Question 4087Deck General70% to pass

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

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.
