Anchor Warps

Anchor Warps can be subdivided into 3 main types by application: Main or Bower, Secondary and Kedge. The main anchor rode system may be all chain or a chain/rope combination but a long length of suitable anchoring rope with a short piece of chain for the anchor end is much more convenient to store and deploy for additional warps that are not stowed for’d in the chain locker.

The secondary anchor rode should be comparable in strength to the bower if it is considered a genuine cruising back up.

Kedge covers a multitude of different uses including lunching, kedging, club hauling and anything that involves deployment via the dinghy. Kedge warps can be one or two sizes down in diameter from your main warp.

Similar Anchoring Rope properties are required for Anchor Snubbers, Mooring Strops, Mooring Bridles, Towing Warps, Para Anchor and Yacht Drogue Bridles and Warps.

The main requirements for all these applications are good strength without being over-sized and difficult to handle and good shock absorption.

Nylon is generally the solution because it is stronger and has more elongation (elasticity, stretch) than polyester. Nylon has 20% stretch at the breaking point, whereas polyester has 15%. However, polyester has excellent all-round properties which may hold sway. Additional snubbing methods can then be employed when required.

The main decision to make is between a 3 Strand twisted construction or an 8 (Octo) Plait construction such as Anchorplait.

The quality of the splicing is very important to the integrity of the rode.

The next decision to make is whether you want the warp and chain as a continuous spliced entity or as two separate connectable parts.

  1. Splice a heart shaped thimble (nylon, galvanised or stainless steel) into the anchor end of the warp and connect to a short length of chain with a suitable rated shackle.
  2. Splice the rope directly onto the chain – For these options go to: Anchor Warps Spliced to Chain

The custom build design of our rope products allows you to select the appropriate splice for the anchor end and also a suitable finish for the bitter end if required. You can also add anti chafe options.

Jimmy Green Marine offer a choice of 4 different LIROS ropes for Anchor Warps.

Selection Process for your Main Anchor Warp:

1. Select the appropriate sizing for your yacht:

  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 your yacht is a multihull, consider moving across to the next column to increase the diameter.
  4. Consider the worst case scenario for your anticipated Anchoring - this will dictate whether you go for the minimum required or the 'belt and braces' approach
