Nautical Term: Turnbuckle

Definition of Turnbuckle

A turnbuckle is a mechanical device commonly employed in maritime applications, particularly with ropes or chains. The essential function of a turnbuckle is to adjust and take up any slack in the connected cable or chain. This is accomplished through the rotation of the turnbuckle around its threaded axis.

For instance, consider a ship’s rigging, which includes a multitude of ropes and stays that support the sails. When adjusting the tension of these ropes, the sailors may use turnbuckles to take up any slack and secure the proper tension. By rotating the turnbuckle, the sailors can adjust the tension in the rope, allowing the ship to efficiently and effectively sail through the water.
