A nonlinear second order ordinary differential equation in yaw rate is used to study the directional stability of a surface ship when the ship moves with randomly varying forward speed. Randomly varying forward speed may be caused by surge motion in random following (or oblique) waves. A stability criterion is developed and stability loss is found to be related to the power spectral density of forward speed.
