70% to pass

Using a scope of five, determine how many feet of chain you should put out to anchor in 12 fathoms of water _______________.

A 60 feet (18 meters)
B 450 feet (137 meters)
C 360 feet (110 meters)
D 72 feet (22 meters)
AI Explanation

The correct answer is C) 360 feet (110 meters). To determine the amount of chain to put out when anchoring, the general rule is to use a scope of 5 times the depth of the water. In this case, the water depth is 12 fathoms, which is equivalent to 72 feet (12 fathoms x 6 feet per fathom = 72 feet). Multiplying the water depth of 72 feet by a scope of 5 gives us the correct amount of chain to put out, which is 360 feet. The other options are incorrect because: A) 60 feet is too short for a 12 fathom water depth with a 5:1 scope. B) 450 feet is too much chain for this depth. D) 72 feet is only the water depth, not the amount of chain to put out.
