Fuzzy logic FLL. A boat capable of going 45 without a high performance motor will sound a lot louder then a boat with a high performance motor going 60. The 45 mph boat is turning 4000 rpm while the 60 mph boat is turning 3000 rpm. Less rpm means less noise. Also both boats has to run at the same decibel or less because of the decibel law.
So what's your drift????
