Installing tandem anchors on the same mooring line is referred to as _______________.
AI Explanation
The correct answer is A) piggybacking.
Piggybacking refers to the practice of installing two anchors on the same mooring line, with one anchor being the primary and the other acting as a backup or secondary anchor. This setup provides additional holding power and redundancy in case the primary anchor fails or does not hold. It is a common practice for larger vessels or in areas with strong currents or adverse weather conditions.
The other options are incorrect because:
B) Doubling refers to using two separate mooring lines, not a single line with two anchors.
C) Paralleling refers to running two separate mooring lines side by side, not using a single line with two anchors.
D) Pre-tensioning refers to the process of applying tension to a mooring line before securing it, not the use of two anchors on a single line.
