For a number of years now the Royal Dutch Lifeboat Institution (KNRM) satisfactorily utilize fast Rigid Inflatable Boats (RIB's) for Search and Rescue (SAR) purpose. These aluminum RIB's, fitted with a rubber tube, have a length of around 15m. and a displacement of about 14 tons. Two 500 kW main engines combined with a waterjet propulsion give these boats a calm water speed of 34 knots. These boats are 'All Weather' and have an endurance of 200 nm in calm water. However, good these vessel may be, the KNRM still wishes to improve their SAR RIBs. The actual speed that a rescue boat can maintain in seaway is dependent on the acceleration level felt by the crew on the bridge. The lower this acceleration level, the higher the operability of the boat. In order to decrease this level of acceleration, a new design for a SAR RIB for the KNRM was made using the Enlarged Ship Concept (ESC). This was accomplished in the following two steps: Firstly, computations were made to assess the expected resistance and ship motions advantage's using the non-linear program Fastship of the Delft Shiphydromechanics Laboratory.
