An attempt is made to establish a simple method of calculating stopping ability of ships as expressed by head reach. The deceleration of a ship is determined by means of one dimensional equation of motion, by abandoning the attempt to satisfy the equation for the rotating system of engine-propeller combination. Assumptions are made that total resistance R is proportional to the square of the velocity and the constant astern thrust T_1 is instantaneously applied which is taken to be value at dead-in-the-water. The final equation of motion of ship can be expressed in the form T_s(dV)/(ds)+V=-K_sn_1^2,and head reach can be obtained as S=T_slog_e(1+1/(K_s) (V_0)/(n_1^2))Thus if T_s, which is essentially the hull characteristic, and K_s, which denotes the propeller characteristic, are given, the corresponding head reach can be easily calculated.
