USCG Exam PracticeAnchoring — types, scope, holding ground
Your vessel is anchored in 8 meters of water with a bow height of 2 meters above the waterline. Conditions are calm with good holding ground. According to the Boatswain's Manual, what is the minimum recommended rode length?
- A. 56 meters
- ✓ 70 metersCorrect
- C. 80 meters
- D. 100 meters
Why B is correct
Scope is calculated as the ratio of rode length to water depth plus bow height. Total depth reference is 8 + 2 = 10 meters. The Boatswain's Manual §2.2 recommends 7:1 scope in calm conditions with good holding ground, giving 7 × 10 = 70 meters of rode.
