What does a red buoy indicate when navigating?

A red buoy typically indicates the right side of a channel when returning from sea. This is based on the "buoyage system," which is a navigation system used to mark safe water routes and channels. In this system, red buoys are generally placed on the right side of a vessel's path when entering from the open sea, following the convention of keeping red to starboard.

This marking is crucial for safe navigation, as it helps boaters maintain a proper course and avoids hazards that may be present in the waterway. Understanding this navigational system is vital for ensuring maritime safety and for the effective use of navigational aids.
