A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.

The present invention provides lightweight fluid-jet thrust pack which provides three rotational axes and reduced restriction of fluid flow to the output nozzles. A first rotational axis is provided by a first rotatable coupling that is concentric with a coupler for a hose supplying pressurized fluid. The top of the first coupling has a splitter which directs incoming fluid into two splayed stub supply pipes. A preformed, reinforced rubber hose connects each stub supply pipe to one of a pair of coaxial rotatable couplings at opposite ends of a tiltable cross arm assembly that is pivotally secured to tower support bracket that is secured to the first rotatable coupling. An outward rotatable portion of each of the coaxial rotatable couplings is equipped with one boot-mounting platform and a downward-projecting jet nozzle that is in communication with the stub receiver pipe of the same rotatable coupling.

The invention relates to a fluid outlet interface for a personal watercraft, so that the latter can collect and divert a very small portion of the fluid pressurized by said vehicle and thus create a sufficient Venturi effect to drive the emptying of the bilge of said vehicle. The invention also relates to a personal watercraft, or more generally any floating device delivering a pressurized fluid, comprising such an interface.

The oxygen tank flotation device is a floating structure adapted for use in recreational water activities. The oxygen tank flotation device is adapted for use with respiratory equipment that is required for use during recreational water activities. The oxygen tank flotation device receives and stores respiratory equipment, such as an oxygen tank, in such a manner that the respiratory equipment will float when the oxygen tank flotation device is placed in a body of water. This arrangement allows the respiratory equipment to float near the user when the user is involved in recreational water activities. The oxygen tank flotation device comprises a vessel, a first float, and a second float.

The present invention relates to an improved vehicle for use in water, in particular into the sea. More specifically, the invention relates to the structure of a vehicle of type called configured to have a hydrodynamic profile and to allow a user to turn with greater speed.

An arrangement (100) for underwater activities includes a reservoir (101), which reservoir includes a wall (102) securing a space inside the reservoir (101) to be filled at least partially with water (103). The arrangement has also an opening (104a, 104b) for entering the reservoir, and a container (105) to be filled at least partially with water (103). The container receives the reservoir (101) so that the lower portion of the reservoir including at least one opening (104a) is located under the water surface level (103). The lower portion of the reservoir when introduced with the container is securing together with the container's (105) wall an upper portion (107) of the container, which upper portion (107) supports via the opening (104a) the pressure difference between the upper portion (107) of the container (105) and the space inside the reservoir (101), when water (103) is introduced into the space inside the reservoir.

A supplemental bumper apparatus for covering the bumper of a personal water craft and providing enhanced shock absorption and blemish resistance. The supplemental bumper apparatus comprises a synthetic rubber body and a fastener system. The synthetic rubber body provides a barrier which can absorb shock and block blemishes from an impact. The synthetic rubber body is attached to the bumper fastener system defined by a plurality of snap fasteners on its upper section and a hook and loop fabric fastener is on its lower section. A plurality of snap fastener base members are permanently attached to the bumper and a corresponding hook and loop fastener material is permanently attached to the bumper, each providing a corresponding engaging member to enable the snap fasteners and the hook and loop fastener surface to attach the synthetic rubber body to the surface of the bumper.

A jet propelled watercraft includes a reverse gate that moves to a first position and to a second position. When the reverse gate is in the first position, the reverse gate causes a vessel body to move forward. When the reverse gate is in the second position, the reverse gate causes the vessel body to decelerate or move backward. A velocity mode selector is used to select a normal mode or a velocity mode. The velocity mode has a maximum velocity different from that of the normal mode. When the reverse gate is in the second position and the velocity mode is selected, a controller is configured or programmed to set an upper limit of an engine rotation speed in the velocity mode to be different from that of the engine rotation speed in the normal mode.

Disclosed herein is a personal watercraft that includes a hull including a deflectable panel having an interior surface and an exterior surface, an audio source for generating an audio signal, and an audio tactile transducer mounted to the interior surface of the deflectable panel. The audio tactile transducer includes a transducer enclosure, an audio generating device within the transducer enclosure, and an audio input for transmitting the audio signal from the audio source to the audio generating device. The audio generating device is configured to vibrate the deflectable panel based upon the audio signal in order to generate audible sound emanating from the exterior surface of the deflectable panel. The personal watercraft also includes a protective outer shell surrounding the transducer enclosure.

A floating construction comprising a container filled fully or partially with water, the lower portion of the container being located within a surrounding body of water and the water surface level of the surrounding body of water being substantially lower than the water surface level inside the container, the container comprising transparent walls or walls with transparent sections and at least one open opening for entering the container, which at least one open opening is located below the surface level of the surrounding body of water, and which floating construction comprises space for spectators observing activities taking place inside the container, wherein the floating construction comprises at least one ballast tank, which ballast tank is connected to the container with a controllable pressure connection, and which ballast tank has controllable water connection to the surrounding body of water.
