A vehicle for conveying a rider within a tubular track comprises a support portion for supporting the rider and a retaining body adapted to retain the support portion against an interior wall of the tubular track. The retaining body has a sliding surface for slidable engagement with the wall of the tubular track. The support portion and the retaining body have a vehicle axis of movement about which the vehicle may rotate within the tubular track. An apparatus for transporting a rider comprises a tubular track having an interior wall and at least one vehicle.

A marine vessel or watercraft may be provided with an aft extension that, in one configuration of the watercraft, alters the wake of the watercraft, for example by reducing the height of the wake, and which may include a sealable opening to provide crew or payload access into or out of the watercraft at a location (e.g., aft of the transom) that may be difficult for an observer to perceive. The aft extension may be positioned above the watercraft's waterline when the watercraft is in another configuration such that it does not contact with the water to reduce adverse impact on performance characteristics, such as drag, of the hull when the watercraft is in that configuration. The watercraft may transition between the two configuration by selectively varying the displacement of the watercraft or by articulating of the aft extension.

The present invention relates to two configurations of structure for a compact, pedal-propelled boat, a recumbent configuration and a conventional configuration, and to two possible propulsion systems, one with rigid transmission system and other with flexible transmission system. Both configurations are used with hulls arranged in parallel, catamaran configuration, preferably inflatable, allowing the volume and size of the assembly to be reduced so as to fit in a car trunk, making it easier to transport and store. In the recumbent configuration, the boat driver is in a sitting position, with his back supported by the seat, and actuates the pedals located in the front part of the structure while maneuvers the boat by means of handlebars located on the sides of the structure. In the conventional configuration, the boat driver is in the same position as the rider of a conventional bicycle, and the seat, pedals and handlebar are arranged in the same positions as in a bicycle. The invention seeks to provide simple solutions and the greatest quantity possible of shared components between these configurations, such that a production plant can produce these configurations through as few production processes as possible and sharing as many production processes as possible.

A collapsible boat hull (10) with at least one bottom panel (16,18) and two side panels (12,14), and a removable transom (32) with attachment means (36) to engage the transom with the two sides of the boat hull, such that, during installation of the transom member, the attachment means initially engages with the sides of the boat, and rotation of the transom to an upright position in the boat hull retains the attachment means and the respective sides of the boat hull together. Releasable latches (42,44) at the lower edge of the transom engage with retaining members (54) on the bottom panels. Seating or cross-bracing has (100) which releasably engage with retainers on the sides of the boat.

A multipurpose watercraft has a pair of catamaran pontoons supported by way of a transverse control bar at forward regions thereof. The watercraft may have an arched equipment rack framework extending above rearward regions of the pontoons. The watercraft also has a pair of electric motor thrusters located respectively beneath each pontoon and the control bar comprises a pair of controls operable by hand, each control operable to control a respective thruster forwards or backwards. Alternatively, the thrusters may be remotely controlled. This configuration allows an operator to be pulled behind the control bar horizontally between the pontoons, snorkellers to be pulled behind the watercraft for recreational sightseeing and/or for remote-control rescue operations.

Disclosed herein is a foldable canoe. More particularly, the foldable canoe is configured such that it is constructed by folding a single synthetic resin sheet along a folding line without using a separate structural frame, and after the use of the canoe, the synthetic resin sheet can be completely folded along the folding line to form a compact shape, thus reducing the volume and length of the canoe, thereby facilitating transportation and storage of the canoe.

A dinghy has a hull with gunwales supporting a Bimini top. The Bimini top includes a primary bow supporting secondary and intermediate bows. A UV stabilized polyester Bimini canvas is supported on the bows by fore, aft, and intermediate sleeve portions. The underside of the Bimini canvas supports port and starboard buoyancy aid assemblies each comprising a bladder which is inflatable by an inflation mechanism and CO.sub.2 cartridge, and is maintained in its collapsed state by tape loop assemblies adjustable by hook-pile self-fastenings which are frangible on inflation. A protective cover is stitched to the Bimini canvas and is provided with hook-pile fastening means frangible on inflation. A toggle handle pulls a lanyard which passes into the primary bow to operate the mechanism to inflate the bladder.
