but not all are made equal. The Honda and Yamaha ones are never going to be as quiet as the ambient noises in a quiet anchorage, but they're a lot quieter than the cheaper inverter-generator knock-offs coming out of China and sold under well-known names, such as I posted in my Amazon review... Not just the measurable volume, but the tone and lack of harmonic rattles is significantly less irritating in the Yamaha/Honda units.
