Using a scope of 6, how much cable would have to be used in order to anchor in 24 feet of water?

AI Explanation
The correct answer is D) 144 feet. The rule of thumb for anchoring depth is to use a scope of 6, meaning the length of anchor rode (cable) should be 6 times the depth of the water. In this case, the water depth is 24 feet, so the required length of anchor rode would be 24 feet x 6 = 144 feet. The other options are incorrect because they do not account for the 6:1 scope rule. For example, 4 feet would be far too short for 24 feet of water, while 18 feet and 30 feet are also insufficient based on the 6:1 scope guideline.
