A control system for controlling movement, position, or force for a mechanically connected object comprising a plurality of marine vessels. The control system includes at least one processor configured to: receive a movement, position or force command for the mechanically connected object; and generate at least one first command for a first marine vessel of the plurality of marine vessels and at least one second command for a second marine vessel of the plurality of marine vessels, to control movement, position, or force of the mechanically connected object in response to the movement, position or force command for the mechanically connected object.

Disclosed is a marine and freshwater debris collection system using drones and a method for collecting debris using the same. More specifically, the invention allows for the faster and more efficient collection of debris in marine and freshwater environments through the use of drones. In particular, the drones approach a target point, launch a net, and a net hoisting and retrieval hook is used to hoist the trapped debris onto the vessel. This entire process is automated or semi-automated, thereby maximizing the efficiency of the debris collection operation.
