A Mariner class ship model vas tested at various shallow water depths and Froude Numbers constrained to motion in one degree of freedom, either pitch-no heave or heave-no pitch. Under these constraints, using a step response technique 5 the response of the model to a step disturbance in pitch or heave was recorded* This response was then analyzed to obtain virtual mass or virtual inertia and damping coefficients in heave and pitch. These results are presented to show the effects of shallow water on these ship motion parameters at various Froude Numbers as a function of frequency of oscillation.
