Harken Rigtune Pro
Digital Rig Tension Gauge

As stiffer hulls and low-stretch rigging provide a more reproducible and measurable environment, this innovative product helps sailors measure and fine-tune rigging with far greater accuracy.

Unlike inaccurate spring-loaded gauges, the Harken Rig Tune Pro measures rig tension to the nearest kilogram. As rigging is deflected over three pins on the back of the gauge, a load cell records the pressure on one of the pins. The measurement is displayed on a simple, easy-to-read screen. The RigTune Pro accommodates a specific range of rigging sizes (2.5-5mm), reducing the need for multiple gauges and eliminating conversion tables.

The gauge measures to the kilogram (SWL 500 kg) and reproduces fast settings accurately
