A comprehensive program of model experiments and computer simulation studies was carried out to investigate the shallow-water maneuverability characteristics associated with the MARAD Series for large full-form merchant ships. The investigation was based on the use of four existing Series models (ranging from 20 to 26 feet in length) which combine to represent B/T variations of 3.00, 3.75, and 4.50 with constant L/B = 5.00 and C sub B - 0.85, and L/B variations of 5.00 and 6.50 with constant B/T - 3.00 and C sub B - 0.85. The experiments were all performed with the new HSMB LAHPMM System using standard techniques, adapted as necessary to meet shallow-water requirements, and covered a range of constant depth-to-draft ratio H/T values down to 1.2. The results of the overall investigation are presented in handbook format, suitable for direct use by naval architects and other practitioners, both in nondimensional form and in terms of their application to "standard-ship prototypes" having a full-load displacement of 200,000 tons.
