Mooring with two bow anchors has which major advantage over anchoring with one bow anchor?

Correct Answer: Option A — The radius of the vessel's swing will be shortened.

Mooring with two bow anchors significantly restricts the vessel's swinging circle compared to a single anchor. By deploying two anchors at an angle, the vessel's movement is constrained to a smaller arc, which is essential in confined anchorages or narrow channels where excessive swinging could lead to grounding or collisions.
