USCG Exam PracticeAnchoring and mooring operations
The USCG Boatswain's Manual specifies an anchor scope ratio of 10:1 under which condition?
- A. Good holding ground with calm conditions
- ✓ Storm conditionsCorrect
- C. When using two anchors in a running moor
- D. When anchoring in firm mud or clay
Why B is correct
The USCG Boatswain's Manual specifies 7:1 scope in good holding ground and calm conditions, and 10:1 in storm conditions. Less scope reduces holding power because the rode must rest along the bottom for the anchor to set.
