the problem that the ship 100 is easily influenced by sea waves and sways in the process of sailing of the existing ship 100 is solved through the first stabilizer 300, the position of the stabilizer 305 on the ship 100 is adjusted through the translation assembly 304, the problem that the existing stabilizer cannot be adjusted according to the sailing condition of the ship 100 is solved, and the problem that the existing stabilizer cannot be adjusted according to the sailing condition of the ship 100 is solved through the fixed fin 315, the movable fin 319 and the adjusting fin 320;

When the swing reducing member needs to be moved at the position of the ship 100, the first cylindrical motor is started, the first cylindrical motor drives the rotating shaft 308 to rotate, and the belt pulley 310 rotates, so that the rotation of the belt pulley 310 is converted into the linear motion of the supporting block 311 on the sliding rail 302, and the function of adjusting the position of the swing reducing member is achieved; the belt 312 is always kept in a flat and tight state by the translation spring 313.

when the area of the anti-sway part needs to be changed, a second cylindrical motor is started, the second cylindrical motor drives the pin handle 316 to rotate, the adjusting rods 318 rotate along with the pin handle 316, the driving pin 321 is always positioned between the two adjusting rods 318 and is always abutted against the two adjusting rods 318 in the rotating process of the adjusting rods 318, the adjusting rods 318 stir the driving pin 321 to move along the driving groove 326 under the acting force of the adjusting rods 318, and the moving fin 319 moves along with the driving pin 321; when the pin handle 316 rotates clockwise, the driving pin 321 moves in the a-section 322-b-section 323-c-section 324-d-section 325 in sequence, and the driving pin 321 moves in the driving groove 326 for one adjustment cycle for each circle, and the movement of the moving fin 319 is as follows: moving toward the supporting block 311-rotating 90 ° counterclockwise-moving away from the supporting block 311-rotating 90 ° clockwise, i.e. the moving fin 319 is folded in the fixed fin 315-the adjusting fin 320 is perpendicular to the X-axis-the moving fin 319 extends out of the fixed fin 315-the adjusting fin 320 is parallel to the X-axis. The roll reduction assembly 305 can have the following four modes, and the user can make adjustment selections as needed:

firstly, the movable fin 319 is folded in the fixed fin 315, and the adjusting fin 320 is parallel to the X-axis;

the moving fin 319 is folded in the fixed fin 315, and the adjusting fin 320 is perpendicular to the X-axis;
