LIROS 3 Strand Nylon Mooring Strops

LIROS 3 Strand Nylon is an excellent solution for mooring where a yacht is unable to swing through a complete circle.

Custom build your strop online to a specific finished length with a thimble eye or loop spliced into each end.

Mooring Strop Size Guide for a Single or Double Point Mooring Configuration (Permanent Anchor Mooring)

  • Single Point generally means a Swinging Mooring - Jimmy Green Advisory - Use Anchorplait Nylon for Swing Moorings
  • Double Point could be e.g. Fore and Aft between piles

Follow the Jimmy Green selection process to estimate the optimum rope diameter for your mooring:

  1. Find the column in the table below that best represents your Boat Length Overall.
  2. Compare your displacement with the tonnage listed.
  3. If the displacement is greater than displayed in your column in the table, or the yacht is a multihull, consider moving across to the next column to increase the diameter.
  4. Take advice on local conditions and check the benchmark size from the table below against other similar sized boats moored in your area.
  5. Have a good look at the mooring configurations on neighbouring yachts with a critical eye and judge whether your set up should be the same.
  6. Consider whether you can make any improvements in terms of mooring convenience and anti chafe measures.

Yacht Length Overall < 5 metres 5 - 6 metres 6 - 8 metres 8 - 10 metres 10 - 12 metres 12 - 14 metres 14 - 16 metres
Aproximate length in feet < 16 feet 16- 20 feet 20 - 26 feet 26 - 33 feet 33 - 40 feet 40 - 46 feet 46 - 53 feet
Displacement in Tonnes 0.6 tonnes 1 tonnes 2.5 tonnes 5 tonnes 9 tonnes 13 tonnes 16 tonnes
Strop Diameter 14mm 16mm 18mmm 20mm 24mm 28mm 32mm

Use the charts above as a benchmark and consider whether local conditions dictate a diameter upgrade for your individual yacht and berthing arrangement.

N.B. Deploying more lines can reduce the total loading on each warp or act as security back up.

LIROS 3 Strand Nylon has the same strength and stretch properties as LIROS Octoplait Nylon 01058 but is less expensive. However, nylon shrinks when immersed in water causing the twisted lay to tighten, especially in larger diameters. Overall, this line makes a very strong and stretchy mooring warp that represents exceptionally good value when used for semi-permanent mooring lines. It is not usually recommended for frequently adjusted and stowed mooring warps due to the stiffening of the line over its lifetime.

Do not use as a single strop on a swinging mooring as the swing may untwist the lay of the rope (cockling) Rope Cockling
