Implementations of improved watercraft comprising a hull with a portion of the bottom face of the hull having a greater displacement from the top face of the hull at a first forward position and a second portion of the bottom face of the hull having a lesser displacement from the top face of the hull at a second rearward position, such that the forward portion of the bottom face does not lift out of the water when a load is placed toward the rear of the watercraft. The watercraft may incorporate additional desirable features such as non-slip standing surfaces, drainage structures, equipment storage, and stability increasing structures.

Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

The invention relates to a watercraft comprising an at least partly elastic and preferably inflatable casing (1), in particular a casing which surrounds an inner region. The watercraft has a base (2), an energy storage device (6), and a drive device which is secured to the base and comprises a drive unit (4) that is located in the water during operation, the flow of water produced by the drive unit during operation being controllable by means of a controller. The drive device is releasably secured to the base as a module comprising the energy storage device (6), which is designed as part of the module, such that the module can be removed as a structural unit.

An articulating top having a frame, a cover attached to the frame and a mounting bracket to attach the frame to a vehicle can be moved between a deployed position to provide shelter to an area below the top and a stowed position. The frame having main and secondary frame members in addition to one or more struts between a frame member and the vehicle to provide additional support to the frame such that the top can be used while the vehicle is in motion or in windy conditions. The top may also use one or more braces.

A watercraft with improved safety and stability is provided. The watercraft includes a shell defining a plurality of raceways for receiving water during certain maneuvers of the watercraft, thereby exerting force upon the watercraft in a first direction. The shell is configured so as to prevent or otherwise inhibit the water from exerting an opposed second force upon the watercraft. An intermediate panel of the shell provides increased flexibility, thereby serving as a shock absorber for the watercraft.

The specification discloses a watercraft drain plug system that includes two or more drain plugs, an actuator, and a cable assembly interconnecting the drain plugs and the actuator. The actuator may be operated to move the drain plugs between open and closed positions. The actuator includes a locking mechanism for securing the actuator in the closed position to prevent inadvertent opening of the drain plugs.

A stabilized flotation platform that is used for supporting supplies for those enjoying time in the water. The uniqueness is the stability provided by its construction such that materials contained on or in the device do not spill into the water.
