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.

Described herein are watercraft comprising a hull comprising a first hull assembly, and a second hull assembly opposite the first hull assembly and parallel to the first hull assembly; and a frame configured to couple the first hull assembly to the second hull assembly. In sonic embodiments, the first hull assembly comprises a first quarter hull coupled to a second quarter hull, and the second hull assembly comprises a third quarter hull coupled to a fourth quarter hull. In some embodiments, the first and third quarter hulls are substantially reflectively duplicative of the second and fourth quarter hulls. In some embodiments, the first hull assembly is substantially reflectively symmetrical to the second hull assembly. Various embodiments may further include a roof comprising one or more energy harvesting arrays thereon. The roof may be movable, in various embodiments, between a closed configuration and an open configuration.

A posture control system for a hull, and a marine vessel including the posture control system, allows crew members to fish more comfortably and includes a posture control tab attached to a stern of the hull to control a posture of the hull, a driver to drive the posture control tab, and a controller to control the driver. When it is determined that the hull has changed to a fishing mode, the controller causes the driver to raise the posture control tab to a predetermined position.

Disclosed are embodiments of a table assembly for a boat docked near a landing. The table assembly consists of three essential components: (1) a table having an upper surface and an underside surface; and (2) a leveling mechanism secured to the underside surface. In one embodiment, a third essential component is: (3A) a pair of hooks secured to the leveling mechanism. In another embodiment, a third essential component is: (3B) a pair of claws secured to the table underside surface.

A canopy extension system is cooperable with a support structure and includes a canopy arm securable pivotably to the support structure and a roller arm securable pivotably to the support structure. A roller is secured on the roller arm. A canopy is connected to the canopy arm at a distal end, is connected adjacent the support structure at a proximal end, and is connected to the roller between the distal end and the proximal end. A variation connects the canopy arm to a radar arch or the like with a spring-biased secondary canopy arm.

An exhaust system on a boat can be dangerous if the exhaust is not plumed properly through the boat. If a boat has a tower on it the exhaust can be plumed through it. The tower will be made to accept the exhaust gasses. The tower will still look the same except there will be tips sticking up on each side of the tower where the exhaust will escape.
