You are operating a powerboat at night You see red and white light on another boat What does this light tell you?

The red and white light on the other boat indicates that it is likely a sailing vessel under sail with an active engine, as the red light signifies the port (left) side and the white light indicates the stern. This configuration suggests that the other boat is either at anchor or maneuvering in a way that requires caution. As the operator of the powerboat, you should maintain a safe distance and be prepared to yield to the sailing vessel.
