Abstract: An unmanned, remotely controlled modular vessel that is capable of deploying and retrieving a crustacean fishing cage or “pot.” A derrick structure is supported by two modular rigid pontoons and is interconnected to equipment deck plates that contain: a motor for propulsion, a winch for lowering and raising a cage suspended centrally from a pulley mounted underneath the top of the derrick, a receiver electronics module inside a waterproof enclosure, and a pair of rechargeable marine batteries. The derrick structure also provides elevated mounting points for a receiving antenna and a beacon light for use during night hours. The system is operated from the shoreline by the user, who manipulates the controls on a wireless transmitter, triggering the various on-board functions necessary to fulfill the intended mission: to catch and deliver fresh crustaceans to the user.
