A solar powered wind measurement instrument
OpenWind measures: AWA / AWS, compass and pitch / roll. In addition to that, our application calculates COG, SOG, VMG, AWD, TWA, TWD and TWS.
Signal range
OpenWind uses Bluetooth 4.2, which has a maximum range of 50 meters when the signal is unobstructed. The Bluetooth antenna is oriented downward from the device, yielding better range if mounted higher on the vessel. Older smartphone models and hard cases will reduce the effective connectivity range.
Broadcast signal
Only one device can connect to the OpenWind instrument at a time. This connected device will be able to send data back and calibrate the sensors. However, multiple devices can simultaneously read the broadcast signal.
With the OpenWind broadcast signal, you and your crew will be able to read wind data on a smartphone, tablet, smartwatch, and NMEAkit™ simultaneously.
Depending on the device, broadcast reading may not be possible, and Bluetooth connectivity range may also be affected. We recommend using recent models of smartphones, tablets, and smartwatches.

UDP from third party Apps
Many sailing applications offer a way to communicate with wind instruments. Via UDP, you can read the data from OpenWind as NMEA0183 wind sentences in third-party applications such as iSailor, iRegatta, NKE, and OpenCPN.
Any application that can read NMEA0183 wind sentences data via UDP is compatible with OpenWind.
NMEAkit™ device
NMEAString™ mast rotation compensation
The NMEAString is a mechanical solution designed to compensate the wind direction on boats equipped with a rotating mast.
Attached to the mast, the string is pulled in or released as the mast rotates, allowing it to calculate the rotation angle.
The NMEAString™ can be calibrated with the NMEAkit application (available on iOS and Android). Up to three angles can be set, such as -90°, 0°, and 90°.
The NMEAString™ works either with the OpenWind™ device or as a standalone unit.

Polar diagram
The polar diagram illustrates a sailboat’s potential speed across various wind speeds and angles. These diagrams are valuable tools for training new sailors, offering a visual representation of how different sail trims and courses impact boat speed. In racing, knowing the boat’s performance at various points of sail allows for strategic course planning. Sailors can decide the best tack or gybe to optimize their route around the racecourse.
Take advantage of the new polar diagram function in our application to determine your optimum boat speed and use this information to plan your routes effectively.
Smartwatch compatible
You can find the OpenWind application for Smartwatch in the iOS AppStore, Google play store, Samsung Galaxy Store and Garmin Connect IQ Store
Display compatibility
OpenWind is compatible with SAILMON and NOVASAIL display. It connects directly via Bluetooth between the display and the instrument. No cables are required.

One device. Multiple applications.
Pair with a multifunctional application that measures wind speed, wind direction as well as pitch & roll and heading information.
OpenWind App
It is the OpenWind main Application with a more complex interface. It displays AWS, AWA, AWD, COG, SOG, VMG, TWS, TWA, TWS, pitch, roll, compass, bluetooth and battery information. It includes a map with OpenSea Map Overlay and can also compensate mast rotation. This application can run in the background and send the wind data via UPD in NMEA0183 sentences to third party applications.
WindLogger App
For iOS only, the WindLogger app can read the data via UDP from the OpenWind App in the background. It can do average data readings from the last 30, 60 or 120 minutes from AWS, TWS and SOG. It also gives you maximum readings from TWS, AWS and SOG. It is possible to export the logged data in CSV format (AWA, AWS, TWA, TWS, COG, SOG, Yaw, Pitch, Roll).
NMEAkit App
The NMEAkit application allows you to calibrate the mast° position and activate mast rotation compensation. It also allows calibration of the wind direction, pitch and roll from the OpenWind device. The application displays if the NMEAkit is connected or reading broadcast signal from OpenWind. It also displays AWA, AWS, pitch, roll and yaw readings from the OpenWind device.
WindTrainer App
The WindTrainer App connects directly to OpenWind via Bluetooth, it does not require the OpenWind App to be running in the Background. This app plots the magnetic wind direction and wind speed to a graph. It is a simplified version of the WindLogger app, designed for trainers and race officers.
MacOs App
Requires macOS 11 or later and a Mac with the Apple M1 chip. This application allows you to connect your OpenWind device directly to your Mac! Send OpenWind data via UDP to third party applications such as OpenCPN.
