Peter Worsley's Rotary Craft is in the background behind Robert Downhill. Robert appears to be guarding the lunchtime sandwiches.

Peter Worsley sailed his Rotary Sailing Craft. It was fascinating to watch this craft make steady forward progress whilst sailing directly into the wind.

The following pictures show various views of Peter's boat. The 'windmill' drives a belt which in turn transmits power to the water propeller via bicycle gears.

Robert Downhill was the first to be interviewed by the BBC Tomorrow's World team.

If anyone knows any of the history and development of this craft Patrick Mayne 

In the right of the picture Slade Penoyre can be seen sailing his modifed catapult.

This is Jim Crafer's model of his Eco-Ranger design.

Nick Povey about to try his 4 metre sailboard for the first time. As the board accelerates it rises up onto the planing surfaces seen beneath it.
