Anchor Rode Size Guide
Selection Process for determining your Main Anchor Rode Set Up
1. Select your size
- Find the column in the table below that best represents your Boat Length Overall.
- Compare your displacement with the tonnage listed.
- If it is greater than displayed in your column in the table, consider moving across to the next column to increase the diameter.
- 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
N.B. This table is only a guide with columns based on:
- Top Qualty LIROS Rope
- LIROS recommendation
- Jimmy Green experience and customer feedback
- Top Quality Grade 40 Anchor Chain
Anchor Rode Size Factors:
Displacement to Length ratio i.e. is your yacht relatively light or heavy for her length?
Anticipated anchoring conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds.
Your overall assessment of the risks involved (worst case scenario).
Weight and design of your bower (main anchor) and also the specification of your secondary anchoring system.
An Anchoring System includes every part of the anchor rode from the anchor to the bitter end: anchor, chain, warp and all the individual means of joining it all together e.g. connectors; swivels; shackles; splicing.
All the individual parts need to be comparable in strength. The Anchor System is only as strong as the weakest link.
The increased holding power of modern anchors means that all the joining elements are subjected to higher loads than ever before.
2. Select from:
- All Chain - Calibrated Anchor Chain
- Rope / Chain Combination : Anchor Warps Spliced to Chain
- Rope with additional separate chain : - Anchor Warps CALIBRATED ANCHOR CHAIN
A second (kedge) anchoring system is generally recommended in addition to the full specification primary (bower) system.
The specification can vary widely according to cruising intentions - from a full specification second storm anchoring system to a traditional Kedge e.g. lunch hook or stern anchor.
Different anchors have varying degrees of holding power according to the seabed, so the option of a geometrically different anchor may be advantageous if the primary system is not holding.
Traditionally, a second anchor system has less chain, more rope and a lighter stowable anchor - making the whole system physically easier to store on board and deploy when required.
