Summary Crewmember fatigue and shiftwork practices continue to be matters of concern for many navies and have been a recent topic of investigation. From our research, we know that certain watchstanding schedules, especially those that do not align with human circadian rhythms, exacerbate existing crew fatigue problems, extend the length of working hours, and degrade crew performance. Over the last fifteen years, we have studied the work and rest patterns of US Navy Sailors in a variety of shipboard operational environments. However, to provide better insight about the effect of shiftwork at sea, we still need to collect data on a number of other watchstanding schedules. This study will provide funding necessary to collect data from multiple watchstanding schedules and allow us to fill gaps in our understanding of sailor performance and its relationship with watchstanding schedules used in the U.S. Navy.
