This next version of the ROCAT became known as 'proto 2' – the majority of the sea trials were carried out in this boat, and it served very well.

Meanwhile, it appeared on the Concept Boat 2002 stand at the 2003 London Boat Show, and on the ROCAT stand at the Boat, Caravan and Outdoor Show at the NEC. After it had outlived its useful developmental life, it then became the '2004 Feature Boat' at the National Maritime Museum, Cornwall.
