Abstract : Three seagoing box scores applicable to any vehicle operating on the surface of the ocean are defined and assessed. One of the box scores is directly useful for calculating the operational worth and the technical seagoing merit of vehicles performing ocean surveillance-like functions. The second box score is similarly useful for the ordinary transportation function of vehicles. The third box score is useful for measuring the technical seagoing merit of vehicles performing any function. This work brings together prescribed values of 18 seakeeping criteria for monohulls, small-waterplane-area twin-hull (SWATH) ships, planing craft, surface effect ships, and air cushion vehicles from sources indicated in the report. The nature of each criterion is discussed and the prescribed values of these 18 criteria for each vehicle type are compared and discussed. Although some of the prescribed values of these 18 criteria are not reconcilable, other values, obtained from independent sources, show remarkable agreement. At least one new criterion not included in Table 2 is needed for monohulls.
