Deck General · Anchoring
Increasing the scope of anchor cable improves holding power chiefly because it:
- AReduces the vertical angle of pull at the anchor, keeping the pull horizontal✓ Correct
- BIncreases the weight resting on deck
- CShortens the catenary
- DLifts the flukes clear of the bottom
Explanation
A long scope keeps the pull on the anchor nearly horizontal so the flukes stay buried. A short scope raises the angle and tends to break the anchor out. Typical scope is 5:1 to 7:1.
