As part Phase II of a continuing program for establishing habitability design criteria for a large scale Surface Effect Ship SES, 19 novice U.S. Naval enlisted personnel were exposed to motion for periods up to 48 hours in a closed cabin mounted on a three-degree-of-freedom simulator the ONR HFR Motion Generator. These subjects were variously exposed to eight conditions of full-amplitude or attenuated SES motion, representative of fully developed starboard bow seas traversed at high speeds i.e., Sea State 3 at 80 kt, Sea State 4 at 60 kt, and Sea State 5 at 40 kt. The results described here were obtained from 16 of these subjects, who were exposed to one or more motion conditions, and who provided comparable data during confinement in a similar, but static, cabin environment. The results pertain to the subjects cognitive or visual functions, physiological stress, and sleep. Other aspects of their reactions to motion are described in companion volumes of this series.
