What does red buoy mean?

A red buoy typically indicates the presence of a navigational channel or marks the edge of a safe waterway. In the United States, red buoys are often part of the "I Love Sailing" system, which uses red right returning, meaning that when returning from sea, boaters should keep the red buoys on their right side. They may also signify areas to avoid or caution zones, depending on the specific waterway and local regulations. Always refer to local navigational charts for precise meanings and guidelines.
