This study examines in an operational setting the hypothesis that human performance is significantly affected by ships roll. Particular attention is paid to the nature and effects of roll stabilization equipment. The hypothesis is expanded to include the broad spectrum of human performance and the more subtle aspects of ships motion. Notable findings include 1 Ship motion causes an irrelevant stress on crew members. 2 Some irrelevant stress may actually be beneficial. 3 The effect of roll stabilization equipment is diphasic it reduces intolerable roll amplitudes but tends to induce higher linear accelerations. 4 Roll stabilization should be active from dead-in-water through flank speed since mission requirements include extensive operations at low speeds.
