We have an Air Breeze, installed by the previous owner on our Maramu. Mounted on a SS pole at the stern on the port side. Right above the aft cabin. I have to disable it at night due to vibration and a low moan/hum. Its spins very quiet but the hum is way loud. I have fussed and fussed to try and eliminate the moan/hum but its worse than having an obnoxious poltergeist. If I had a shotgun, the wind gen would probably die violently.
We have used solar panels on prior boats. When I have the time and $$ I will install panels on the Maramu.
Bill and Andrew are correct. Panels are a way better solution. I would not myself buy and install a wind-gen until I had invested in as many panels as I could conveniently mount. With the panels be sure to get a top quality charge controller.
