What should a vessel do if it is approaching a boat displaying a red light?

When a vessel is approaching another boat that is displaying a red light, it indicates that the other boat is either a power-driven vessel that is constrained by its ability to maneuver or possibly a boat that is restricted in its ability to move due to its circumstances. This situation represents a navigation hazard where the vessel must take action to avoid a potential collision.

Changing direction to avoid collision is the correct response because it prioritizes safety on the water. By altering course, the vessel can navigate safely past the other boat displaying the red light, thereby reducing the risk of an accident. In areas where visibility and maneuvarability may be compromised, this precaution is crucial in ensuring the safety of all vessels involved.

Maintaining course and speed or signaling the other boat does not adequately address the potential danger posed by the red light and could lead to a collision. Accelerating to pass may further shorten the distance to the other vessel, increasing the risk. The proper action in this situation is to actively change direction to ensure a safe passage.
