The bassboat world speed record is 116.594 MPH: I suspect it wasn't "quiet". Every boat is quieter at slow speeds.
I can understand the bassboaters' gripe, though. Mostly, they are speeding equidistant from the shores: Even in fog
, when there's no other craft on the water—certainly no sailboats.
That said, there could be an exemption for bass tournaments as there already is for "legal" speedboat races.
(But not for "illegal" races, as this eagle-eyed boater witnessed):
