A system for controlling a watercraft includes a bow thruster, an outboard motor being an only outboard motor attached to the watercraft, and a controller. The bow thruster includes a port oriented in an obliquely forward direction of the watercraft to jet a stream of water in the obliquely forward direction of the watercraft. The outboard motor is attached to the watercraft to be steered right and left. The controller is configured or programmed to control the outboard motor and the bow thruster to cause the watercraft to move sideways by a net force of a first thrust generated by the bow thruster and a second thrust generated by the outboard motor.

An intentional fluid manipulation apparatus (IFMA) assembly with a first thrust apparatus that imparts a first induced velocity to a local free stream flow during a nominal operation requirement. The first thrust apparatus creates a streamtube. A second thrust apparatus is located in a downstream portion of the streamtube. The second thrust apparatus imparts a second induced velocity to the local free stream flow. The second induced velocity at the location of the second thrust apparatus has a component in a direction opposite to the direction of the first induced velocity at the location of the second thrust apparatus.
