The invention relates to a floating maritime vessel including at least one hull beneath a deck, the hull extending between a bow and a stern in a longitudinal direction of the vessel, the vessel including, on its lower part, a removable keel and, on its upper part, a conning tower erected above the deck, the keel being able to be descended below the hull and raised back through the hull, the keel including a lower end and an upper end, the upper end of the keel connecting to the hull when the keel is in its lowered position. According to the invention, the conning tower contains a keel-storage space and the keel and the keel-storage space of the conning tower are aligned such that the keel can be raised by upward translation at least partly into the keel-storage space of the conning tower.

A marine monitoring and debris collection scow is provided, the scow comprising: a hull which includes an open stern, a bow opposite the open stern, a deck extending between the open stern and the bow and forming a bottom on an underside, the bottom extending between the open stern and the bow; a frame, the frame which is attached to the deck, the frame including a front, a back which is opposite the front and sides extending between the front and the back; at least one flotation chamber which extends around the sides and the front of the frame and forms a gunwale; a housing mounted on the deck; and a microcontroller unit housed in the housing, the microcontroller unit configured to receive a data set from at least one sensor, to store the data set, to process the data set into a processed data set and to send the processed data set to a radio.

A slide system includes a component assembly, a track system, a floor panel, and a below-deck cavity. The track system is coupled at least indirectly to the component assembly for guiding movement of the component assembly along a path. The floor panel includes an upper surface. The below-deck cavity is disposed below the floor panel. The component assembly is located substantially above the floor panel. The track system is located within the below deck cavity and below the upper surface.

A watercraft comprises a hull, a deck disposed on the hull, a motor connected to at least one of the hull and the deck, a propulsion system operatively connected to the motor, a command console disposed on the deck and operatively connected to the motor, an accelerator control lever operatively connected to the command console, and a control unit operatively connected to the command console and to the motor. The control unit receives, from the command console, a value representing a current position of the accelerator control lever, controls an operating parameter of the motor based at least in part on the current position of the accelerator control lever, receives, from the command console, a cruise control enabling signal, and in response to receiving the cruise control enabling signal, selectively engages a cruise control function of the watercraft by maintaining the operating parameter of the motor.

An adjustable frame configured to detachably connect to a backrest to allow the backrest to be transitioned between two or more angular positions relative to a horizontal plane, with at least one position being more upright and at least one position being more reclined. The adjustable frame may include a turret rotatably positioned on a base socket, the rotation of the turret from one position to another on the base socket causing the backrest to be held at a different angular position.
