Abstract : Previous studies have shown that motion sickness has a significant effect on a percentage of ship crews, especially during the early phase of the deployment (the first three days). This research examines the primary watchstander assignments onboard the Littoral Combat Ship (LCS) platform to ascertain the effects of motion sickness on crew manning, proficiency of work, and indicators of reduced effectiveness in carrying out operations. Potential degradations in performance or in quality of performance due to symptoms of motion sickness were correlated with 36 primary watchstander assignments typical of the tasks necessary to carry out the various operational aspects of the LCS. The results were tabulated and formed into a Figure of Merit (FoM). Performance quality was divided into five categories: making decisions, analytical tasks, reading, fine motor skills, and gross motion, each contributing equally to the FoM considered for manning and operations. By correlating the FoM with the watchstander assignments, the degree of impairment for each assignment was assessed. The results showed that 6 out of 36 watchstations had four different performance qualities affected by motion sickness. The results illustrate the reduced operational effectiveness of watchstander performance based on various sea conditions (calm, moderate, and heavy).
