Definitions

  • the present invention relates, generally, to the field of sail and mast assemblies for sailing vessels. More specifically, the invention relates to a sail and mast assem­bly of the type commonly found on sailboards and small sail boats, in which the sail area is easily adjustable to suit various wind conditions and sailing skills.
  • a sailboard comprises a bouyant elongated platform or board having a tapered "bow", on which a mast carrying a sail is mounted.
  • the mast is mounted to the board by means of a universal joint, allowing the mast to be turned and twisted, by means of a laterally-extending boom, to adjust the attitude of the sail with respect to the wind, thereby controlling the speed and course of the board.
  • the sail on sailboards usually has a fixed, non-­adjustable area.
  • the area of the typical sailboard sail i.e. approximately 60 to 64 square feet
  • a larger sail suitable for light wind con­ditions a "light air” sail
  • a smaller one adapted for heavier wind conditions a "heavy air” sail.
  • the typical sail is an attempt to optimize performance in average wind conditions, and is, therefore, not suited for optimal performance in light or heavy wind conditions.
  • the present invention is a sail and mast assembly in which sail area is adjusted by means of at least one removable section or panel attached along the bottom edge, or "foot,” of the sail, and in which the height of the mast is adjustable as a sail panel is removed or added.
  • the sail comprises a main sail section, the foot of which includes fastening means which allows the removable attachment of a transverse section or panel.
  • the panel increases the length of the sail's luff and leech, thereby also increasing the overall area of the sail.
  • Two or more such panels can be used, if desired, in which case the panels will include attachment means on their upper and lower edges. (The attachment means can, of course, be omitted from the lower edge of the lowest panel.)
  • the mast is adjustable in height, as mentioned above, to accommodate changes in the length of sail luff, as panels are added or removed.
  • Mast height is adjustable by means of telescoping upper and lower mast sections or as one alternative, the mast can include one or more removable mast segments serially attached to the top or bottom of the mast, with each mast segment having a length approximately equal to the length of luff added by a corresponding sail panel.
  • the mast height can be adjusted, as sail panels are added or removed, to maintain the same proportion of mast height to sail luff.
  • the sail sections are joined along their adjacent edges by means of a zipper or a series of snap fasteners or the like.
  • the panels can be configured so that each panel can provide an additional amount of seam shape to the sail. In this manner, the fullness of the sail can be increased and decreased as panels are added and removed, respectively, thereby enhancing the sail's adjustability to varying wind conditions.
  • the sail area is easily and quickly adjusted to suit wind conditions varying from light air to heavy air.
  • the invention allows the same board to be used by both a novice and an experienced enthusiast without completely changing the entire sail.
  • the changes in sail area are accompanied by appropriate changes in mast height, hereby maintaining the proper relationship between mast height and sail luff, and avoiding the problem, mentioned above, of excess weight aloft in heavy air.
  • the draft of the sail can be maintained at its optimum position regardless of the sail area selected, since all sail area is added or removed from the foot, rather than the leech.
  • the sail system of the present invention includes a load strap arrangement which transfers force from one panel to another without placing appreciable pressure on the joined-­together sections of the sail.
  • the sail system of the present invention also includes segmented battens insertable in the separate remov­able sail panels.
  • the sail system of the present invention further includes a batten which is selectively insertable in the batten pockets of different sail panels.
  • a sail and mast assembly in accordance with the invention, which is economical to manufacture, easy to use, and readily adaptable for use with both sailboards and small sail boats, as well as other types of wind-driven craft.
  • a sailboard 10 is shown with a sail and mast assembly in accordance with the first preferred embodiment of the invention.
  • the sailboard in most respects is of typical design, having a platform or board 12 on which a person stands, a mast 14 mounted on the board 12 by means of a universal joint 16, and a fore-and-aft rigged sail 18 carried on the mast 14.
  • a boom 20 extends horizontally rearwardly from the mast 14, and is used to rotate the mast on the universal joint 16 to change the attitude of the sail 18 with respect to the wind, thereby to navigate.
