HullSense monitors the systems that matter most — battery, bilge, location, and weather — and puts it all in your pocket.
HullSense uses a 16-bit ADS1115 ADC to measure your battery voltage with precision that cheap voltage monitors can't match. Set your battery chemistry once and the app calculates an accurate state of charge every time.
A Hall-effect current sensor clamps around your bilge pump wire and detects every activation without cutting or splicing anything. You know the moment your bilge runs — and how long it ran.
The built-in GPS module gives you your boat's exact position. Whether you're at the marina or checking in from across the country, you always know where your boat is.
Local conditions matter on the water. HullSense pulls a 7-day forecast and NOAA tide predictions for your marina automatically — no setup, no API keys, always free.
You don't have to be watching the app for HullSense to keep you informed. Critical events trigger an instant push notification to your phone wherever you are.
A Hologram eUICC SIM card is built directly into every HullSense device. Subscribe to Pro and it activates automatically — no trips to a carrier store, no plan to manage.
See how your battery has behaved over time and track every bilge activation in detail. Patterns that are invisible in the moment become obvious when you can see the full picture.
Draw a zone around your marina, mooring, or storage facility on the map. If your boat moves outside it, you get an instant alert — whether it drifted, dragged anchor, or something worse.
Knowing your battery voltage is one thing. Knowing whether your battery is actually healthy is another. HullSense analyzes resting voltage patterns over time to estimate condition and remaining useful life.
