What is the term for the length of the ship plus the scope of chain?

Explanation:
Swing circle describes the circular area a vessel can sweep around its anchor. The radius of that circle is the sum of the ship’s length and the scope of the anchor chain out on the line. This concept matters for safe anchoring because it shows how far the vessel could move due to wind, current, and tides, so you can keep other boats and hazards outside that area. The other terms refer to direction, depth, or vessel width and don’t describe the potential movement around an anchor.
