Single Leg Mooring Tail
FBR Single-Leg Mooring Tails are synthetic rope extensions that add elasticity and absorb energy in combination mooring systems. Available in nylon (polyamide), polyester, or polyester–polyolefin mixed fibers, each tail has a single rope body with a spliced eye at each end. Protective eye covers help reduce abrasion at connection points.
Used with low-stretch HMPE or steel wire main lines, these tails help moderate peak loads caused by vessel movement at ports and terminals. Standard finished lengths of 11 m and 22 m, together with specified eye dimensions, allow the tail configuration to match the mooring arrangement. They are suitable for ship-to-shore mooring, including exposed berths where additional elasticity is needed to manage dynamic loads.

Single Leg vs. Grommet Mooring Tail
| CHARACTERISTICS | SINGLE LEG | GROMMET |
|---|---|---|
| Construction | Single-leg | Grommet / endless loop |
| Compliance | Higher | Lower |
| Stiffness | Lower | Higher |
| Elongation | Higher | Lower |
| Typical Selection | General-purpose applications | Higher-strength or specific system requirements |
| Key Consideration | Energy absorption | Strength, stiffness and system configuration |
*The relative comparison assumes the same rope material, construction, constituent-rope diameter, effective loaded length, and applied load. Final selection should use the specified strength and load–extension data for each assembly.
Selecting a Mooring Tail
An 11 m tail is a common configuration. For the same rope construction and loading conditions, a 22 m tail provides more available extension and may be selected for exposed berths. Tail length should balance dynamic load reduction with the vessel’s allowable movement and the overall mooring arrangement.
Select material and diameter using the required Tail Design Break Force (TDBF), wet-condition performance, and load–extension characteristics. When replacing a tail, match the specified stiffness and elongation response as well as its strength.
Eye dimensions, connection hardware, and chafe protection should be selected together to suit the main line and connection geometry.
