Ridoir in practice
A turnbuckle joins the bottom of each stay or shroud to its chainplate. Turning the threaded body draws the two ends together to tighten the wire, or apart to loosen it.
Once set, turnbuckles are locked with split pins or locking nuts so they cannot unwind with vibration. Tape over the pins to protect sails and hands.
Common questions
- What is a rigging screw?
- The same thing: rigging screw and bottle screw are British names for a turnbuckle.
- How tight should rigging be?
- It depends on the boat. Many rig tension guides suggest around 15 to 20% of the wire's breaking load, measured with a tension gauge.
