Abstract: A method and apparatus for monitoring and measuring the load in a sailboat's rigging components. A rigging component such as a turnbuckle is modified to incorporate a sensing element, such as a strain gage. Strain gages are bonded and wired into a measuring circuit. The strain gage measures the strain under a load and generates an electrical signal that is directly proportional to the tension load. The load is then monitored and/or displayed using standard data acquisition equipment. The strain gage also identifies loose rigging such as may happen with shrouds which are subject to sudden high loading with movement of the boat and allows the operator to tighten that shroud or other piece of rigging.
