A new navigation-assisting sail is designed based on the sail’s angle of attack and attitude to realize wind direction tracking. Based on the boat’s state and environmental parameters, combined with a given database, the motor is used to drive the ball screw to realize self-adaptive control of the sail’s angle of attack. Intelligent control of the sail effectively increases the utilization rate of wind energy during sailing and provides a new solution for ship energy saving and emission reduction.
