With the SailTimer Wind Vane, you can use the beautiful display on your smartphone or tablet, and don't need to spend extra money on an additional single-purpose LCD screen (that is going to sit in storage during the off-season).

Because the SailTimer Wind Vane is wireless, there are no wires to install down the mast or through the cabin walls and under the cockpit to the helm. That also means less weight, and less noise in the mast than with a standard anemometer.

This is the only marine anemometer that can send wind data through the air to your smartphone or tablet. It uses wifi for iPad, iPhone or iPod, and Bluetooth for Android.

If you have real-time wind data being sent from the SailTimer Wind Vane, it lets you get amazing tacking results in the SailTimer app.

  • Display a graph of wind and boat speeds for the day.
  • Show both True and Apparent wind speed and direction.
  • Generate polar plots for your individual boat.

As the wind changes, your tacking results update in the app automatically.

Get the SailTimer Wind Vane for sailing this summer.




  • Wireless: no wires to install down the mast adding noise and weight.
  • Solar-powered renewable energy; can run day & night indefinitely.
  • The first wind cups designed for sailboats; the innovative blade shape maintains equal accuracy when sailing heeled over (unlike standard cup, ultrasonic and propeller anemometers).
  • Submersible.
  • Advanced features, low price.
  • The first masthead anemometer with a digital compass built right in the wind direction arrow.
  • That means you even get wind direction while docked or swinging at anchor, when GPS heading is not available.
  • With new features in app updates on iOS & Android, the Wind Instrument actually becomes more useful over time.
  • 5th-generation includes silent, maintenance-free AirGap Axle™. It monitors solar charging and power consumption so that you can check the exact battery level at any time. Send air temperature to an app or online map.
  • The first masthead anemometer that works with rotating masts.
  • Simple set-up: calibration to the bow of your boat is not required.
  • Provides a visual indicator of wind direction and wind angle, better than ultrasonic sensors that have no wind direction arrow.
  • For sailboats of all sizes, from keelboats to centreboard sailing dinghies and even small multihulls (no 12-volt battery required).
  • Small vertical design rather than the common horizontal structure, to deter large seabirds.
  • Masthead mount or portable with an L-bracket for walls/posts and adapter for 1/4" tripod / Gorillapod / GoPro mount.
  • Wide temperature range from tropical heat down to -40 degrees (C/F).
  • Designed to work with third-party apps and hardware using the industry-standard NMEA 0183 format.
  • Wind direction equally sensitive all the way around; no dead band at the end of the rotation as in wind direction sensors with potentiometers.
  • Transmits every second.
  • The first-ever masthead anemometer with crowdsourcing of live wind maps.
  • Even if your boat is already in the water, you can raise the Wind Instrument without having to lower or climb the mast. Another first!



SAILTIMER AIR LINK™ - Accessory for plugging in to on-board wired marine electronics

This small waterproof device connects wired marine electronics, mobile apps and the cloud.  For input, this is the only device that can receive Bluetooth transmissions from the SailTimer Wind Instrument™ and connect on wires to your GPS chartplotter or autopilot.  For output, it is also the only device that can connect your wired anemometer to the crowdsourced wind and race maps at SailTimerMaps.com.

The Air Link is easy to use, but can do a lot of things...

  • It can receive Bluetooth 4 wireless data from the SailTimer Wind Instrument™.
  • It lets you display the wireless wind data in NMEA 0183 format on wired marine electronics (or even a Raspberry Pi device), live wind maps online, and with wifi to a web browser or to apps. 
  • The Air Link can also can take input from a wired anemometer for viewing on live wind maps at SailTimerMaps.com.  If there is internet in your marina, you can then check wind conditions on your old wired anemometer from home or office.  That has never been possible before. 
  • It can also retransmit all of your NMEA 0183 data on wifi, connecting your wired network to the advanced features available in mobile apps




The SailTimer API™ receives the encrypted Bluetooth LE transmissions from your Wind Instrument. It does some conversions and calculations with the data coming in, hands the wind data to another app for viewing, then runs quietly in the background.

There are two purposes for the API. (1) We did the computer programming , so that each different app using the Wind Instrument would not have to. (2) The Wind Instrument is opening the door to new features for sailboat navigation that have never been possible, like crowd-sourcing of real-time wind maps. The API gives you the option to share your wind data with others in live wind maps.

Live wind maps are better than weather forecasts or GRIB simulations made hours or days ago far from where you are sailing. You would never actually set your sail positions and tacks based on a weather forecast. But what if you could see what the wind is like right now, from Wind Instruments on boats up ahead? Rather than just relying on your own anemometer, you could adjust your tacking route using crowd-sourced wind maps to show where the winds are most favourable. That has never been possible before. The SailTimer Wind Instrument™ is a connected device, and is setting new standards. It is the first masthead anemometer to provide crowd-sourcing of wind data for live wind maps. (This is optional with the Share button in the API, with good control of privacy and security - FAQ.)

ANDROID: For Android, in the Play store you can download the free SailTimer API™ to receive the wireless data. Version 2 connects quickly across most Android devices.

IOS: For iOS, the free API is in iTunes at https://itunes.apple.com/us/app/sailtimer-api/id959558893?mt=8. It connects to the Wind Instrument quickly and automatically.

There is a short demo of how to use the SailTimer API™ with your Wind Instrument on YouTube. It is made with the iOS API, but the basic principles also apply to the Android API.

Once you get the API you can register to log in, or you can register at SailTimerMaps.com.

Once you have the API, Other Apps lists chartplotter and performance apps that can connect to the API to display data transmitted from your Wind Instrument.
