1. A method of maneuvering an aquatic vessel, said vessel including at least one hull and at least one engine, said at least one engine including at least one output rotationally couplable to a plurality of corresponding propeller units which are mounted so as to be angularly moveable in respect of said at least one hull, said aquatic vessel including a control unit for controlling operation of said at least one engine and angles of said propeller units with respect to said at least one hull, said aquatic vessel being configurable to operate in a first mode wherein directions of thrust developed by the plurality of propeller units are mutually substantially parallel for propelling the vessel through water, said method comprising the steps of:

  • user-instructing the control unit to invoke a second mode of operation wherein said directions of thrust developed by said propeller units mutually diverge angularly with respect to a longitudinal axis from a rear end of the vessel to a forward end thereof for providing the vessel with a turning characteristic; and

    controlling rotation of the vessel by controlling power coupled from the at least one engine delivered to said plurality of propeller units and controlling forward/reverse coupling of said propeller units.
