Using a scope of 6, determine how many feet of anchor cable you should put out to anchor in 12 feet (3.7 meters) of water.

Correct Answer: Option D — 72 feet (21.9 meters)

Scope is defined as the ratio of the length of cable paid out to the depth of water. With a depth of 12 feet and a scope of 6, the calculation is 12 feet multiplied by 6, resulting in 72 feet of anchor cable required for proper holding.
