A thuster control unit which in general comprises a base plate 100, a switch panel 200 mounted on said base plate, and a boat shaped, or navicular, control knob 500 mounted on the base plate such that it is displaceable over the switch panel. The panel is equipped with switches, such as embedded switches, for controlling bow and stem thrusters, and/or any other propulsion unit. The control knob is equipped actuator pegs 425, biased downwards, each thus transmitting a force to the switch panel. In a non-actuated state, the navicular control knob remains in a neutral position in which position no one of the embedded boat manoeuvring control switches are operated. The forward and aft actuator pegs thus activate the forward and aft boat manoeuvring control switches respectively in a manner corresponding with a selective displacement of the navicular control knob. The boat shaped control knob provides a novel, efficient and reliable means for a combined control of any boat propulsion system.
