I am intending to install a Rutland 914i windcharger.
I have started making the stainless steel pole, base plate and bracing arms.
I see in some discussions people have a problem with noise transmitted into the hull.
I will use 4 mm insertion rubber under the base plate.
And if I find noise transmits I will then cut the 1"diameter S/S bracing arms and join them with a rubber hose clamped each side of the cut.

Does this seem like a reasonable way forward with the installation?
What have other found to be needed?

Hi Rob.
I have a turbine mounted on a 2.7 m length of 50mm s/steel tube. I bought some of that rubber insulation that you find on refrigeration pipes and stuffed it inside the length of the tube to dampen the resonance of the tube and it helped quite a bit. I also made some rubber mounts for the braces to the targa frame but I haven't fitted them yet.

I would also have a look at your mounting bolts as they also will transfer noise
If you have a think about neoprene car shock mount Pedders maybe
example below

It is not all about you. Have a think how the noise cruels a peacefull anchorage.

It's not all about you either. If you have a gripe, speak to the skipper who is annoying you and don't make assumptions about when and where I will running my generator.

Captainyanti, are you trying to say that wind generators are more noisy than having someone run their diesel engine in order to charge their batteries when at anchor, because I for one find that very hard to believe, there is nothing more annoying to me as sitting in the cockpit of a boat at sunset enjoying the tranquillity of the anchorage, when the peace is shattered by someone turning on their engine in order to charge their boats batteries.

Turning on a diesel motor...at sunset...to charge your battery.

Is...offensive and inconsiderate.

I mean. ..ffs....you had all day to do it

I've never had these issues so its enlightening for me to discuss it .

and I totally agree. If you have a issue....talk to the skipper.

He might not realize or in anyhow. . If he doesn't know ...how can he take action to stop?

Kinda leaves me bewildered someone would be that inconsiderate.

Maybe he was sinking and needed it for the bilges

I also detest the noise that some wind generators make. If I am in a marina and I am placed near one I complain and they either shift me or ask the people to lock the wind generator off as they actually contravene the noise rules of most marinas. People that run motors usually turn them off after a while and don't have to run them in marinas, but wind generators run all night and some inconsiderate owners leave them run in marinas, The owners may get accustomed to the sound but for others, the high pitch sound of some generators can be very annoying. So that's my bitch.
PS. There are some very quite wind generators on the market these day, so my advise is to have a good look round when buying one and actually see and hear one running in 15 to 20 knots of breeze and don't take the word of a salesman. There is a wind generator on the market that is called The Quite generator or something like that. It would have to be one of the noisiest ones on the market.

I put a wind generator on my last boat & when I was setting up my new boat I put the money towards extra solar panels - much more efficient, easier to live with & doesn't annoy anybody.

The wind gennie was just "annoying" all the time!!!

I've never had a wind generator, but I have been anchored near boats that do, and the noise they made has never bothered me as much as the deep thudding of a diesel powered engine, I recognize that I am in the minority with my opinion on this topic, with most of people having the opinion that the noise of a wind generator is like the sound of finger nails on a black board, but then that sound never bothered me either, we all have faults that annoy others, so don't be surprised if when you ask someone to do something about their wind generator noise, they turn around and ask you to do something about whatever it is that you do that annoys them.
