Aires install questions...

I'm starting to plan out this install. I see that my wind generator down tube will prevent a perfect centering of the Aires mount tubes. Would it hurt the performance to have it 3 inches to port? I might be able to move the w/g tower a bit port but would rather not. Not familiar with this vane, and can't find this addressed online.

Re: Aires install questions...

I would not hesitate to move our Aires over 3". I would think the kind transom you have would be one factor. An old narrow type like ours would limit the move to not much more than that.

Re: Aires install questions...

IMHO keep the windvane center, move the tube.

I have seen hydrovanes and windpilots pacific offset, but all I have read on pendulum wanes was to keep them in the center line.

Okay, just spoke with Guy from aireswindvaneusa. He told me to keep it centered midline. He also advised me the servo rudder should be positioned with 1 inch above waterline at rest.
Thanks for the comments....

Re: Aires install questions...

Also agree with keeping the windvane centerline. It is Much harder to set it properly if it is offset!

Re: Aires install questions...

This photo is from the official Aries website Aries
It is difficult to be precise, but it seems rather more than 3 inches off center.

The site has been redesigned since I last visited it (some years ago) I was sure there used to be something about off-center mounting being acceptable.

Obviously, the boat will behave differently on a different tack, a combination of less servo pendulum in the water on one tack, and maybe a different airflow over the vane. However, 3 inches doesn't sound a great deal. It equates to 1.4 inches higher or lower than centerline mounting when heeled at 25.

I think centerline mounting is best, but if you need to go 3 inches off, then it is no big deal (IMHO)
