This famous yawl-rigged yacht was built in 1875 by E H Bentall. She was a radical departure from the accepted racing yacht design. His intention was to build a yacht with the 'longest waterline, smallest frictional surface, and shortest keel'. The design eliminated deadwood fore and aft. She was 110 ft 6 ins in length, 16 ft 7 ins in breadth, and had a draught of 13 ft 7 ins. A yawl is a sailing vesel with two masts, the front one being the taller, and the aft mast being sited behind the steering position.
