For an anchored boat less than 100 meters, how many 360 white lights are required?

Explanation:
When a vessel is at anchor, other ships must be able to see it clearly from any direction, so rules require a white light visible all around the horizon. Two 360-degree white lights are needed to mark the vessel’s presence from both ends—one placed toward the bow and one toward the stern—so approaching vessels can determine the anchored vessel’s location and length regardless of where they come from. This setup is required even for vessels under 100 meters, and the lights should be shown from sunset to sunrise (and in restricted visibility) to ensure ongoing visibility.
