Anchor and stern lights are not the same thing.
yep. dumb idea. but I'm not the guy running the boat.That's probably one of the dumbest things people do at night in a boat. Anytime you are not anchored you are considered under way and must have all proper nav lights turned on. I have witnessed quite a few accidents first hand where "floaters" felt they only needed an anchor light on or felt it was better to turn all lights off in order to have a better view. Stupid if you ask me.
Red-Right-Returning. Meaning if you are approaching a red light to your right you are entering a port, harbor or another vessel is approaching you. But O.D 1 said it best, Lighted R.R Cups!
