Abstract: A trailer for transporting a contemporary boat hoist having a four post rectangular structure with at least a front transversely extended front beam and a pair of side beams, the trailer including a frame having side members mounted on a wheel and axle unit, with a pair of arms pivotally mounted one on each side member of the frame and connected to the unit, with further a front mounted winch cable connected to the arms whereby operation of the winch results in a raising or lowering of the frame, with a second front mounted winch engageable with a front beam to raise the hoist; and an extension support unit mounted on the rear of the trailer and engageable with the hoist side beams to effect vertical movement of the hoist upon vertical movement of the trailer frame.

Abstract: A load guide system for guiding a craft into a apparatus such as a boat trailer, boat hoist or the like for egress from traveling on the water, the apparatus including a pair of stationary members of a framework spaced from each other and forming thereby an opening through which the craft is driven, the load guide system include a unit pivotally mounted on each stationary member, each unit including an upright pole engageable by the craft as it moves into the opening, and a spring biased pulley and cable assembly interconnected among the spaced members and the framework for biasing the poles toward each other, the normal condition of the poles forming an opening less than the framework opening, whereby upon one pole being engaged by the bow of the craft, should the craft not being centered upon entering the opening, the unit of that pole will act in response to operation of the pulley and cable assembly to force the bow toward the opposite pole, with the unit of the opposite pole reacting similarly, the seque

Abstract: Apparatus is disclosed herein for adjusting the length of a frame to fit a canopy tied onto and stretched over the frame. Each end of the frame includes a mounting bracket which is slid into an open end of a side tube with a friction fit. A sleeve is secured over the side tube with a flange engaging the outer end of the bracket. An adjusting nut and bolt engages both the flange and the bracket such that rotation of the nut against the flange causes the bracket to be moved axially within and of the side tube thereby lengthening the overall length of the frame relative to the canopy.

Abstract: A portable modular boat dock system of improved assembly and disassembly, which comprises a plurality of dock sections, a leg supporting unit for pivotal, detachable connection to a shoreward end of each dock section, a releasable latching unit for connection of adjacent dock sections to prevent both vertical and lateral relative movement, a lever-releasable unit for extending a telescoping foot for each leg for lake bed height adjustment, and improved accessory mounting structure. This system provides for simple installation of the dock without use of wheels, floats or standard tools.

Abstract: A torsion axle for a trailer for transporting a load such as a pontoon boat. The torsion axle assembly is part of a wheel unit for maintaining stability for the trailer during transport. The torsion axle is assembled to have two pairs of resilient elements and an elongated shaft housed between inner and outer elongated sections. The inner and outer elongated sections are held together temporarily by a weld and then releasably held together by releasable fasteners in a normal use position.

Abstract: The female unit is movably connected at its upper end to the implement upper end by a link device providing both vertical and horizontal pivotal adjustability therebetween, while their lower ends are pivotally connected.

Abstract: A seat locker assembly having an integrally formed base unit with a vented storage locker formed therein which is open at the top, an integrally formed unit including a seat, backrest and armrests pivotally connected to the front of the base unit for opening and closing thereover, and with fluid drain openings formed at the juncture of the seat and backrest for draining fluid from the seat downwardly for discharge at the rear of the backrest and over a rear lip of the base unit.

Abstract: A device for releasably holding down the skis of a snowmobile onto the floor of a flatbed trailer comprising a U-shaped channel, with a plurality of longitudinally spaced openings formed therein for adjustably receiving longitudinally spaced members, a handle pivotally connected to the channel for drawing tight in an over-center manner a strap entrained over and under the members, and an elongated tube placeable over the channel and under the strap, the tube ends of which engage and hold skis upon pivotal rotation of the handle in one direction effecting a tightening of the strap over the tube, opposite rotation of the handle loosening the strap such that the tube can be removed from over the skis.

Abstract: A boat trailer having a wheel and axle supported frame including a pair of parallel, longitudinally extended frame portions interconnected at their rear ends, and with a longitudinally spaced pair of V-shaped bracket units mounted on each frame portion, each pair of bracket units supporting a pair of elongated, laterally spaced, parallel pair of bunks, each pair of bunks for supporting a single personal watercraft, and with an arcuate element secured to and extended forwardly from each frame portion and supporting at a forward end a winch unit.

Abstract: A boat trailer having a wheel and axle supported frame including a pair of V-shaped cross members supporting a pair of elongated, laterally spaced bunks for supporting a single personal watercraft, a tongue unit longitudinally adjustably attached to the front of the frame, and a winch mounting assembly including a winch post longitudinally adjustably mounted on the tongue in a plurality of vertically adjustable positions for carrying a bow stop and a ratchet-action winch mounted intermediate the ends of the post for strap engagement with the watercraft.

Abstract: In a boat hoist having a platform for raising and lowering a boat by a normally manually rotated circular lift wheel, winch, and cable arrangement, an electrically powered drive motor assembly mounted adjacent the lift wheel and including a drive wheel biased between a position of non-engagement with the lift wheel, and a position of engagement therewith for rotation of the lift wheel, power for the drive motor provided by the DC power source within the boat being moved or by a shore supplied AC power source.
