According to the Inland Rules, where should red buoys be passed when going upstream?

Inland navigation rules generally follow the system of “red right returning,” which directs boaters to keep red buoys on their starboard (right) side when traveling upstream toward the headwaters. This principle is part of the broader set of navigation markers used to delineate channels and ensure safe passage. When approaching a red buoy from downstream, it indicates the edge of the navigable channel; therefore, as one travels upstream, keeping the red buoy on the right ensures that the vessel remains within safe waters and avoids grounding or hitting obstacles.

This alignment not only helps in maintaining a safe course but also aligns with the established convention for buoy color-coding, which aids in navigation by providing consistent guidance to mariners.
