However, the stability performance of the non-traditional ship type is greatly different from that of the conventional ship type due to the characteristics of the non-traditional ship type, the restoring moment is obviously reduced when the ship body inclines compared with the conventional ship type due to the inward inclination design, particularly the restoring moment is generated when the ship body inclines at a large inclination angle, the deck of the inward inclination ship type is seriously wavy, and sometimes the whole bow part can be buried in waves to cause great stability loss. Therefore, under the condition of high sea, the overturning risk of the inward-inclined ship type is obviously greater than that of the conventional ship type, and the stability problem becomes a key for restricting the application of the inward-inclined ship type on a surface ship.
