When we were cruising, we anchored far away from other boats for peace, quiet and privacy.
I did not want any crap from a sea ray....
I set up the gen-set, on my Cal 46, for no noise....double motor mounts to kill any vibration, 2 mufflers -1 water lift and 1 regular and oversized water outlet at water level, next to the AC outlet to stop the 'gurgle'....
The only way someone off the boat would know it was running was to dink near the water outlet.
I had to have 110v or the family would not go cruising....
I don't understand why someone who has 'enuf money to buy a big Sea Ray wouldn't demand a quiet generator.
Some of the gen-sets in RV's are amazing not a decible....
If someone had a noisy generator, I would grab my kids and dink over to ask what the schedule was for the gen noise.
Kids need sleep....
Sometimes it worked, sometimes it didn't.
