It is known that sleep deprivation is a frequent problem when assessing performance at sea (Miller, Matsangas, & Kenney, 2012). To the extent that some factors leading to sleep deprivation can be controlled in the operational environment, models of predicting performance can be a useful tool to optimize work and rest schedules, and hence have a better-rested crew. What distinguishes the naval operational environment from other environments and what truly characterizes life at sea, however, is not the human need for sleep; it is environmental motion. Biodynamic effects of motion can impair postural equilibrium and motor skills (Matsangas & McCauley, 2013; Matsangas, McCauley, Gehl, et al., 2014). Indirect effects like motion sickness and sopite syndrome not only lower our motivation to work but can also lead to temporal or complete abandonment of assigned duties (Hettinger, Kennedy, & McCauley, 1990; Lackner, 2014; Matsangas, McCauley, & Becker, 2014).
