Nothing ruins a peaceful morning on the hook in a quite anchorage like the sound of someone's generator. We heat water in a teapot on the propane stove and pour it through a Malita filter into a cup or thermos.
An elitist's - Whaaaa!
I recommend ear plugs if any boater does not want to hear the general goings on that make-up the boating world. 30 to 45 minutes of a well tuned, clean running, well muffled, considerably quite genset at 9 ish in the morn - or for that matter 6 ish in the eve - anchored well separated, is (should be) no real problem to others. There are many situations that call for low decibel human actuated sounds to occur throughout the day in the boating world... most for the purpose of elevating family enjoyments.
