Fourwinds trailing generator

Has anyone ever heard of this? What is it and how does it work?

I've heard of a fourwinds wind generator, but never a trailing generator. Do you mean a water-generator where the generator is towed or a fuel-powered genset?

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

It is a wind generator that has a special blade and mount so you can stick it in the water and use it that way, Dog. I can't quite figure out why this seems so wrong, but it does, just thinking about the drag and torque on that mounting arm gives me a headache.

The DuoGen is pretty well regarded. The torque on the mounting arm isn't all that bad, and the drag is reasonable.

Look at Wind Powered Generators

Ferris uses the same generator for wind and water power.

Ampair/aquair do one. CLICKY

I had one on my previous boat and it served me well for seven years. On passage towing at 5 knots I got 4 amps and at 6 knots 6 amps I don't know what we got at 7 knots as I was too busy taking some sail down.

At anchor I hung it in the rigging and got some power quietly. It produced less using the wind than other wind generators like the Kiss, 4 Winds or the Air Marine.

I used to avoid anchoring next to 4 winds as their overspeed device was unbelievably noisy when it cut in.

SD, In your experience do you think this equipment could work? If it was on your boat would you keep it or toss?

IT was on a friend's boat and she still has it. Works quite nicely.
