I have a 26' Chaparral cuddy; it's not an obnoxious boat. When switched to "loud," for lack of a better term, it doesn't sound obnoxious or even remotely close to annoying. It has a nice rumble to it. I'm thrilled that I can now switch to quiet when coming into a marina at night or other area where people would appreciate me switching to "quiet" and not get in trouble for trying to be considerate.
I've actually gone the last few years with the system disabled because of the law. Now I am going to use it the way it was intended to be used. I will be enjoying it during the day as I have been but coming in quietly to marinas at night.
I don't understand why some people just assume the masses are reckless with poor intentions. I think there are more people like me than not.
