Spinlock is expanding its Rig-Sense series with the Rig-Sense Pro - a digital load measuring device for rod and wire shrouds. The instrument measures tensile loads of up to 8,000 decanewtons and has been specially developed for professional riggers and mast builders.
The Rig-Sense Pro was developed at the request of Selden Mast and is aimed at a professional range of users: riggers, mast builders and shipyards. Unlike the original Rig-Sense model, which Spinlock already has in its programme for dinghies and keel yachts up to around 30 feet, the new Pro model enables the precise measurement, documentation and certification of loads on the standing rigging of larger cruising yachts. The measurements can be recorded via the Rig Sense app and integrated into professional reports - ideal for maintenance logs and insurance certificates.
Digital display and simple operation
The device shows the measured values on a digital display. Two hands are required to attach the device, which weighs around 2.5 kilograms. The Rig-Sense Pro then clamps securely onto the wire so that both hands are free to adjust rigging screws. The measuring range covers wire from five to 20 millimetres in diameter and rodriggs from Dash 6 to Dash 60, which corresponds to diameters of five to 16 millimetres.
Documentation for professionals
The Rig Sense app for iOS and Android records the measurement data and saves it for later reference. The logged values can be used to create reports documenting the condition of the rig. The system provides traceable reference values for the correct rig tension, especially when commissioning a new mast or at regular maintenance intervals. The price also makes it clear that the Rig-Sense Pro is primarily intended for professional riggers. The measuring device costs 5135 euros. Further information at Spinlock.

Test & Technology editor
Hauke Schmidt was born in Hanau, Hesse, in 1974, but moved to the coast at the age of an Opti and grew up sailing dinghies and tall ships. School and semester breaks were used for extensive Baltic Sea cruises. During and after his oceanography studies in Kiel, he took part in various international research trips to tropical and polar regions. The focus was on ocean currents and their influence on climate change. Eventually he was drawn back to his home coast and to YACHT. He completed a traineeship there and has been working as an editor in the Test & Technology department since 2009. His core tasks include equipment and boat testing, as well as practical topics relating to electronics, seamanship and refits. As a passionate DIY enthusiast, he loves to spend his summers on the water with his family and winters working on his boat
