11). These are constituted by uprights (2) fixed to floats (10) and spars (3). Two parallel masts (4) are fixed vertically to the middle of the spars and held suspended apart by the yards (5) and eight shrouds (6). The floats incline simultaneously by the same degree as the uprights, which are driven by the spars fixed to the masts, as soon as one of the two sheets (8) is tacked. The two floats are pivoted by spindles at the four corners of the deck and have an inclination equal to that of the uprights.

IMPLANTING RACE OR CRUISE SHIP

The invention concerns a competition or cruiser sailboat comprising a hull (1) closed by deck (2), and wherein is implanted the lower end of a mast (4) bearing the rigging, characterised in that the mast (4) is a tilting mast without side stays, mounted pivoting in particular on bearings about a substantially horizontal axis (x-x') of the hull (1) such that, whatever the weather conditions, its centre of gravity (G) can be placed in the wind, in the sailboat centre of rotation, and the rigging plane perpendicular to the air streams.

High speed sailing device

A sailing device comprising a hull structure (1), a fin structure (2) and a sail system (3). The sail system (3) is arranged to be trimmed with its foot portion (4) to leeward of its upper portion (5) and for generating a wind resultant force including an upward lift component. The fin structure (2) is adapted for generating a lift having a downward component. During sailing in stronger winds, the downward component of the lift generated by the fin structure opposes the upward lift component of the wind resultant force, enabling to carry sails generating an upward lift component larger than the gravity forces exerted onto the device, without the device being lifted out of the water. Thus a substantially improved driving force to water displacement ratio can be achieved, so in principle higher speeds can be achieved than with known sailing device.

A bottom end of the rigid stay is fixed towards front of a hull, where the tower and the rigid stay are fixed to chain plates of the hull.
