USCG Exam PracticeAnchoring and mooring operations
An anchor holds best when the pull on the shank is horizontal. Which factor most directly achieves this condition?
- A. Using a stockless anchor rather than a Danforth anchor
- B. Anchoring in firm mud or clay rather than sand
- ✓ Veering sufficient scope so the catenary keeps the shank parallel to the bottomCorrect
- D. Passing the chain stopper before the vessel falls back on the anchor
Why C is correct
The catenary — the sag of the heavy chain — keeps the pull on the anchor shank horizontal when adequate scope is veered. A short scope lifts the shank and can break the anchor out. Bottom type affects holding power but does not directly control the angle of pull.
