You are operating a powerboat at night you see red and white lights on another but what does these lights tell you?

If you see red and white lights on another powerboat at night, it indicates that the vessel is likely underway and operating. The red light typically represents the port (left) side of the boat, while the white light is the masthead light, showing that the boat is moving in your direction. In this case, you should maintain a safe distance and be prepared to take action to avoid a collision.
