Deck General · Mooring Lines
Which mooring line runs forward from the bow at an angle toward the dock and primarily prevents the vessel from moving aft?
- AAfter breast line
- BBow spring line (forward spring)✓ Correct
- CStern line
- DForward bow line
Explanation
The bow (forward) spring line leads from the bow aft to a dock fitting amidships or aft, running at an acute angle to the vessel's centerline. It prevents the vessel from surging aft. A stern (after) spring line runs from the stern forward along the dock to prevent surging ahead. Breast lines are perpendicular to the vessel and prevent lateral movement away from the dock.
