Which factor most affects whether to increase scope beyond calm-sea guidelines?

• A. Wind speed and sea state
• B. Color of water
• C. Time of day
• D. Type of anchor

Answer: (A)

The key factor is wind speed and sea state because they determine the forces acting on the vessel and, in turn, how much holding power the anchor needs. When winds and waves are light, the forces are small and the baseline scope is usually enough. As wind increases or seas roughen, you pay out more chain to increase scope, which lowers the pull on the anchor and helps it set more securely. The color of the water or time of day don’t influence anchor holding, and while anchor type can affect how well something holds in a given bottom, the decision to increase scope in response to conditions is driven by wind and sea state.
