"Red, Right, Returning" tells you to leave the red markers to your right, or starboard, when returning from sea.The green markers are then left on your port side and between is the channel. Be sure to look behind you when navigating a narrow channel to make sure you are not being pushed out by wind or current.
Floating Red markers are called nuns and are cone-shaped. They are numbered with even numbers. Floating Green markers, on the other hand, are called cans and are square-shaped like a large can and carry odd numbers.
