Check Lines


Check lines are temporary lines used to check the fairness and symmetry of a ship's hull during construction or repair. They are attached to predetermined points on the hull and pulled taut to ensure that the hull is properly aligned and shaped according to the design specifications. Check lines are typically made of strong, non-stretching material such as wire or synthetic rope, and are adjusted using turnbuckles or other tensioning devices. The use of check lines is an important step in ensuring that a ship's hull is structurally sound and able to perform optimally in the water.
