Steersman Self Steering system for yachts

A mechanical device which steers a yacht using the changes of wind pressure in the sails. The system has been tried and tested and has appeared in many yachting magazines. I have also won award for this invention which was presented to me by Sir Robin Knox-Johnson, the first person to circumnavigate the world single handed with out stopping. Several people have bought the unit in both the US and South Africa.
