A training harness system for snow sport training includes: a training harness that is wearable by a student, including: a harness body with a central leash receiving structure and left and right leash connector assemblies, each including at least one leash receiving structure with an elongated aperture; and a leash assembly, including first and second leashes, each including: an elongated leash member; a leash handle; and a leash connector with a hook portion, that includes an elongated hook member, such that the elongated hook member detachably connects with the at least one leash receiving structure; such that the training harness system enables a trainer to control and guide skiing or snowboarding of a student. The training harness system is configurable for beginner, intermediate, and advanced students, with different connections of the right and left leashes to the training harness.

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.

A power-assisted ski track setter including a user control assembly, a track cutter assembly, and a drive assembly configured to operably engage the track cutter assembly is provided. The user control assembly is configured to control the direction of the power-assisted ski track setter. The track cutter assembly comprises a frame, a set of wheels operably coupled to the frame, a set of axles operably coupled to the wheels, and a set of tracks encircling the set of wheels. The set of wheels rotatably supports the frame. The drive assembly is configured to be mounted adjacent to the frame. The drive assembly comprises a motor configured to transmit power to the track cutter assembly, a battery electrically connected to the motor, and a drive gear operably coupled to the motor.
