Definitions

  • the watercraft comprises at least one planing ski having an upright stand secured thereto and a seat and transverse steering bar attached to the stand.
  • FIG. 1 is a perspective view of a watercraft-embodying this invention.
  • FIG. 2 is a side elevation view of the watercraft.
  • the illustrated watercraft comprises a horizontally disposed planing ski 1 removably attached to an upright stand.
  • the upright stand 2 is comprised of a pair of spaced vertical support members disposed on said ski with the forward member having a horizontal and forwardly extending section extending from its upper end and terminating in an upward section.
  • a seat 3 is connected to and supported on said members 2 vertically above the ski and a transverse steering bar 4 removably attached to the upward section.
  • the steering bar terminates at its outer ends at two hanEiIFgiip'sE 8 by manual control means, such as a cable controlled hand lever 10, mounted adjace'rif'foilia n dle stfie latch rhiiib'i'dtild comprise a hooked end, for example, which would automatically release member 8 under the force of the spring upon release of lever 10.
  • manual control means such as a cable controlled hand lever 10
  • mounted adjace'rif'foilia n dle stfie latch rhiiib'i'dtild comprise a hooked end, for example, which would automatically release member 8 under the force of the spring upon release of lever 10.
  • Seat 3 and float 7 preferably comprise a floatable material having a specific gravity substantially less than I 1.0 to normally prevent the ski from sinking below water level by providing a composite specific gravity for the watercraft which is less than l.0.
  • Such floating means will thus maintain the craft upright to facilitate embarking and debarking in deep water even though the stand and ski may have specific gravities greater than 1.0.
  • the rider when the craft is started in shallow water or from a beach, the rider has the advantage ofa relatively low center of gravity due to the construction and arrangement of the frame and attendant constructions.
  • the position of seat 3, float 7 and handle grips 5 in relation to ski 1 may be adjusted by means, not fully shown, to accommodate riders of various sizes.
  • the rider is normally seated on seat 3 to have his knees placed on opposite sides of float 7, his feet on ski 1 and his hands on handle grips 5 and 5.
  • a comfortable posture is realized in that the riders upper arms and lower legs are disposed essentially parallel to the trunk of his body and his lower arms and thighs are main tained roughly perpendicular thereto.
  • the width of the ski's rearward or trailing end is preferably constructed to be narrower (e.g., two-fifths) than its forward end.
  • the ski is preferably tapered rearwardly and is rounded at its forward end.
  • the vertical height of quick release means 8 for the tow line should essentially equal the vertical height of the seat.
  • the quick release means should be positioned at a longitudinal distance from the seat which is preferably not less than one-third of the overall length of the ski.
  • the front half of the ski preferably points upwardly relative to the rear half thereof (FIG. 1) to form an obtuse planing surface angle so that planed water will be thrown aside to prevent impairment of the riders vision.
  • the single ski could be replaced by two or more parallel skis laterally spaced at a suitable distance and connected together by a plate covering the space therebetween.
  • the plate could be made adjustable in a lateral direction to selectively change the distance between the two skis.
  • Such a modification would facilitate starting, reduce water splash during travel and provide additional space for the rider's feet, especially when the rider wears miniature skis or webbed flippers for stunt-riding.
  • the ski, seat, steering bar and float may be made detachable from each other by the use of standard couplings to permit-the watercraft to be disassembled for transport purposes.
  • a planing watercraft adapted to be towed comprising a single substantially horizontally disposed planing ski, an upright stand rigidly connected to said ski and comprised of two vertical spaced supports with said forward support having a forward horizontal portion at its upper end terminating in an upward section, a seat mounted on said supports extending lengthwise m the direction of said ski, vertically above and intermediate the ends thereof, a transverse steering bar mounted c n 3 1Aspit s29-ssfi iffi iii i ir l lfis i Said 5k?

  • am ""e watercraft or claim '3 whereihsaid uicifi lease means is at least approximately positioned at the same vertical height as said seat and at a distance from said seat which is not less than one-third of the length of said ski.
  • the watercraft of-claim 3 further comprising manually actuated control means attached to said steering bar and operatively connected to said quick release means for selectively releasing a tow line from said watercraft.
