Definitions

  • the present invention relates to an improved design of sail especially suitable for use with sailboards.
  • Sails currently used in both sailboarding and boating in general include a number of battens.
  • the battens may be long battens which traverse the full width of the sail or short battens which go part way into the sail.
  • This pressure may be applied by means such as webbing and buckle, webbing and velcro, mechanical devices or cords and eyelets.
  • the pressure can be applied from either the luff (front) edge of the sail or from the leech (aft) edge of the sail.
  • Short battens are used only to give support to a short width of sail cloth. The area of sail being supported by short battens is usually the leech of the sail although they are used in the foot of the sail also. Short battens are not placed under high pressure loads.
  • the present invention provides a sail system comprising a sail, being a sheet of fabric extending lengthwise of a mast and attached to the mast at a plurality of points along its length for rotational movement thereabout, said sail having luff and leech edges and incorporating a plurality of full length battens extending between the luff and leech edges and attached to the sail along their length; characterised in that the said sail system further includes a plurality of short battens extending inboard of the sail from the luff edge, towards the leech edge, the short battens being located between full length battens.
  • one short batten is placed between two full length battens.
  • fabric includes, but is not limited, to conventional sail fabrics, such as close woven polyester fabric, a fabric/polymer film laminate, a fabric/scrim laminate, or a polymeric film.
  • short battens refers to battens that extend from one edge of a sail part way towards an opposite edge, preferably less than halfway.
  • a preferred design of sail uses both of these developments, short battens extending inboard from the luff edge of the sail are placed between full length battens, thereby improving the stability of the sail without the penalty of extra full length battens, and some of the compression load is transmitted from the long battens to the short battens
  • Transferance of the compression load is achieved by the use of very low stretch means, such as straps, extending from the luff end of the long battens to the inboard end of the short battens. In this manner some pressure is taken off the full length battens and is applied to the short battens thus enabling a reduction in the number of full length battens required to achieve a given design shape and stability of a sail when in use.
  • very low stretch means such as straps
  • the sail of the present invention is especially suitable for use with sailboards in which application the short battens extend from the luff side of the sail and the low-stretch means extend from the luff end of the full length battens to the inboard end of the short battens.
  • the inboard ends of the short battens are positioned on the line of tension between the head and tack of the sail; the inboard ends of the short battens may conveniently be secured to a seam, which term includes non-stretch material secured to the sail, formed along the line of tension when such seam (or material) is present.
  • the low-stretch means may be any woven or non-­woven material having a low stretch and which is flexible. Such materials include woven polyester cloth laminated to a polyester film, woven KEVLAR (R.T.M.) fabric, woven carbon fibre fabric or thick polyester fabric.
  • the low stretch means may also be a cord, wire or any flexible material that allows the sail to be rolled up.
  • a sail generally indicated at 1, has a luff edge 2, a leech edge 3, a head 4 and a tack 5.
  • Full length battens 6, 7, 8, 9, and 10 formed from glass reinforced plastics material extend from the luff edge of the sail to the leech edge 3, and are carried in pockets sewn into the sail in the conventional manner.
  • a sail formed from a close woven polyester fabric, generally indicated at 20, has a luff edge 22, a leech edge 23, a head 24 and a tack 25.
  • Full length battens 26, 27, 28 and 29 extend from the luff edge 22 to the leech edge 23.
  • Short battens 30, 33 and 36 extend from the luff edge 22 of sail 20 inboard and are positioned between full length battens 26, 27; 27, 28; and 28, 29 respectively. Both the full length and short battens are carried in pockets sewn into the sail in the conventional manner.
  • Non-stretch straps 31 and 32 link the inboard end of batten 30 to the luff edge ends of full length battens 26 and 27, similarly non-­stretch straps 34 and 35 link the inboard end of batten 33 to the luff edge ends of full length battens 27 and 28 respectively and the inboard end of batten 36 is linked by non-stretch straps 37 and 38 extending from the inboard end of batten 36 to the luff edge end of battens 28 and 29.
  • Non-stretch straps 31; 32; 34, 35 and 37, 38 are sewn into the sail and are formed of a woven polyester cloth laminated to a polyester film.
  • Sail 20 includes portions 20 a and 20 b that are separated by a seam 40 which is positioned along a line representing the line of greatest tension when the sail is in use.
  • the inboard ends 30 a , 33 a and 36 a of battens 30, 33 and 36 are secured to seam 40.
