What is the best guide for determining the proper scope of anchor chain to use for anchoring in normal conditions?
AI Explanation
The correct answer is B) One shot of chain for every fifteen feet of water.
This is the recommended scope of anchor chain to use in normal conditions according to the U.S. Coast Guard regulations. The general rule is to use approximately 7-10 times the depth of water as the scope of anchor chain. This ensures the anchor has sufficient holding power to keep the vessel securely in place. Using one shot (90 feet) of chain for every 15 feet of water depth falls within this recommended range.
The other options are incorrect because they do not align with the standard scope recommendations. Using less chain (options C and D) would not provide adequate holding power, while using more chain (option A) may be excessive in normal conditions and could lead to unnecessary tangles or issues with retrieval.
