Mooring Line Arrangements - Infographics

A typical mooring arrangement uses six main lines to keep the vessel safely alongside the berth:

1. Stern Line – Prevents the vessel from moving astern.
2. Aft Breast Line – Holds the stern section alongside the quay.
3. Aft Spring Line – Controls the vessel’s forward movement.
4. Forward Spring Line – Controls the vessel’s aft movement.
5. Forward Breast Line – Keeps the forward section alongside the berth.
6. Head Line – Prevents the vessel from moving ahead.

Key point: The combination of head/stern lines, breast lines, and spring lines controls the vessel’s longitudinal and lateral movements, providing a stable and safe mooring arrangement against wind, current, waves, and passing-vessel effects.
