What must you do if you see another vessel is red and white lights off your starboard bow?

If you see another vessel displaying red and white lights off your starboard bow, it indicates that the vessel is likely a sailing vessel under power or a vessel restricted in its ability to maneuver. You should take caution and be prepared to give way, as it is on your starboard side and you are required to avoid crossing its path. Additionally, you should monitor the situation closely and be ready to maneuver as necessary to ensure safe passage.
