Abstract

Design procedures for high speed craft are currently centred on performance and structural considerations. However, improvements in craft performance have led to crew frailty often being the limiting factor for high speed operation, particularly offshore. This has resulted in the re-evaluation of the primary design considerations to centre the design process on human capabilities.
In this paper a systematic procedure is developed to enable direct correlation between numerical, or model-scale, motion data and human responses in the full scale craft. The nature of different modes of motion and their specific effects on the performance of a vessels crew is analysed in both a quantitative and qualitative manner. This investigation has identified the factors most detrimental to crew endurance and their performance posttransit.
A procedure for measuring human responses to full scale vessel motion, enabling real time measurements of crew reactions to be made, is described. Also presented is the data acquired for both a wave-piercing RIB and a conventional hard chine form, including measurements of sea state, vessel motions, seat motions and human responses. This approach allows direct correlation between physiological and psychological responses and the sea conditions in each case.
