How Maritime Organisations Can Develop a Holistic Approach to Shock Mitigation By All Means

The definition of shock mitigation is, 'to make a violent collision or impact less intense'. A shock mitigation strategy is essential for all craft that undertake open sea transits or operate in rough water. This includes rivers and estuaries with wind against tide conditions which form waves. Since the 1990’s, focus has mainly been on developing mechanical suspension seats to reduce the effects of vertical accelerations. Areas considers areas requiring further investigation include fore-aft, lateral and vector forces, plus improving seat cushion performance and comfort.

A challenge for the builders of next generation RIBs and high speed craft is delivering platforms that balance high performance with the physical demands on crew and passengers. With the arrival of ‘unbreakable boats’ plus a surplus of engine power ‘man’ is often considered the weakest link. CAD software and digital modelling are key components in the process of designing high speed craft, but feedback from the human body is crucial input that designers and naval architects must consider for the next generation of fast boats. The objective of this paper is to bring together a body of information that end-user organisations and industry can utilize in order to develop a holistic approach to shock mitigation on fast boats.
