Abstract : Development of the HYDRA Survey System family of lightweight automated hydrographic data acquisition systems by the U. S. Naval Oceanographic Office (NAVOCEANO) has in turn generated a new requirement for an advanced family of survey platforms. To take full advantage of HYDRA's high density recording capabilities, an effective stable platform suitable for housing such equipment and operating at speeds in excess of 40 knots is essential. Those platforms showing the most promise are hydrofoils and sidewall hovercraft. NAVOCEANO has participated in several demonstrations of commercially available hovercraft and hydrofoils in addition to conducting a series of trials of its own. To date sidewall hovercraft have shown more potential as survey platforms owing to their greater range of efficient operating speeds. The intent of this report is to discuss the unique characteristics of a 51-foot sidewall hovercraft recently tested off the English Coast. This particular craft was completely fitted out with automated hydrographic data acquisition and survey control instrumentation. (Author)
