What is the total length measured in feet for 15 fathoms of anchor chain?

• A. 75 ft
• B. 90 ft
• C. 120 ft
• D. 150 ft

Answer: (B)

To determine the total length of 15 fathoms of anchor chain in feet, it's essential to know the conversion factor between fathoms and feet. One fathom is equal to 6 feet. Therefore, to find the total length, you multiply the number of fathoms by the number of feet in one fathom.

Calculating this gives:

15 fathoms * 6 feet per fathom = 90 feet.

This calculation confirms that the accurate length for 15 fathoms of anchor chain is indeed 90 feet, making this choice correct. Understanding this conversion is crucial in navigation and seamanship, as it allows for accurate measurements and clear communication concerning depths and lengths in nautical contexts.
