When dragging of an anchor occurs, you must back it up with a piggyback (backing) anchor or _______________.
AI Explanation
The correct answer is B) reposition it at a greater range.
When anchor dragging occurs, the best course of action is to reposition the anchor at a greater range from the vessel. This allows the anchor to dig in more securely and reduces the chances of further dragging. Backing up the anchor with a piggyback (or secondary) anchor is an additional measure that can be taken, but repositioning the primary anchor at a greater range is the first recommended step.
The other options are not the best solutions for anchor dragging. Reducing the riser tension (A) may not address the root cause of the dragging. Changing the winch (C) or the anchor heading (D) would not directly resolve the dragging issue. Repositioning the anchor at a greater range is the most effective way to regain a secure anchor hold.
