Every now and then something very cool and helpful comes along to help take some of the guesswork out of our sailing. Enter Cyclops Marine’s Smarttune turnscrew and Smartlink load sensors. Smarttune sensors are used exclusively for standing rigging applications, but the Smartlink sensor can be used just about anywhere. What’s especially cool is that you can see the data they provide in real time, and you can download all of it to a smart phone to view it on a graph or in other formats. While these sensors might not be race legal in your class (they’re not in the J/70), they are immensely useful for training. I used them on the J/70 Midlife Crisis in preparation for the 2021 World Championships in Los Angeles, California.
To display the sensor information on our J/70, we used a B&G Triton2 display, which requires the addition of Cyclops’ wireless gateway to the NMEA2000 backbone of the B&G instruments. The data is compatible with many other instrument brands and can also be viewed using the Cyclops Marine “Smart Fittings Manager” App, communicating via Bluetooth. The App allows you to review, record, graph, and save the data in multiple formats. The graphing function is especially revealing as it shows what’s happening with the rig tension, etc. as you go through settings on the dock or sailing upwind through different conditions…
