USCG Exam PracticeAnchoring and mooring operations
When anchoring in storm conditions, the USCG Boatswain Manual recommends a scope ratio of:
- A. 5:1
- B. 7:1
- ✓ 10:1Correct
- D. 15:1
Why C is correct
USCG Boatswain Manual Ch. 2 §2.2 states scope should be 7:1 in good holding ground and calm conditions, increased to 10:1 in storm conditions. Less scope reduces holding power because the rode must rest along the bottom for the anchor to set.
