What is the phrase seafarers use to remind themselves of the correct course between red and green buoys when returning to harbor?

Seafarers use the phrase "Red Right Return" to help them remember the proper navigation between red and green buoys when they are returning to harbor. This phrase indicates that when returning to port, the red buoys should be kept on the right side (starboard) of the vessel, while the green buoys should be on the left (port) side. This system is designed to prevent confusion and ensure safety as mariners navigate into harbor or through channels.

Understanding this mnemonic is vital for maintaining safe passage in navigable waters, particularly in areas where channels may be narrow or crowded. This concept directly ties back to maritime navigation rules, which are critical for the safety of all vessels and individuals on the water. The other options do not pertain to the essential navigation principles of buoy systems and do not provide guidance for safe practices while returning to harbor.
