What is the best guide for determining the proper scope of anchor chain to use for anchoring in normal conditions?

Correct Answer: Option B — One shot of chain for every fifteen feet of water

One shot of chain (15 fathoms or 90 feet) for every 15 feet of water depth is a standard rule of thumb for deep-water anchoring. This ratio ensures sufficient catenary to maintain the anchor's horizontal pull, which is essential for maximizing the holding power of the ground tackle.
