Abstract: A personal water craft (PWC) dock has a molded platform, the platform having a main section with its upper surface contoured to provide an elongate recess extending the length of the platform. The recess is shaped and dimensioned to receive and support the hull of a PWC, the recess being asymmetrically located towards one side of the platform. A raised walkway deck section extends the length of the platform and is located towards the other side of the platform, the walkway deck section being located over a buoyancy chamber. The molded platform is configured at each end of the recess for selective installation of a centering roller or a bow stop as desired for convenience when siting the PWC dock and its walkway deck section in relation to a main dock.

Abstract: A winch for moving a load along a track from a first position to a higher position has a drum around which a retrieve and a launch cable are wound in different directions. Rotation of the drum acts to reel in one of the cables while paying out the other. The retrieve cable extends directly between the drum and the near end of the load and the launch cable extends past the rear of the load though a sheave mounted on the track, and then back to far end of the load. A winding mechanism operates in retrieve mode to turn the drum to reel in the retrieve cable and pay out the launch cable. The winding mechanism is used in launch mode to turn the drum in the opposite direction to pay out the retrieve cable and reel in the launch cable. A brake mechanism is operable to halt runaway of the load along and down the track when the winch is being operated in launch mode.

Abstract: A carriage-on-base system for use in winched movement of a load, the carriage shaped to support a load to be winched along the base, the carriage having a plurality of depending housings, a plurality of slider of ultra-high molecular weight polyethylene (UHMWPE) fixed in respective housings, the base having rails engaged by the sliders with lower surface profiles of the sliders matched to upper surface profile of the rails which they engage, the profiles of the rails and the sliders at their interengagement preventing any movement of the carriage relative to the rails other than sliding movement of the carriage along the rails.

Abstract: A bunk cushion assembly for supporting a boat comprises a bunk having an elongate base and an elongate cushion mounted to the base and extending along its length. The elongate cushion is formed from an extrusion of a first resilient material and another extrusion of a second resilient material. The second extrusion forms an insert contained within a cavity in the first extrusion. The outer extrusion material is harder and less elastic than the inner extrusion material.

Abstract: A boat lift apparatus includes a base having a first base beam and a second base beam and a moveable boat support platform having a first lifting beam, a second lifting beam, and at least one cradle support connected to and suspended between the first and second lifting beams. At least two first support struts connect the first base beam and the first lifting beam, and at least two second support struts connect the second base beam and the second lifting beam. When the boat support platform is in a lowered position the at least two first support struts are generally parallel to both the first base beam and the first lifting beam, and the at least two second support struts are generally parallel to both the second base beam and the second lifting beam.
