The bow configuration of the tumblehome hull has a certain influence on the motion and the characteristics of green water loads in waves. In this paper, based on the inclination angle of stem, three kinds of bow configurations with inclination angles of 30°, 45° and 60° were selected. The motion response of the tumblehome hull in regular waves and the load characteristics of green water were studied by using the CNT-CGFDM method. The simulation of object boundary and motion was realized by immersed boundary method, and the free surface was captured by THINC/SW method. The ship models with 45° and 60° inclination angles of stem were selected for model test. The numerical simulation results are in good agreement with the experimental results. The results show that the bow configuration has little effect on the motion response of the tumblehome hull in regular waves, and show that some local differences exist only in some sea conditions. It has a certain influence on the slamming load of green water on the tumblehome hulls. Compared with the configuration scheme with the inclination angles of 30° and 60°, the load performance of green water on tumblehome hull with the inclination angle of 45° is more excellent.
