When encountering a powerboat in darkness or reduced visibility what do visible white and red lights indicate?

In darkness or reduced visibility, a powerboat displaying a white light indicates that it is underway and likely moving, while red lights typically signify that the boat is at anchor or restricted in its ability to maneuver. A red light may also indicate the presence of a fishing vessel with gear in the water. When approaching, it's important to understand these signals to determine the boat's status and navigate safely. Always adhere to navigation rules to avoid collisions.
