An automatic swimming pool cleaner (APC) includes a body having a fluid outlet and a nozzle assembly for controlling an orientation of fluid flow exiting the fluid outlet. The nozzle assembly includes a nozzle with a plurality of blades that are rotatable relative to the outlet. The nozzle assembly may also include an actuator and a transmitter for automatically rotating the blades and for automatically controlling the orientation of the fluid flow exiting the fluid outlet.

Disclosed is an apparatus that floats at the surface of a body of water over that waves pass. Passing waves, and/or the motions they impart to the apparatus as they pass, result in a net and/or effective propulsion of the apparatus in at least a first direction relative to the geometry and/or structure of the apparatus, and typically, at least in part, toward a direction from that waves approach the apparatus.

A hydrofoil craft includes a deck, a hydrofoil disposed below the deck, a thruster that generates a thrust, and a thrust operator. The deck includes a chest placing portion on which a chest of a vessel operator is placed and a lower-limb placing portion that is disposed at a more rearward position than the chest placing portion and on which a lower limb of the vessel operator is placed, and the deck is arranged such that the vessel operator is able to ride on the deck in a prone position. The thrust operator is operated by the vessel operator to adjust the thrust of the thruster.
