Sports equipment comprising a ski (1) and a lift group (G); the ski (1) comprises a longitudinal axis (Z), a tip (11), a tail (12), two lateral edges (13) and a bridge-like structure (15), arranged between the tail (12) and the tip (11), above the ski (1); the bridge-like structure (15) comprises a hooking surface (15a) for bindings (AT) of a user's boot and defining, on a lower side, a duct (16); said lift group (G) comprising an engine unit (M) comprising a motor (2) and a drum (4) moved by the motor (2), a management and control unit (U) connected to the motor (2), a first roller (51) arranged on the tip (11) of the ski (1), a second roller (52) arranged on the tail (12) of the ski (1) and a belt (6) closed on itself and wound longitudinally around the ski under a condition for which it slides around the two rollers (51, 52), being dragged in rotation by the above-mentioned drum (4) and being slidingly inserted on the duct (16); the belt (6) is equipped with a rib sliding in a groove of the ski (1).

The invention relates to a winch system intended, in particular, for water sports, comprising at least one frame, at least one motor, a brake system, and a main tension cable wound around two spools, each spool being actuated by a motor such that when one of the spools unwinds the main cable, the other spool winds up the cable such as to maintain both the unwinding speed and the tension required for the main cable.

A portable hoisting device configured to be connected to a cable secured to a destination location for hoisting at least one person from a start location to the destination location is provided. The device includes a winch mechanism having a drum body shaped and adapted to have the cable wrap around the drum body. The winch mechanism is operable to selectively wrap the cable around the drum body. The device has a gear train operatively connected to the drum body and operable to engage the drum body in rotation, a motor operatively connected to the gear train, a control assembly operatively connected to the motor to control same, and a latching assembly adapted to enable a load to be connected to a component of the portable hoisting device, wherein the control assembly comprises a remote control configured to send signals to the motor remotely.

The disclosure provides a reversibly interlocking device for attaching one or more objects to a strap, which includes a first carabiner including a first base portion with a first strap attachment, a first proximal end including at least one lip, and a first distal end including two or more tabs; and a second carabiner including a second base portion with a second strap attachment, a second proximal end, and a second distal end, wherein the first carabiner reversibly interlocks with the second carabiner through the at least one lip and the second distal end, and through the two or more tabs and the second proximal end.

An underwater propulsion system is disclosed comprising a foot board with one or more battery-powered propulsion units. A throttle control system may be enabled in the foot board such that a movement of the user's foot controls the throttle. Flattened Lithium batteries allow thin lightweight construction of the foot board. Use of trolling motors as propulsion units provides thrust advantages over pre-existing underwater scooters.
