Title:
VESSEL
Document Type and Number:
Japanese Patent JP2021116011
Kind Code:
A
Abstract:
To improve fuel consumption when having stance of a vessel attain a target angle.SOLUTION: A vessel includes: two propulsion generating devices 113L, 113R respectively provided to both sides of a hull; a steering mechanism 115 for controlling turning of the hull; a turning command acquirement unit 103 for acquiring a turning command value including a turning direction and turning amount; a velocity acquirement unit 107 for acquiring a velocity command value for the hull; and a turning controller 111 for turning the vessel according to a turning command value by having the steering gear 115 be in a neutral position as well as controlling the two propulsion generating devices 113L, 113R so that the propulsion force of the propulsion generating devices 113L, 113R inside the turning direction is smaller than the propulsion force of the propulsion generating devices 113L, 113R outside the steering direction when the velocity command value acquired by the velocity acquirement unit 107 is the velocity threshold or more.SELECTED DRAWING: Figure 1
