Question 4012 Deck General

The correct answer is D) 72 feet (21.9 meters). According to the standard scope of anchor cable, which is typically 6 to 8 times the depth of the water, for 12 feet (3.7 meters) of water, the recommended anchor cable length is 72 feet (21.9 meters) (6 x 12 feet = 72 feet). The other options are incorrect because they do not follow the standard scope of anchor cable for the given water depth. Option A (2 feet) is too short, Option B (18 feet) is too short, and Option C (48 feet) is also too short for the 12 feet (3.7 meters) of water depth.
