- B. 30 to 40 fathoms
- C. 70 to 100 fathoms
- D. 20 to 30 fathoms
Why A is correct
NAVEDTRA 14343 §4-2 states the common working rule of thumb is five to seven times the depth of water measured from the hawsepipe to the bottom. Five times 10 fathoms equals 50 fathoms; seven times 10 fathoms equals 70 fathoms, giving a range of 50 to 70 fathoms.
