Definitions

  • the invention relates to an apparatus for the wind propulsion of a sail-board or like support arranged to support a user comprising a mast arranged forthe pivotal connection of 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.
  • This invention particulary relates to certain improvements in sail plan and rigging of wind propelled apparatus such as surfboards, sail-boards, small yachts, canoes, boats, sail boats, multi-hull boats, ice-boats, skateboards, sleds and wind propelled land vehicles of the type that use sail attachments, masts and rigging that are dependant upon a pair of boom members laterally disposed and accurately connected athwart to that mast and securing a main-sail therebetween.
  • wind propelled apparatus such as surfboards, sail-boards, small yachts, canoes, boats, sail boats, multi-hull boats, ice-boats, skateboards, sleds and wind propelled land vehicles of the type that use sail attachments, masts and rigging that are dependant upon a pair of boom members laterally disposed and accurately connected athwart to that mast and securing a main-sail therebetween.
  • the aerodynamic slot between the two sails improves air flow, reduces turbulance and drag, and lowers the stalling point of the main-sail.
  • the jib-sail has less turbulance at its luff than the main- sail and takes advantage of the upwash of air flowing past the main-sail to produce added driving force, which is more forward and less sideways than the main-sail.
  • the adjustable stays, shrouds, travellers, outhauls and sheets enable more effectivity control of forestay tension, mast bend and sail shape, while the height of the connection point between the forestay and the mast may be alterned to form a frictional rig.
  • a sailboard which comprises a mast, a pair of boom members laterally disposed relative to and connected abeam of the mast, and having parts extending rearwardly and forwardly of the mast and being hold apart near their center by a spreader and having a main-sail secured to the mast and extending rearwardly from the mast end a jib-sail extending forwardly from the mast.
  • the spreader is attached to the mast by a bearing surface which is only able to rotate on the mast, and the forward parts of the jib-sail are connected to the forward peak of the boom by a bar.
  • the sail-board accordingly to the present invention is distinctive from the prior art insofar as the boom members are free displacable along the mast by the bearing surface of the sprader and insofar as the sailing power is transmitted from the upper luff to the lower luff of the jib-sail and from there to the lower halyard, which serves as a single control at the mast lower connection point, in such a way that the sail-board is easy to adjust by a single control, while sailing.
  • the use is similar to the existing apparatus, but it is easier to tune the adjustments of the jib-sail and of the main-sail in tandum to obtain optimal results dependant upon wind strength and direction, because it is now possible to adjust the apparatus from one single control at the lower connection point of the mast, while sailing without altering the point of attachment of the jib-sail forward peak and without altering the general straight line of the booms when sighted from the front, through the forward, mast and rear interconnection points, whereby the distance between the stays is adjustable to vary the shape of the jib-sail or fore-sail symetrically both above and below the booms.
  • the apparatus has a body adapted to support a user, in this case it is in the form of a fibreglass surfboard together with mast, mast-foot and fitting, twin boom members, and main-sail and attachments.
  • the board 1 is provided with a removable swing keel 2, rudder fins 3, foot straps 4, mast step 5, bow 6 and stern 7.
  • the mast fitting 8 is connected to the mast step 5 by a flexible joint 9 in the form of a polyester lanyard and retainer.
  • a mast 10 of aluminium alloy circular section tubeing is attached to the mast fitting 8 by means of suitable pop rivets 11, it is slotted lengthwise on the rearmost side to accept the main-sail nylon slides 13, hounds 14 are pop riveted top and bottom facing to the rear to accept the backstays 15 and 16 with single angles tangs 17 located at these points also on the sides to accept the shrouds 18 and vernier adjustors 19.
  • the stainless steel loo- plides 20 with tops on "T" track slides which serve as jib-travellers.
  • Two boom members 21 and 22 of aluminium alloy circular section tubeing are connected at either end by "U"-shaped connectors of moulded P.V.C. with one roller block 23 for the jib-sail outhaul and three roller blocks 24 on the rear connector for the main-sail outhaul and two backstays 15, 16.
  • These connectors are pop riveted to the booms and the jamb cleats at median points also fitted. Attachment points for the user are in the form of a foam covering 49.
  • the spreaders 25 are also constructed of aluminium alloy tubeing with circular section and welded together then pop riveted to the boom members.
  • Small chainplates 26 are attached for connection of the shrouds 18, and both the shrouds 18 and the fore 37, 38 and back stays 15, 16 are stainless steel wire with swaged thimbles 27 and shackles 28 being the means of attachment between the mast, booms and sails.
  • the boom spreader 25 is allowed to rotate about the mast but may be secured partially with a shock cord or bearing surface 53, which also allows its sliding along the mast.
  • Boom sleeves 54 are provided.
  • the main-sail 29 is fitted with nylon sail slides 13 along its luff 30 and is threaded onto the mast via the slot 12 entry points 12 near the centre of the mast from the centre outwards both up and down. It is tensioned with halyards 31 and cleats 32 at either end and by the main outhaul sheet 33 on the boom. Reefing 43 points are fitted.
  • the jib-sail 34 is fitted along its luff 35 with piston hanks 36 for easy attachment to the forestays 37, 38, fall halyards 39 and cleats 40, jib outhaul sheet 41 and cleats 42 and reefing points 43.
  • the sails are dacron fitted with batten pockets and battens 44 eyelets with reinforced sections 45, sail number 46, transparent windows 47, wind telltail 48.
  • a rig uphaul sheet 50 is provided.
  • backstays 15, 16 To enable the backstays 15, 16 to cleat they are brought through the outhaul rollers then joined together and attached to a suitable polyester sheet which then leads to the backstay jamb cleat 51 which is situated on the boom opposite the main sheet outhaul jamb cleat 52.
  • variable adjustments of stays, shrouds, halyards, and sheets produce a great number of different sail shapes to suit the user dependant upon wind and sea conditions.

Abstract

Une planche à voile ou autre petite embarcation est équipée d'un mât (10) relié par une articulation flexible (9) à la coque (1). Ce mât porte une grand-voile (29) et un foc (34). Ces voiles sont tendues par un gréement au mât et aux deux bômes (21 et 22). Un gréement supplémentaire comporte des drailles avant et arrière (37, 38 et 15, 16) et des haubans (18) entre la tête de mât et les bômes. Une barre d'écartement (25) sépare les bômes de façon rigide. Cette barre d'écartement peut pivoter autour du màt mais peut être partiellement fixée sur lui par une corde de rappel. Des coulisses en nylon (13) sont adjointes à la grand-voile et glissent dans des gorges pratiquées dans le mât, alors que le foc est attaché aux drailles avant par des anneaux (36).
