Dock Line Configuration
Proper dock line setup is essential for safe berthing:
- Bow Line: Primary forward securing point with spring action
- Stern Line: Primary aft securing point preventing drift
- Spring Lines: Control fore/aft movement during tidal changes
- Breast Lines: Prevent lateral movement away from quay/pontoon
UK Tidal Considerations: Spring lines essential in high tidal range areas - prevents damage during rising/falling tides.

Dock Line Sizing Guide for UK Waters
Correct dock line sizing is critical for safe mooring in tidal UK waters:
| Boat Length | Recommended Diameter | Typical Length Required | UK Tidal Considerations |
|---|---|---|---|
| Up to 8m (26ft) | 10-12mm | 1.5x boat length minimum | Add 50% length for high tidal range areas |
| 8-12m (26-40ft) | 12-14mm | 1.5x boat length minimum | Consider 16mm for exposed locations |
| 12-15m (40-50ft) | 16-18mm | 2x boat length recommended | Heavy duty cleats essential for larger diameter |
| Over 15m (50ft+) | 20mm+ | 2x boat length minimum | Professional mooring design recommended |
Important: These are minimum recommendations. Exposed berths, high winds, or extreme tides may require heavier specifications. Contact our marine experts for site-specific advice.
