Fibre rigging is increasingly popular for multihull standing rigging and specific yacht rigging applications.
Fibre is relatively untested for high load shrouds and stays, so for applications with this degree of rigging strain, we recommend taking advice from the rope manufacturer or an onsite qualified rigger/surveyor. Consider the specification very carefully before switching from Stainless Steel Wire to Fibre for Standing Rigging
The main benefits of composite, synthetic fibre rigging relate to a significant reduction in weight, a considerable increase in strength and the benefits of positive visual inspection.
The diameter of dyneema fibre rigging should be specified by two critical criteria:
As a consequence, when fibre rigging is specified to ensure zero creep at the expected load, it will be far stronger than the wire it replaces. Correctly stipulated fibre rigging should result in at least a doubled break load and it could be even as great as x5 The extra strength is a reassuring factor because it allows for a certain amount of chafe and UV damage during use without compromising the rig.
The advantage of fibre rigging and their fittings is not only a reduction in weight, but also the opportunity for a full visual inspection. Any sign of wear, or deterioration will be gradual and visible which allows for an appropriate maintenance schedule to avoid any risk of failure. The first signs are best described as a fuzziness on the exposed surface of the fibres. The crucial factor is that deterioration occurs on the outside which is in stark contrast to stainless steel wire where failures can occur from within without any advance warning.
Specifying fibre rigging is a process that should relate directly to the comparative stretch characteristics of the wire it is replacing.
Fibre rigging should not be specified by breaking strain alone as this will inevitably result in a stretchy rig.
