Method of steering aquatic vessels

摘要

There is provided a boat ( 200 ) including a hull ( 20 ), and two engines ( 30, 50 ) couplable to rotationally drive mutually spaced separate corresponding propeller assemblies for providing thrusts. Directions of the thrusts are angularly adjustable (alpha₁, alpha₂) relative to the hull ( 20 ). A control unit ( 70 ) receives first and second user commands (S₁, S₂) and sends corresponding signals for controlling powers (P 1, P 2 ) coupled from the engines ( 30, 50 ) to their propeller assemblies. The control unit ( 70 ) determines a difference in power (DeltaP) to be coupled to the propeller assemblies as a function of the first and second user commands (S₁, S₂). The control unit ( 70 ) controls coupling of power (P 1, P 2 ) to the propeller assemblies so that the propeller assemblies develop a difference in thrust which is a function of the difference in power (DeltaP). The control unit ( 70 ) adjusts angles (alpha₁, alpha₂) of the directions of thrusts as a function of the difference in power (DeltaP) to assist the difference in power (DeltaP) coupled to the propeller assemblies to enhance maneuverability of the vessel ( 200 ).
