| HISTORY | Purchased as an electric launch, but Sylvia’s good idea of combining steam and electric resulted in this dual fuel boat. Changeover from steam to electric is via a lever operated (Sam Wilkinson design) dog clutch anchoring the required engine to the prop shaft. To March 1998 cruised well over 1000 miles in England and France.
