wind

They make a tremendous racket. I wouldn't want one.

I have one. I don't bother putting it up during the summer as my 375w of solar more than provides all the power I need. Come October I assemble it. It lives on an aluminium scaffold pole with fittings welded to the hand rail at the back of the cruiser deck.

You need to be moored in the right spots to get much out of it. If there are trees around these deflect the wind rendering it pretty useless. In the right spots though it delivers a couple of amps when there's a fresh breeze.

In terms of cost and returns it's a no brainer, don't bother! Personally though I like them, wouldn't be without mine.

The turbine I had in 2000 was an aero gen 6. Big one I bought secondhand . I regularly saw over 15 amps out of it into 12v. I got fed up of folding it for bridges. In the last 10 years some lighter units with more advanced electronics have come out but I'm not sure if they are any better.

2 amps must be a very small unit?

I got 2 rutlands 913's wired together into one regulator. one day seen a big flash in boat lol .It was the 20amp fuse blown in regulator panic panic.yes but it was gale forse winds.must say my turbines have been brilliant and kept me going in winter Wen theres been no sun for months like 2014/13 floods .People say turbines vibrate your boat. Mine don't and I'm on a small cruiser.only time I've felt vibrating is wen the bearings are going and you will definitely know about that. but that's sorted now. oh and if they ever free wheel (meaning if a wire comes off battery terminal they are very noisy but thats a wind noise panic panic simple to mend. stop turbine first.reconnect cable to battery

Apparently the new Rutland 900 series (914) has an mppt controller and 30% more output (in theory).

I had a Rutland 910 about 20 years ago but I found the bearings went really quickly leading to excessive droning. I think its because the rotor is heavy which puts a lot of load on the bearings. They may have sorted that by now.
