What do red and green markers indicate?

Red and green markers are used in navigation to indicate the sides of a channel. The mnemonic "red right returning" helps boaters remember that when approaching from the sea, red markers should be on the right side. This system is part of the IALA buoyage system that aids in safe navigation by clearly defining the route for vessels. Green markers signify the left side of the channel when returning, while red markers signify the right side, ensuring that boaters can safely enter or navigate through channels without running aground or encountering hazards. Understanding this system is crucial for safe boating practices, particularly in unfamiliar waters.
