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.

You are approaching the starboard side of another vessel
During nighttime transit another boat's lights show: Green - the right, or starboard side, of that vessel; Red - the left, or port side, of that vessel; White - the rear of that vessel. The vessel is heading directly toward you
If you see another vessel's red and white lights off your starboard bow, it indicates that the other vessel is crossing from your right side. You should maintain your course and speed, as the other vessel is likely the stand-on vessel. However, be prepared to take action if necessary, ensuring you can safely avoid a collision. It's also important to monitor their movement and assess the situation continuously.
If you see another vessel's red and white lights off your starboard bow, it indicates that the other vessel is likely approaching from your port side. You should maintain your course and speed, as the other vessel is the give-way vessel. However, remain vigilant and prepared to take evasive action if necessary. Always ensure you are following the rules of the road for navigation to avoid collisions.
You should take early and substantial action to steer well clear of the other craft.
If you see another vessel's red and white lights off your starboard bow, it indicates that the other vessel is approaching from your port side (left side) and is likely a power-driven vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGs), you should maintain your course and speed while being prepared to take action if necessary. It's essential to keep a proper lookout and assess the situation to avoid any potential collision.
If you see another vessel's red and white lights off your starboard side, it indicates that the other vessel is a power-driven boat underway and is either crossing your path or overtaking you. You should maintain your course and speed, as the other vessel is likely to give way. However, keep a close watch on their movements to ensure safe navigation. If there is any doubt about their intentions, be prepared to take evasive action if necessary.
In darkness or reduced visibility, the white light indicates a vessel's stern, while red and green lights indicate the port (left) and starboard (right) sides, respectively. A vessel displaying a red light is facing another vessel, while a green light indicates it is on the starboard side. This color coding helps mariners determine the direction and type of vessel they are encountering, ensuring safe navigation.