  • the sail has a leading edge or "luff” 22 part of which forms a sleeve 24 into which is inserted the upper part of the mast. Below the sleeve 24, the luff 22 is attached to the mast by one or more straps 26.
  • the sail 18 has a bottom edge or "foot” 28 extending from the luff 22 to the sail's trailing edge or "leech” 30, which extends distally from the mast. At the juncture between the foot and the luff, or “tack”, is a tack patch 32, and at the juncture between the foot and leech, or "clew”, is a clew patch 34.
  • a downhaul line 36 is connected between the tack patch 32 and the universal joint 16, in a manner to be described below.
  • An outhaul line 38 connects the boom 20 to the clew patch 34. The outhaul line 38 thus connects the sail 18 to the boom 20 so that navigation can be accomplished, as mentioned above.
  • the sail area is adjustable by the addition and removal of sections or panels along the sail's foot, and that the height of the mast is adjustable in accordance with the changes in the legnth of the luff resulting from the addition and removal of the sail panels.
  • the sail 18 is divided into a main sail section 40 and two panels 42 and 44 removably attached to the bottom edge of the main section 40. More specifically, the first panel 42 is attachable along its upper edge to the bottom edge, or "foot", of the main section 40, while the second, or lowermost panel 44 is attachable along the upper edge to the lower edge, or foot", of the first panel 42.
  • Each of the panels 42 and 44 has a luff edge alignable with the luff edge of the main sail section 40. As best shown in Figure 4, the panels 42 and 44 are separately attachable and removable, so that the sail 18 can be rigged with both of the panels, or just one, or none (using the main section 40 alone).
  • the preferred means for removably attaching adjacent sail sections is a zipper 46, two of which are used in the illustrated embodi­ments.
  • the zipper 46 provide seams along which adjacent sail sections are joined together, with the two sides of each zipper 46 being sewn into either side of each of these seams.
  • fore and aft load straps 48a and 48b, respectively, are provided at the upper corners of each of the removable panels 42 and 44.
  • the load straps 48a and 48b pass through grommets 50 in the tack patch 32 and clew patch 34 of the adjacent sail section, looping around the zipper 46 between the two sections, and are fastened by means such snap fasteners 52 or the like.
  • the zippers 46 extend forward beyond the luff, as shown in Figure 2, so that they can be wrapped around the mast and tucked under the forward load straps 48a, as shown in Figure 3.
  • the free end of the zipper can then be fastened to the side of the sails section by a suitable fastener 54, which may be a snap or a VELCRO fastener.
  • zippers are shown as the preferred means of attaching adjacent sail sections, other means can be used.
  • snap fasteners or self-adhesive strips such as VELCRO may be used as alternatives.
  • the mast has a "telescoping" structure to allow adjustment of its height.
  • the mast comprises a lower tubular section 56 attached to the universal joint 16, and an upper tubular section 58 which slidably fits into the open upper end of the lower section 56.
  • the upper section 58 is provided with a plurality of holes 60 which are each registerable with a hole (not shown) near the top of the lower mast section 56.
  • a pin 64 is insertable into the registered holes to fix the mast at the desired height.
  • the number of holes 60 may advantageously correspond to the number of sail sections, with the spacing between the holes 60 corresponding, at least approximately, to the length of luff or each of the removable sail sections.
  • the downhaul line 36 is connected between the tack patch 32 and the universal joint 16. This connection provides the proper downward tensioning of the sail 18, and is accomplished (as shown in Figure 5), by pair of hooks 66 insertable into a tack patch grommet 68 and an eyelet 70 on the universal joint 16.
  • the lower-­most sail panel 44 can be removed, by means of the zipper 46, and the mast correspondingly shortened by telescoping the upper mast section 58 into the lower mast section 56 until the middle one of the holes 60 is in registration with the hole in the lower mast section, with the pin 64 then being inserted therethrough.
  • the outhaul and downhaul lines are connected to the clew and tack patches, respectively, of the middle sail panel 42.
