You are operating a pleasure craft at night. You see red green and white lights on another boat. What do these lights tell you?

The red and green lights indicate that the other boat is a sailing vessel, with the red light on the port (left) side and the green light on the starboard (right) side. The presence of a white light suggests it is either a power-driven vessel or a sailing vessel under certain circumstances. The combination of these lights means you should assess your course to avoid a collision, as their orientation indicates the other vessel's direction and status. Always prioritize safe navigation and adhere to the rules of the road.
