No need to raise my voice. More than a few boat lengths away and it is completely silent (this, based on me going around and asking anchor mates ó most were even unaware we had a windgen).

I considered a D400 and a SW350 when making my decision. Both seem like excellent choices for noise and output. I would have gone with a D400, but it is a lot heavier, and quite a bit more expensive. I forget why I didnít choose the SW350 ó price perhaps...
The SuperWind is about $400 more than the D400. But you do get what you pay for in a SuperWind350.

Re: 2018 Wind generators

I have the Rutland 1200. Mounted on 2.7m post secured to my transom arch with a rubber-bushed mounting kit available from Silentwind. In the UK the kit is marketed by Allspars . I got the Rutland, 3 x 50W solar and MPPT controller from Marlec Engineering, UK. The controller handles both wind and solar. The Rutland starts producing at about 8 Kn of wind. Reaches max out put at 30kn above which it has an automatic shut-down. Very quiet. A friend of mine has the Silentwind but did not use any rubber-bushed brackets. A bit noisy in the cockpit and loud humming in cabin directly beneath the deck with mounting. So noisy he turns it off when he want to sleep. That rather looses the point of a windgen since it could be producing energy at night when solar has stopped. About 50% of the paint on his Silentwind has peeled off after 4 years in the Med.

What kind of amp output are you seeing at 18 knots?

Re: 2018 Wind generators

Wind generator are efficient for navigation at night . Solar panels is the first choice of most cruisers, even those that already have a wind generator shut it down in Anchorage in the Caribbean.
The installation cost is something not to be forgotten.

I never turn mine off. Can't hear it so no need to reduce charging.

Re: 2018 Wind generators

I think Marley show ŗ graph on their website across complete wind range. An optional extra is a small remote display which you can put at the chart table somewhere. Gives the voltage of your 2 battery banks, instantaneous power from each of solar and wind, plus accumulated amps & watts for each. In the Med i find i get 90% of the power comes from the solar.

I had exactly the same problem with my 2 SilentWind generators and I had the rubber-bushed brackets. The noise was mostly from unbalanced blades. After balancing (and using blue locktite on everything), the noise would be reduced for a week or two. Also, my generators had defective bearing and casings from the factory... The replacement assemblies were better for a couple of months. Very poor quality control. The factory authorized Silentwind dealer/installer who came to troubleshoot was absolutely no help at all. He said my installation was fine, which meant that the Silentwind gens suck...

I would also turn them off at night to sleet. Very annoying.

The paint peeled of after 2 seasons on mine.

Never again...

Well, like I said, six years with zero problems. I guess Iím lucky. I do think the noise thing is about the mounting.

BTW, I even made a video of my Silentwind running while I was sitting in the cockpit. Itís in another wind gen thread.

You are lucky! Mine had manufacturing defects but the replacement parts made little difference. The Silentwind rep said my installation was fine and that it was normal to have noise & vibration... I guess they did not want to take responsibility for two crappy gens. I gave up.
Next time, I am getting the D400.
