Official USCG Answer & Rule Citation

Correct Answer: Option B — 12.6 fathoms

One fathom is defined as exactly 6 feet, and one meter is approximately 3.28084 feet. Converting 23 meters to feet yields 75.459 feet. Dividing 75.459 feet by 6 feet per fathom results in approximately 12.576 fathoms, which rounds to 12.6 fathoms for standard navigational chart calculations.
