Benefits of correct rigging tension.

The rigging tension has an important influence on both the durability and performance of the system. Contrary to popular thought a slack rig is more punishing to the cables, fittings, and hull than a properly adjusted tight rig, since it can subject the entire system to excessive movement and can cause misalignment, wear, shock loading, and fatigue. Similarly, the sailing performance is affected since the rigging tension determines the shape and deflection of the mast and the sag of the forestay. The expert skipper will benefit by maintaining consistent rigging tension while developing the optimum sail shape and sailing tactics.

Specific tension requirements for your application must be obtained from boat manufacturer, mast manufacturer, sail manufacturer or manufacturer of applicable product on which the cable or rod is used.
