ok first time going into the disco marina today with my son in my jetboat. and i was rolling a little faster than 5 mph but not by much seeing how it was hotter than you know what and i get a message over a loud speaker about the no wake zone. the guy has a sign on his dock that says something about 5 mph means 5 mph. i was in a 19ft jetboat and not pushing that much water. is this guy hid in his house all the time?
