Abstract: The wind-propelled vessel, such as a yacht or sailboard, includes a mast (10) which is slotted longitudinally on its rearmost side to accept main-sail slides (13). The mast is pivotally coupled to the vessel body by a flexible joint (9). Hounds (14) are provided facing to the rear, to accept the backstays (15,16). - Two booms (21,22) are connected at either end (by U-shaped connectors) with a jib-sail outhaul (23), and carry spreaders (25). A main-sail (29) is threaded onto the mast via slot entry points near the mast centre, while a jib-sail (34) is attached to forestays (37,38). (9pp Dwg.No.1/5) EPAB- EP-130987 B Appts. for the wind propulsion of a sailboard or like support arranged to support a user comprising: a mast arranged for pivotal connection to the board or like support by a joint means having a plurality of axes of movement, a pair of boom members laterally disposed relative to and connected abeam of the mast to have main parts extending rearwardly and forwardly of the mast and being held apart near their centre by a spreader, a main-sail secured to the mast and extending rearwardly from the mast and a jib-sail extending forwardly from the mast and means to secure the main-sail and the jib-sail between the main parts of the boom members, characterised in that, the spreader (25) is attached to the mast (10) by a loosely coupled sliding bearing surface (53) in such a way that the forward interconnection point of the booms (21,22) and that of the jib-sail forward peak and also the booms (21,22) and boom spreaders (25) at the mast interconnection point is allowed to be lifted or dropped in the same plane as that of the mast (10) and the jib-sail luffs (35) without altering the point of attachment of the jib-sail forward peak and without altering the general straight line of the booms (21,22) when sighted from the front, through the forward, mast (10), and rear interconnection points, the jib sail or force-sail (34) is secured to the mast (10) by attachment points to extend forwardly of the mast (10) so that the two jib-sail luffs (35) form a triangle at their forward peak, this peak is connected by an attachment point at the forward interconnection point of the extended boom members (21,22) to secure the jib-sail or fore-sail (34) between the pair of boom members (21,22) and both, the upper and lower luff (35) tension and sail shape are adjustable from a single control at the mast lower connection point and the mainsail passes below the booms without being penetrated by the spreader bar (25). - EP-130987 B Appts. for the wind propulsion of a sailboard or like support arranged to support a user comprising: a mast arranged for pivotal connection to the board or like support by a joint means having a plurality of axes of movement, a pair of boom members laterally disposed relative to and connected abeam of the mast to have main parts extending rearwardly and forwardly of the mast and being held apart near their centre by a spreader, a main-sail secured to the mast and extending rearwardly from the mast and a jib-sail extending forwardly from the mast and means to secure the main-sail and the jib-sail between the main parts of the boom members, characterised in that, the spreader (25) is attached to the mast (10) by a loosely coupled sliding bearing surface (53) in such a way that the forward interconnection point of the booms (21,22) and that of the jib-sail forward peak and also the booms (21,22) and boom spreaders (25) at the mast interconnection point is allowed to be lifted or dropped in the same plane as that of the mast (10) and the jib-sail luffs (35) without altering the point of attachment of the jib-sail forward peak and without altering the general straight line of the booms (21,22) when sighted from the front, through the forward, mast (10), and rear interconnection points, the jib sail or force-sail (34) is secured to the mast (10) by attachment points to extend forwardly of the mast (10) so that the two jib-sail luffs (35) form a triangle at their forward peak, this peak is connected by an attachment point at the forward interconnection point of the extended boom members (21,22) to secure the jib-sail or fore-sail (34) between the pair of boom members (21,22) and both, the upper and lower luff (35) tension and sail shape are adjustable from a single control at the mast lower connection point and the mainsail passes below the booms without being penetrated by the spreader bar (25).
