ABSTRACT:
A sailboat rigging fatigue indicating terminal assembly is provided for receiving and retaining the end of a tensioned metal rigging rod or the like subject to fatigue caused by vibration. It comprises a fitting having a securing portion at one end and an internal bore extending from its other end surrounding and securing the rod. At its outer rod receiving end, the fitting has a fatigue indicating portion defined by a weakened area, which may comprise an annular groove, spaced inwardly from the end of the fitting, which, upon breakage at the weakened area, releases the fatigue indicating portion to indicate decreased rod fatigue life.
