Resumen

The surveyboat Rodolf is the result of the Portland District’s efforts to improve the efficiency of hydrographic surveys and use the full capabilities of electronic equipment. The Rodolf is an example of surface-effect-ship (SES) technology, the concept of an air-cushion supported vessel with rigid side hulls combined with the latest survey technology. With air-cushion assist, up to 80 percent of the vessel weight is supported by air pressure. Approximately one year of operating experience has been accumulated with the Rodolf in the Portland District. The air-cushion assist principle has proven itself to be a valid concept for use as a high speed surveyboat. Supporting most of the vessel weight with an air-cushion is a fuel efficient method of attaining high performance with reduced propulsion power requirements. Survey speeds of 22 knots are attainable with the Rodolf. Handling and maneuvering characteristics are similar to regular planing hulls in many ways.
