Hello Jeff, You will find details of a British wind and water generator at www.boost-energy.com/ampair/products_product4.asp This is for a towed propellor. The actual generator is a first class product, I know because I had one in the wind driven form. It was mounted initially just above the Radar on the mizzen of my awful Oyster 435 and did not work when the mizzen staysail was hoisted. It was fine when relocated at the top of the mast but now lies on the bottom of Newport R.I. harbour thanks to Hurricane Bob. There is another British maker of a wind/water generator which looked better but I cannot trace them. Before you get too involved in fitting a shaft driven generator check with your engine/gearbox maker that it will not wreck the gearbox. This happened to someone we met in the Pacific and the reason was that there was no pressurised oil supply to the gearbox unless the engine was running. He was assured by his favourite mechanic back in the States that there would be no problems and he continued to let the shaft freewheel with his next gearbox !!! and it was not even driving a generator. That showed great faith in that mechanic or was it stupidity?
