摘要:
A wind powered craft carrying a generally vertical mast which is rotatable about its vertical axis, having a sail carried by the mast with its bottom edge attached in proximity to the bottom of the mast and extending to an attachment point in proximity to the top of the mast. A generally horseshoe-shaped member having an open end is and extending around said mast. The mast being rotatable within the horseshoe-shaped member. A bearing supported stationary member at the top of the mast is carried by the mast while allowing the mast to rotate. A support stay runs from the horseshoe-shaped member to the bearing supported member to support the horseshoe-shaped member. Additional stays are attached to the horseshoe-shaped member and splayed to attach to opposed sides of the hull of the watercraft. The sail is reefed around the mast through the open end of the horseshoe-shaped member.

Bei einer Anordnung mit einem Profilmast zur Aufnahme eines Rollreffs ist vorgesehen, diesen mit seinem Mastfuß zwischen Deck- und Kielbereich des Schiffes drehbar einzuspannen. Der Profilkörper ist dabei im vorderen Bereich durch Holme als biegesteifer Träger ausgebildet, während der hintere Bereich als Aufnahmekammer durch Wandungsteile mit elastischen Bereichen gebildet ist und eine Schlitzöffnung zum Austritt des Segels durch Endleisten begrenzt wird, die elastisch federnd gegeneinander preßbar sind.

A sail support and control system designed for use as sail assist propulsion on a cargo vessel. The system provides complete powered control of the amount of exposed sail, the angle of the sail in relation to the vessel, and clew outhaul and downhaul tension so that no manual handling of rigging is required. An unstayed mast is rotatably mounted on the ship to enable furling and unfurling of the sail by mast rotation. A cantilever boom is mounted on the mast support so as to be horizontally rotatable thereon. Boom positioning winch means is mounted on the boom to pay out and take in sheet lines, which are dead ended on the deck, for swinging the boom to a desired angular position in relation to the ship and maintaining it in said position. Means is provided for rotating the mast in relation to the boom so that the sail may be reefed without changing the position of the boom, and so that swinging of the boom also causes a corresponding rotation of the mast. A change in position of the boom does not, therefore, change the amount of exposed sail. Tension on the clew of the sail is provided by an outhaul and a downhaul which operate independently of each other. An outhaul tension line is payed out and taken in under continuous tension in conjunction with the rotation of the mast to take in or let out sail. The downhaul mechanism is mounted on the boom and connected to the clew, and travels in and out along the boom with movement of the clew, maintaining a continuous downhaul tension during such movement. All motions of components and tensions on lines are preferably provided by hydraulic motors or cylinders controllable from the bridge, so that the manual handling of the rigging is required.

The invention provides a sail for a wind powered craft and comprises a sail having a luff and being formed from overlapping first and second sail panels (5) joined at or adjacent their leech edges and together forming a sail leech (7). A plurality of battens (2) are located between the first and second sail panels and extend at least partially between the sail leech and the sail luff. Means (105, 108) are provided to apply a load on the battens to force at least some of them to adopt or increase a curved profile and thereby impart a correspondingly curved profile to either the first or the second sail panel. The battens can be moved from one sail panel to bear upon the other sail panel to enable the sail to be tacked. The inversion also provides a sail arrangement with such a sail and a mast, as also a vehicle including such a sail or sail arrangement.

A wing profile sail is in the form of a sailcloth which defines an airfoil-shaped space, which is filled with air through openings or one-way closing mechanisms. At the sail's luff (1) there is provided a bag/lung-shaped body which can be filled with air and which is extendible in the height direction and which in an extended state forms an upwardly tapering conical, cylindrical body (11). The sail's outer cloth (2, 3) extends from this body (11) and is transferred on each side from this body (11) and is attached at a distance from the after leech (7), the sail's after part (7) being composed of one sailcloth surface. From the outer sailcloth's (2, 3) attachment area, in the inner spaces of the sail there is provided an intermediate sailcloth, which at least covers the area of the openings for air supply. The outer sailcloths (2, 3) are connected in the sail's bottom area in order to form the inner spaces in such a manner that the outer sailcloths are movable in relation to each other.

Device for propelling ships consisting of one or more isoceles triangle shaped-sails (5), reinforced by mesh, The sails are formed by the upper end of large masts (2) and the ends of long yards (3) at the lower part. These yards are in line with the longitudinal axis of the ship, or folded up vertically next to the mast when not in use.
