Preferred channel markers are buoys showing red and green bands.
marks the junction of two channels
A boat should cruise between a green and red buoy. The red buoy will always be located on the right side of your boat. Red buoys will always mean , returning, red, and right. There will be a number on a red buoy that will give the chart location. The numbers will always be even.
Red Right Returning- so the green buoy should be on your left side, the red on your right, and you in the middle.
Do not pass between the buoy and the shore
A can buoy is a floating cylindrical object in the water. They are red in British waters and green or black in US waters.
Red and Green Colors and/or Lights: These are placed at the junction of two channels to indicate the preferred (primary) channel when a channel splits. If green is on top, the preferred channel is to the right. If red is on top, the preferred channel is to the left. These also are sometimes referred to as "junction buoys."
a red light, of course!
If it's "red right returning", it's green left returning and green right (starboard) going. That is to say, you pass it to the left (port) as you return to port.
These are called preferred channel markers. Which means you can pass on either side, however whatever color the topmost color is is the preferred passing side. Topmost Green prefer to pass on Starboard (right) Topmost Red prefer to past on Port (left). There are sometimes lit, sometimes lettered, never numbered.

A red cone shaped buoy, called a nun buoy, usually marks the right side of the channel when you are returning from the sea or going upstream. Remember it by saying, red, right, returning.
