What do you mean "two day average"? It produced 38Ah in 48 hours?

That sounds about right -- that's 38Ah at 12 volts; I'm at 24 volts. I'm getting about one Ah per hour, so more than double what the 913 produced, which is logical since I'm in double (approximately) the wind.

Net-net -- it's very little power.

Google Rutland 913 Practical Sailor...

Re: Wind Generator

Dockhead, I have used the Ampair 100 for the last 15 years and have found its usefulness to be marginal at best. It averages 25 amp hours on a normal day and needs 15-25 mph to create more hours. It is quiet, dependable and relatively maintenance free but for the installation required, solar panels would probably be a better option. However, the new German built Superwind 350 has received excellent reviews and consistently produces high output of amp in lesser winds. There is an excellent discussion at the following site. Hope you find this helpful. - Canada

DH, your problem is as we discussed, is were to put them without ending up with scaffolding all over the stern. Perhaps the answer is semi-flexible panels flat somewhere on the stern decks. Barden have them all be it a little expensive. My SM160 came from them.

Re: Wind Generator

Just put in an Air Breeze and it is working great, easy to mount without an expert. Just read the instructions. Keeps my batteries charged and between that and a small panel, it covers all of my needs. Now, we do have winds here but it starts to generate power in light winds. I my first choice was a D-400, but 2,000 + price tag said no. I also wanted an internal regulator which the Air Breeze has. The new blades are quiet, wife has no problem with it. Got stuck for 6 days with no power at Christmas in Martinique, overcast, so added wind power to my boat. $1000 well spent, would do it again.
