In 1975 I persuaded Hugh to lend me the wind generator to see if it would produce enough APD to run the lights aboard Iolaire, my 1905 46-foot engineless yawl. He mounted the wind generator on Iolaire's mizzen masthead so it would be as high as possible and allow me to use the mizzen staysail. That year Iolaire did a double transatlantic, along with the Fastnet, La Rochelle, La Trinité, and the Bénodet and Solent races.
Iolaire arrived back in Grenada having sailed 13,000 miles in seven months with the wind generator providing enough APD to run her lights. This proved to Hugh that he had, with development, a commercial proposition.
Hugh and the British company Ampair developed the Ampair 100, one of which was on Iolaire's mizzen masthead from 1977 until 2008, when Ampair gave me one of its new 300-watt wind generators.