  • both panels 42 and 44 will be unzipped from the main sail section 40, and the mast 14 will be shortened to its minimum height by sliding the upper mast section 58 into the lower mast section 56 until the uppermost of the holes 60 registers with the hole in the lower mast section and then inserting the pin 64, as described above.
  • the outhaul line and the downhaul line will then be attached to the clew patch and tack patch, respectively, of the main sail section.
  • sail area can be in­creased by re-attaching the panel 42 alone, or both of the panels 42 and 44, while correspondingly increasing the mast height.
  • the preferred embodiment described above provided optimum sail and mast con­figuration over a wide range of wind conditions, with ease of adjustability of the sail and mast configuration to accom­modate changes in wind conditions. There is no compromise in the handling qualities of the sailboard as a result of the adjustability of the sail and mast.
  • FIGS. 7 through 14 there is shown another form of sail and mast assembly embodying the present invention mounted on a sailboard 10′.
  • the mast generally designated 14′, supports a boom 20′.
  • the mast 14′ includes a main section 80 which telescopically removably supports an upper section 82.
  • Upper section 82 includes a stub 83 which is snugly received within a socket 84 formed in the upper end of main mast section 80.

  • the mast and boom carry a sail 18′ which is divided into a main sail sectin 88 and two panels 90 and 92 removably attach to the bottom edge of the main section 88 by zippers 94 and 96.
  • a plurality of battens 98, 99, 100 are provided for the main sail section 88.
  • a downhaul line 103 secures the lower front portion of sail 18 and its attached panels 90 and 92 to a conventional anchoring member 104 securing to the rear of the mast 14′ below the lower panel 92.
  • the front end of main sail panel 88 is formed with a sleeve 105 for telescopic engagement with mast 14′.
  • the sleeve 105 is open at area 106 to permit the front end of boom 20′ to be attached to the mast in a conventional manner.
  • the lower front portion of the main sail section 88 is provided with a grommet 108.
  • the lower front portion of sail panel 90 is provided with a similar grommet 110, while the lower front portion of the lower sail panel 92 is also provided with a similar grommet 112.
  • a first vertical load strap 114 is secured to the upper removable sail panel 90 and is connected at its upper end to a snap hook 116 shown particularly in FIG. 7.
  • the snap hook 114 is removably insertable within grommet 108 of the main sail panel 98.
  • a similar load strap 118 is secured at its lower end adjacent the front edge of lower removable sail panel 92.
  • Such load strap is provided with a hook 120 similar to the hook 116.
  • Hook 120 is removably engageable with grommet 110 of the upper removable sail panel 90.
  • the pressures applied to the removable panels 90 and 92 are not transmitted through zippers 94 and 96 to thereby prevent damage thereto.
  • the hooks 116 and 120 are readily attachable to and detachable from their respective grommets.
  • horizontal straps 124 and 126 extend from grommets 110 and 112, respectively, to encircle the mast 14 so as to removably attach the lower front portions of the removable sail panels to the mast.
  • batten member 102 consists of an upper section 130 disposed within batten pocket 132 formed in the lower front portion of main sail section 88, an inter­mediate section 134 carried in a batten pocket 136 formed in the intermediate portion of upper removable sail panel 20 and a lower section 138 removably carried in a lower batten pocket 140 formed in the intermediate portion of lower removable sail panel 92.
  • the adjoining batten sections are telescopically jointed by like pin and socket connections 44.
  • the rear end of batten 138 is remov­ably secured within its batten socket 140 by a retainer loop 150 having its front portion secured to the rear edge of removable lower panel 92 in a conventional manner.
  • FIG. 13 there is shown another form of sail and mast assembly embodying the present inven­tion.
  • a single batten 160 is selectively insertable within a lower batten pocket 162 formed in a lower removable sail panel 92, an intermediate batten pocket 164 formed in upper removable sail panel 90 or an upper batten pocket 166 formed in the lower portion of main sail section 88.
