I am going to side with Roger on this very touchy issue. Its just not the pwc and big boats. Yes they can be annoying to someone fishing.
My issues are on boat driver safety, judgement, control, and fundementals of boat driving. Doesnt matter what kind of boat you are in just use some curtousey and common sense. A big scarab running next to a 20' bass boat by a dock is going to get swamped and push the boat up on the dock. been there done that too many times. A boat going south and a little left heading towards a boat going north a little to the right doesnt turn left in front of the guy heading south a little to the left he turns right instead of cutting in front of him.
Some of the lakes around here like kinkaid or Lake of the ozarks have speed limits permenant or during night on them.
