Abstract
Historical perspective and previous studies have shown motion sickness has a significant effect on some percentage of ship crews, especially during the early phase of the deployment. This research examined 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 thirty-six 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). The performance and performance quality were divided into five categories: making decisions, analytical tasks, reading, fine motor, 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 watchstander was assessed. Six out of thirty-six watchstations had four different performance or performance qualities affected by motion sickness. The results illustrated the expected and reduced operational effectiveness of watchstander performance qualities based on various sea conditions (calm, moderate, and heavy).
