Jimmy Green 3 Strand Nylon Anchor Chain Snubbing Strops absorb the shock loading associated with all-chain anchor rode systems - a single stretchy nylon line transferring the strain from the chain to a suitable deck strongpoint - avoiding the windlass and moderating the jarring jolts caused by the sea state.
The snubbing line can be led offset through a port or starboard fairlead, but for longer-term anchoring, it should pass over the bow roller, through the stemhead fitting and attach to the most suitably positioned strongpoint.
This will require a careful, precautionary appraisal of any potential wear points and preventive action where necessary: Anti-Chafe Options
Jimmy Green Chain Snubbing Strops are available in Anchorplait, Eight-Strand and traditional Three-Strand construction.

LIROS Three-Strand Nylon Article 00110 Facts, Features and Plus Factors:
- Thermofixed twisted lay construction 100% high tenacity Nylon (Polyamide)
- Manufactured to DIN EN ISO 1140
- Spliceable to chain
- Dependable strength
- Excellent durability
- UV and abrasion resistant
- Excellent shock absorbing elasticity >20% working load stretch
LIROS Break Load:
LIROS Three-Strand Nylon has the same strength and stretch properties as the Anchorplait/Octoplait Eight-Strand version.
Three-Srand Rope is less expensive than Anchorplait, but the twisted lay shrinks as it dries after water immersion, potentially resulting in a stiff, cumbersome line after time, especially in the larger diameters.
Overall, LIROS Three-Strand Nylon is a very strong and stretchy mooring warp that represents exceptionally good value when used for permanent or semi-permanent mooring but is not usually recommended for frequently adjusted and stowed mooring warps where Polyester may be a more suitable fibre.
Jimmy Green Three-Strand Single Line Snubbing Strops - Facts and Features:
- A Jimmy Green snubbing line should be approximately 3 metres to 10 metres in length - the longer it is, the more it will stretch
- The line can be attached to the chain with a rolling hitch or a spliced chain Hook/Grab/Gripper, which can be retentive - the other end is made off to a strongpoint on the foredeck
- It is possible to extend the length of the snubbing line by careful routing (avoiding chafe points) to a strongpoint further aft
- N.B. Chain hooks are not designed to fit through the link of a calibrated chain. Locate the chain hook, gripper, or grab over one link so that the load is bearing on the outside of the next link (which will be at right angles).
- The strength (diameter) of the strop should be comparable with your main anchor rode
- Splicing retains far more of the original rope strength than tying a knot - knots can reduce the break load by as much as 50%, while a professional splice will generally retain approximately 80-85% of the original load capacity (this percentage may vary with the rope and splice construction)
- Adding a mooring compensator will increase the elasticity of the strop - this extra shock absorbing capacity could be utilised to reduce the length of the line.
- Adding anti-chafe webbing will protect the line where it leads over the bow roller, through the stem fitting and where it may come into any abrasive contact from there to the strongpoint
Jimmy Green Advisory
Attaching the hook or grab with a shackle may seem a little clunky, but it does mean that the hook can be removed for a mooring application and replaced if required.
