Self-Powered Autonomous Monitoring
The Sense4Boat app gives you instant access to everything you need to know about your boat — whether you’re onboard or miles away.
Track maintenance work, monitor your anchor position, check real-time weather insights, and remotely manage your boat through connected Sense4Boat sensors. Even without sensors installed, the app offers valuable tools to simplify boat ownership.
You can organize maintenance tasks, connect directly with partner marinas, and even save on boat insurance.
Captain’s Dashboard.
Your boat’s key vitals, all in one place.
An intuitive dashboard displays sensor readings in real time, helping you quickly determine whether your boat needs attention — and confirming if your marina has already been notified of any issues.
Battery Voltage & Temperature.
Know exactly when to charge your boat’s batteries and monitor the charging process remotely.
Gain insights into charging frequency and duration, current and historical voltage levels, and temperature behavior during charging — ensuring your batteries stay healthy and reliable.
Water Ingress.
Our bilge sensor has one job: to monitor the water level wherever it’s placed.
Through the Sense4Boat app, you can easily configure alarm thresholds and choose who should be notified in the event of high water detection — so you’re always aware, even when you’re away.
Temperature.
Our heat sensor is purpose-built for the harsh conditions of engine rooms.
Using the app, you can set your preferred temperature thresholds and alert types. If there’s a sudden rise in temperature or readings exceed your set limits, you’ll receive immediate notifications via the app, as well as automated phone calls and SMS alerts.
Boat Location.
Whether you’re using the Sense4Boat GPS Locator to monitor your boat or its tender, the app makes it easy to stay informed about their whereabouts.
Set up safe zones and receive instant alerts whenever your boat enters or leaves them.
You can also view your boat’s location history, displayed clearly on a map, for any time period you select.
Activity Log.
There’s always something to fix or plan, right?
Log and categorize every repair, upgrade, or maintenance task in the Activity Log to keep a complete record of your boat’s upkeep. Add descriptions, photos, expected and actual costs, and even schedule reminders for future tasks.
Want to ignore how much you’ve spent? There’s a button for that too — we get it.

Access professional-grade nautical weather data directly in the app.
Stay informed and safe while sailing or docked, with detailed forecasts for wind speed and gusts, wave height, sea currents, rainfall, thunderstorms, and weather alerts.
