Without getting into the quiet Vs noisy brands of generator
, regarding their noise
above decks, there is "transmitted noise" that is heard ONLY down below. It can be NO PROBLEM or be VERY loud.
If your pole is on the transom & the struts go down to the cockpit's caprail... AND if you have sealed off lazeretts under the seats rather than a quarter berth or aft cabin
, you should have no problem with transmitted noise
IF the struts come down to the cabin
top, or any other part of the cabin that is inhabited, you have a problem. You can help a bit with extensively rubber mounted pole and struts, but noise may still drive you up a wall.
This was exactly the case for us. Our AmpAir, (the quietest unit ever made), was VERY quiet below on my previous boat, because it was scenario #1 above. Years of building later, I mounted it on our current
boat, which was scenario #2 above. It almost drove us MAD!
That was when I swapped it out for another large solar
panel on a stern rack. WHEW! what a relief!
