smarttune is an innovative solution for accurate, live measurement of forestay load. Simple for crews to retro-fit at the dock, smarttune makes repeatable headsail shape control available for yachts of all sizes, at all levels. With precision-designed, highly-accurate wireless technology, smarttune truly is a plug-in performance upgrade for your boat.


PLUG & PLAY INSTALLATION - smarttune fittings are a simple, screw-in replacement for existing turn screws. Wireless connectivity means no need for drilling holes to run cables from the sensor, and the receiver plugs directly into your existing instrument package.

WIRELESS TECHNOLOGY - Live forestay load data is sent wirelessly to your onboard instrumentation, or direct to your smartphone via App (Android and iOS), for the ultimate in convenience.

DESIGNED FOR THE ELEMENTS - smarttune Sensors are IP67 rated. The precision-machined plastic bodies are designed and built to withstand the rigours of the foredeck.

HIGH ACCURACY LOAD SENSOR - Precision engineered for accuracy, smarttune directly measures the actual forestay load – no more worries about alignment errors.

FACTORY CALIBRATED - smarttune fittings go through a rigorous calibration procedure before being shipped, saving you from time-consuming calibration and providing accuracy “out of the box”.

PRECISION DESIGN - smarttune fittings are created with the latest FEA computer design tools and built with state-of-the-art 3D manufacturing processes.
