A comparative evaluation of the seakeeping capabilities of a 64-foot SWATH craft and a 65-foot monohull was conducted by the Naval Biodynamics Laboratory, New Orleans, Louisiana, during a two-day period in November 1984. The trial was conducted at the mouth of the Columbia River, Astoria, Oregon. The seakeeping trials measured the hull motions of the two vessels during comparable sea conditions. These conditions approximated the maximum environmental conditions under which the vessels would normally be expected to conduct hydrographic surveying missions. Measurements of pitch, roll, and vertical and transverse acceleration of the hydrographic surveying missions. Measurement so pitch, roll, and vertical and transverse acceleration of the hydrographic crews work station were obtained for each vessel. The seekeeping trials indicated that the SWATH hull provided a significantly more stable platform from which to conduct hydrographic surveying missions when the human operator is considered. Compared to the monohull, the SWATH hull can be expected to reduce the overall incidence of motion sickness and to improve human performance.
