Editing Standing rigging (section)

== Materials ==
On modern yachts, standing rigging is often stainless [[steel]] [[wire rope|wire]], [[Nitronic|Nitronic-50]] stainless steel rod or [[synthetic fiber]]. Semi-rigid stainless steel wire is by far the most common as it combines extreme strength, relative ease of assembling and rigging with reliability. Unlike rigid stainless steel rod, it is comparatively easy to recognize wear and stress as individual strands (normally 19) break often near a [[Swaging#Pipes and cables|swage fitting]], and can be inspected while standing.<ref name = Skipper>

This process requires a different, expensive machine but yields a more durable end fitting. Rod-type stays fail suddenly (rather than strand by strand as a cable would), often where the rod bends around a [[Spreader (sailboat)|spreader]]. Bending can induce unseen stress fractures.<ref name = Hood>
