Aiming at the safe navigation problem of sailboat under different wind forces, the heading stability of sailboat under uniform wind was studied based on a mathematical model with three degrees of freedom. Taking a 12m-type sailboat as an example, the balance between the aerodynamic force and torque on the waterline with dynamic and torque under the water line was theoretically analyzed. The wind speed boundary and controllable area of the sailboat in wing at the different sail angles under the different rudder angles were calculated. According to the calculation results, the factors which affect the controllable area of sailboat and the relationship between the sailing parameters in the area were analyzed. A reasonable sail rubber control suggestion was also proposed to enhance resistance to wind of the sailboat, which can provide theoretical guidance and data reference for sailboat drivers to control sail and rudder according to the different sea conditions.
Key words: sailboat; mathematical model; uniform wind; wind speed boundary; controllable area
