Description/Abstract

The motions of high speed marine craft can be uncomfortable and damaging, with detrimental effects on the operation(s) of the craft. The motion exposures can reduce crew and/or passengers abilities to perform tasks, during and after transits. This is especially of concern for military and/or rescue operations and means to reduce or mitigate against motion exposures are required for improving both performance and safety. Current efforts to mitigate against motion exposures of high speed craft include isolating the occupants from the externally induced disturbances, however methods to isolate the occupants from the motion exposures may have limitations. This paper describes the hazards of whole body vibration and provides an overview of the effects and affects of the motions of high speed craft, including a discussion of the human factor considerations and motion mitigation strategies for high speed marine craft.
