The holding power of an anchor at a given scope of cable increases when the _______________.
AI Explanation
The correct answer is B) the amount of chain lying along the bottom increases.
The holding power of an anchor is directly related to the amount of chain or cable lying on the seafloor. As the amount of chain increases, it creates more surface area and friction with the bottom, which improves the anchor's ability to hold the vessel in place. This is a key principle in anchor design and deployment.
The other options are incorrect because: A) increasing mooring line tension does not affect the anchor's holding power, C) reducing the catenary length (the curved part of the chain) decreases holding power, and D) decreasing the amount of chain on the bottom would reduce the anchor's grip on the seafloor.
