Harken Rigtune Pro Digital Tension Gauge 2.5-5mm

About Harken’s New RigTune Pro 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. The Harken RigTune Pro was conceived and developed by Lou Varney of Diverse Yachts/Tropical Engineering. Leading the project for Harken was Andy Ash-Vie, managing director for Harken UK and Andy Reynolds-Jones, product manager. “Being a mainsail trimmer at the top end of the sport, I’ve sailed on many different race boats and I get involved a great deal with setting up and tuning the rig,” explains Lou Varney. “One of the key things I’ve learned is that the mast and rig need to be set up the same from one tack to the other. Being able to get a repeatable setting is critical to boat speed and performance. This is why there is an essential need for something more precise than feel to measure rig tension. We solved this problem with Harken’s RigTune Pro.” Unlike inaccurate spring-loaded gauges, the Harken RigTune 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. USES The Harken Rigtune Pro accurately gauges the tension of 2.5- to 5-mm rigging, including wire rope, rod, and PBO. FEATURES • The Rigtune Pro is fully precalibrated. • The gauge measures to the kilogram (SWL 500 kg) and reproduces fast settings accurately. • A large, simple digital display is easy to read and requires no guesswork. MATERIALS • Stainless steel wire guides and cam resist deformation for accurate measurements every time. • The splash-proof body of the Harken Rigtune Pro allows sailors to readjust their rigs on the water.
