What action is required of a Powerboat when approaching the starboard side of a Sailboat in darkness or reduced visibility?

When a powerboat is approaching the starboard side of a sailboat in darkness or reduced visibility, it must maintain a safe distance and be prepared to take evasive action if necessary. According to navigation rules, the powerboat is considered the give-way vessel, meaning it should avoid interfering with the sailboat's course. The powerboat should also ensure that its navigation lights are clearly visible to indicate its presence to the sailboat.
