We Purchased an Air Breeze from E-Marine in 2009-based on its reputation for lower noise and high amp output compared to other wind generators.
We replaced the original black blades after 6 years this summer with the beautiful blue carbon ones.
The significant reduction in blade/generator noise was apparent to us all Summer.The Black Blades were especially noisy in oscillating wind conditions-The Blue Blades are very quiet in all wind conditions-and exhibit a beautiful shimmering reflection in the sun -
The wind generator with the blade upgrade also seems to spin and deliver more amps at lower wind speeds.
The Extra cost was worth the expense -
Incidentally we purchased our 1987 41.1 Bristol Aft cabin version in 2006 and immediately added E marine Solar panels -We have never had to run the Westerbeke while at anchor for 7 days-our longest stay in any one place while cruising for 6 weeks each summer --Thanks E-marine for this and your great advice and customer support.
