Abstract: The invention is a water diverter apparatus comprising—a housing (10) having an inlet section (12) and two outlet sections (14), with a separation angle of less than 180° between the outlet sections (14), and—a flow directing member that can be adjusted by rotation about a shaft (18) supported in the housing (10). The apparatus is characterised in that—the flow directing member is a closing member (16) arranged downstream of the shaft (18), the closing member (16) being connected with the shaft (18) via a spacer (17) and having a closing surface arranged transversely to a flow direction, the closing member (16) having a first position adapted to close one of the outlet sections (14), a second position adapted to close the other outlet section (14), and a third position between the first and the second positions, adapted to allow water to flow into both outlet sections (14). The invention is furthermore a method for operating a water diverter apparatus.

Abstract: A recreational water sled that is designed to be towed by a speed boat or a jet ski. The water sled has an elongated boat body having a superstructure extending upwardly from its top surface. The superstructure has a rider seat portion and a nose portion having a dashboard located on its tear end. The top end of a steering column extends from the dashboard and it has a handle bar secured thereto. The bottom end of the steering column is secured to a rudder in the form of a ski or disk-shaped rudder. The front end of the boat body receives a tubular quick release housing that is structurally secured therein. A front end of a tongue assembly is releasably captured in the tubular quick release housing. The tongue assembly has a floating tow rope attachment assembly secured to its rear end. A hand actuated lever on the handle bar releases the tongue assembly from the boat body.

Abstract: The invention features a device for generating a plume of water, the device including a) a first side wall, b) a second side wall extending at an angle to the first side wall, the first side wall and the second side wall defining a tapered channel, the channel including i) a first end, ii) a second end, and iii) a longitudinal extent extending between the first end and the second end, c) a first flange extending at an angle to the first side wall, and d) a second flange extending at an angle to the second side wall.

Abstract: Steerable towcraft having a buoyant body upon which a person can ride, a towline attached to body and adapted for connection to the pulling vessel, a fin on the under side of the body for guiding the body through water, and a steering line connected to the towline at a point spaced from the body. By pulling on the steering line, a person riding on the body can change the angle of the fin relative to the towline, and thereby control the direction in which the towcraft is moving. Water is taken in from beneath the body and sprayed in the form of a roostertail into the air behind the craft as it travels through the water. In some embodiments, a whistle or other noisemaker is actuated by the water forming the roostertail.

Abstract: A water diverting apparatus for adaptation to a recreational motor ski vehicle. The apparatus provides a water rooster tail during the operation of the motor ski vehicle without degrading the nominal speed of the motor ski vehicle or preventing agile maneuvering of the motor ski vehicle.

Abstract: A long and slender box shaped fin holder, that provides a pinned connection between the fin and the holder box. The pinned connection is located within the box itself, so as to allow rotational capabilities, while also offering lateral stability to the fin from the sides of the holder box. The rotational freedom of the fin is regulated by a spring type device attached to the leading edge of the fin and at the same time, to the forward wall of the holder box. The holder box is also equipped with a latch type device to facilitate locking the fin in a fully retracted position, which primarily conceals the fin within the holder box. This holder box is embedded within the top and the bottom surfaces of a typical surfboard, kneeboard, or windboard, typically near the rear of the board.

Abstract: Several embodiments of signalling devices for small jet propelled watercraft that generate an upwardly discharged water spray for indicating the presence of the watercraft. In each embodiment, devices are incorporated for precluding the discharge of the signal spray if desired. In some embodiments, this is done by a control valve while in other embodiments this is done by redirecting the discharge portion of the signal generating device. In all embodiments, however, the signalling device is permanently fixed within the discharge nozzle of the jet propulsion unit.

Abstract: An attachment for mounting on the rear edge of a snow ski includes a mounting portion for securing the attachment to the ski, an extension portion extending rearwardly and downwardly from the mounting portion, a carrier portion extending rearwardly and upwardly from the exterior portion, and a blade element depending downwardly from the carrier portion. During use, the blade element penetrates a snowy surface to create a snow jet or "rooster tail" effect.

Abstract: This invention is a nozzle system for use on a water craft and in particular a water craft such as a jet ski. A jet ski is a small engine powered surface water craft, usually designed for one person usage, and generally having a small aft deck suitable for standing on by the user. Heretofore, nozzles used on jet skis were pivotally mounted and were used solely to propel or to propel and steer the craft in the water. This invention is for a modified nozzle that additionally produces a small but substantial secondary jet of water directed upwards that breaks through the surface of the water behind the craft and produces a "rooster tail" effect which adds to the safety, excitement and pleasure of the user and produces a spectacular water display that is enjoyed by those observing the craft and its user in action.

Abstract: A loading mechanism for loading water into a water storage tank of a water bomber aircraft is improved by separating the probe from the receiver conduit and by forming the probe with a cross-sectional area which is substantially less than the cross-sectional area of the receiver conduit. As a result of these improvements, the jet of water is discharged freely from the probe into the receiver conduit, thereby preventing the drag forces which are applied to the water passing through the receiver conduit being transmitted to the probe. A further improvement is in that the probe is positioned so that the input end is only partially exposed below the step with the result that an airspace is formed in the stream of water passing through the probe in use.
