A solar powered wind instrument

OpenWind measures: AWA / AWS, compass and pitch / roll. In addition to that, our application calculates COG, SOG, VMG, AWD, TWA, TWD and TWS.

Real time Data

Access to a wide range of wind and navigation metrics and enhance your sailing experience. Using your phone’s built-in GPS, the app calculates true wind speed and direction, boat speed, course over ground, and other navigation metrics for precise sailing performance.

Calculations

VMG = SOG * cos(TWA)

TWS = sqrt(SOG * SOG + AWS * AWS – (2 * SOG * AWS * cos(AWA * 3.14/180)))

TWA = acos((AWS * cos(AWA * 3.14/180) – SOG) / TWS) * 180 / 3.14

AWD = AWA + Heading

TWD =   TWA + Heading 

in-built Battery

OpenWind is designed to maximize battery life by avoiding full discharges. Its oversized solar panel and low energy consumption help extend longevity. The 1200 mAh battery typically draws -8 mA when connected with no sunlight, 0–30 mA on partly cloudy days, -7–0 mA on overcast days, and charges up to +80 mA in full sun. When not connected, the device enters sleep mode, disabling noncritical functions

wind Blades

OpenWind is designed for sailors to provide accurate wind speed and direction measurements, using advanced algorithms that account for boat drift and current. Its uniquely designed anemometer blades, licensed from SailTimer Inc., maintain precision even when the boat is heeling, improving on traditional half-sphere cup anemometers. 

Mounting OpenWind

 

OpenWind includes a rail mount that is can be attached to the most common rails found on sailboats. The aluminum mounting bracket which is attached to the OpenWind unit can be adjusted 360 degrees on the rail mount.
Another alternative is to fasten the device directly to the mast, or to any other part of the boat. Please note that the bluetooth signal propagates better with less obstruction and from a higher mounting position.
If there is no flat surface on the top of the mast, we offer a mast mount that enables you to mount it in a vertical position.

Mast mounting   

 

To mount on the vertical side of the mast, we offer a mast mount that can be fixed with 4 rivets.

If you have a flat surface on the mast, you can screw the upper part of the rail mount on in, or you can screw the aluminum or carbon extender directly on the flat surface. You will only need 2 holes for M3 screws with 15 mm distance between them.
