What should you do if you see a red light at night on another vessel?

Seeing a red light on another vessel at night indicates that the vessel is facing towards you on its port (left) side. According to navigation rules, this means you are required to give way to that vessel.

By giving way to the right, you are following the proper maritime conventions to avoid a collision. This response ensures safety on the water and adheres to the "rules of the road" that dictate how vessels should interact with one another in various situations. It also highlights the importance of understanding light signals and their meanings while navigating at night.

Other responses, such as speeding up or continuing on your current path, would likely lead to risky maneuvers that could result in collisions. Moreover, changing course to avoid another vessel should not be done arbitrarily, as it requires careful consideration to ensure that any new path taken does not interfere with the movements of other vessels.
