The concept of augmenting the inherent damping of a lighter hull to suppress its heave response in waves, and thereby to reduce relative motion between a cargo ship and lighter is the subject of investigation. The scope of the effort was a minimum one to rapidly assess the promise of the concept. A primarily empirical approach was taken. Sufficient analysis was included to interpret the test results and to consider the implications of the results in full scale. Model tests were performed in a model basin with wave making facility. The model consisted of a one-sixth scale hull for a 45 ft. long patrol boat with its damping appendage slats, one or two high, longitudinally aligned on either side. (Author Modified Abstract)
