What effect does a more vertical pull have on an anchor's holding power?

• A. Increases holding power
• B. Decreases holding power
• C. No effect
• D. Depends on anchor type

Answer: (B)

When an anchor holds, its power comes from the flukes biting into the bottom and resisting the load as it tries to drag the anchor along the seabed. A more vertical pull tends to lift the anchor rather than drive it deeper, so the flukes lose their grip and the anchor can start to pull out or drag. A more horizontal pull, by contrast, presses the flukes into the seabed and increases resistance, strengthening holding power. In some anchor designs and seabed conditions there are exceptions, but the general rule is that vertical pull reduces holding power.
