The Yamaha EF2000is is very quiet. At full load it's definitely noticeable,
but we can still converse in a normal voice at 3 meters. Ours rarely runs at full load. A 700-watt microwave and a 5K btu air conditioner are our biggest loads. Our normal load in the summer consists of lights, television, 20-amp battery charger
, the air conditioner, and some incidental loads. With this load the generator
is no where near full power and the noise
level is very tolerable. The microwave and the AC unit starting up will rev the generator
all the way up, but only for a few moments. Rowing away from the boat on a calm night, I can't hear the generator at about 10 meters when it's running at about half load. YMMV, but we're very happy with ours.
