Real wind data
Apparent and true wind, heading, heel, GPS position, and speed over ground with real-time updates.
Sailing hardware, built in the open
A portable sensor unit measures wind, GPS, heading, and heel, then sends live data to the screen you already carry.
Open hardware + sailing app
Real marine hardware, open firmware, and a web app—powered from USB-C and designed to be repaired.
Veetr is a portable sailing dashboard and hardware design for sailors who want useful data without buying into a closed marine electronics stack.
It combines an ESP32 controller, ultrasonic wind sensor, GPS, and 9-axis motion sensor with a Progressive Web App that runs on phones, tablets, and laptops. The current project is best suited for dinghies, daysailers, small boats, charter sailing, and backup instrumentation.
The long-term goal is a sustainable open source product. Today, the complete design is available for builders and contributors while the community grows toward a certified, distributable hardware release.
Veetr is how you pronounce “wind” in Czech.
Why Veetr
Built for sailors who value independence
Runs on your devices
The web app works on phones, tablets, and laptops, and can be installed without an app store.
No boat rewiring
Prototype hardware runs from USB-C power and is designed for boats without a permanent electrical system.
Open by default
Firmware, PCB files, app code, and documentation are available for builders and contributors.
Measurements
The sailing data Veetr is designed to show
- AWS
- Apparent wind speed
- AWA
- Apparent wind angle
- TWS
- True wind speed
- TWA
- True wind angle
- SOG
- Speed over ground
- HDG
- Magnetic heading
- Heel
- Boat tilt angle
- GPS
- Position and signal quality
App
A dashboard made for repeated use on the water
Large values, responsive layouts, offline installation, and Bluetooth connectivity keep the instrument practical on small boats. Because it is a Progressive Web App, it runs on phones, tablets, and laptops without an app store.

Fit
Where Veetr makes the most sense
Best fit
- Dinghies, daysailers, and small keelboats
- Charter boats where you want your own instruments
- Backup data independent from fixed boat electronics
- Sailors who like repairable, inspectable hardware
Less ideal
- Offshore installations needing certified equipment today
- Boats already committed to a complete proprietary stack
- Users who need a finished retail product immediately
- Installations where DIY electronics are not acceptable
Roadmap
From open prototype to sustainable product
Finished hardware is not sold yet. The current project phase is about builders, audience, feedback, and a certification fund that can make the first batch possible.
