The influence of the vertical prismatic coefficient of the forebody on the ship motions in waves was investigated. Ship motions and hydrodynamic coefficients were calculated for the ship models with three values of block coefficient. Inside each model family the vertical prismatic coefficient has three values, which leaded to the change of forebody cross-sections from U-shaped to V-shaped form. The models with V-shaped forebody appeared to have advantage in heave in all waves, while pitch was reduced in long waves and increased in short waves. This was caused by the difference in distribution of sectional added mass and damping along ship’s length.
