Bottom line : I would not trade my noisy Air-X ...
First, one does not have to put up with the noise of an Air-X, which one disgruntled owner described as "a device that converts wind power into noise with a little electrical power as a by product!" I have a KISS, it produces much more power than an Air-X, and very little noise. It is simple, robust, and can be switched off electrically. There are a number of other units on the market that also produce more power, with less noise than an Air-X.
I know of a number of Airmarine/ Air-X owners who have returned there units, due to unreliability and excessive noise. I avoid anchoring near any yacht with a Air-X, as the noise is objectionable even to others anchored nearby!
Do a bit of research on the web, and you will find a unit to suit your boat.
