An expansion deck system for vessels includes a frame assembly for positioning between a stationary floor of a vessel and a plurality of pontoons of the vessel. The frame assembly including a first side with a first elongated opening, and a second side with a second elongated opening. One or more sliding deck members are telescopically connected to the frame assembly by one or more sliding rails and transition between a retracted position and an extended position. In the retracted position the one or more sliding deck members are positioned between the floor and pontoons of the vessel, and in the extended position the one or more sliding deck members are positioned alongside the frame assembly.

An autonomous sailing vessel may include a hull, a mast, a sail, and a rudder. The mast may be mechanically coupled to the hull. The sail may be mechanically coupled to the mast. The rudder may be mechanically coupled to the hull. A heading of the autonomous sailing vessel may be regulated by actively controlling the rudder without actively controlling the sail. Alternatively or additionally, the autonomous sailing vessel may include an anticapsize stabilizer tank, a lidar system, and/or marine mammal monitoring and identification.

An assembly with a first coupling having a forward bulkhead device is provided. The forward bulkhead device contains a first connector insert having first end connections for wires and optical fibers of an acoustic array. The assembly also includes a second coupling having an aft bulkhead device therein. The aft bulkhead device contains a second connector insert having second end connections for the wires and optical fibers of the acoustic array. The forward bulkhead device further includes an alignment assembly. The alignment assembly is matable with the aft bulkhead device to align the first connector insert with the second connector insert. The forward bulkhead device further includes a locking ring connecting the forward bulkhead device with the aft bulkhead device.

A watercraft light adapted to fit in a rub rail is provided. The watercraft light longitudinally extends in a portion of the rub rail and provides light to the exterior of the watercraft. A watercraft light system and method of installing the watercraft light are also presently disclosed.

A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around one or more of its roll, pitch, and yaw axes which affects the quiet regions in the wake. A gyroscope supported in the hull may be used to rotate the hull around one or more axes. Such rotation may be used to create a surf left and/or surf right configuration, and measured via one or more sensors. Other systems and methods are also provided.
