Buying Guide

Choose the right diameter

Match line diameter to boat size and expected loads—1/2" is common for small to mid-size craft while larger boats need thicker rope

Prefer double-braided nylon

Double-braided nylon offers high elasticity and abrasion resistance for absorbing shock from wakes and wind

Check splice and eye quality

Factory-spliced eye loops reduce chafe and failure points compared with tied eyes or heat-sealed ends

Pick appropriate length

Use longer lines for variable dock heights and tidal change—25 ft is a practical standard for many mooring setups

Look for UV and abrasion resistance

Marine-rated nylon with UV inhibitors and reinforced covers will last longer in sunlight and against dock hardware
