What does Rule 26 govern about the actions taken by a vessel when at anchor?

Rule 26 of the COLREGs indeed governs the actions of vessels when at anchor and specifically focuses on the requirement for these vessels to display proper lights. When a vessel is at anchor, it must show specific anchor lights to ensure its presence is recognized by other vessels, particularly during nighttime or reduced visibility conditions. The visibility of these lights is crucial for maintaining safety at sea, as it communicates to approaching vessels that the anchored vessel is not underway, which helps to prevent collisions.

Proper navigation lights are essential as they enhance visibility and awareness among all vessels operating in the vicinity. The requirement to display anchor lights is part of the measures to mitigate risks associated with maritime navigation and promotes adherence to safe practices while at anchor.
