"I travel a lot in my job, and it is especially nice to be able to check the app for how my boat is doing. I’m checking it around 3 times a week to look at water levels, battery power and movement."

Smart monitoring to improve your boatlife

The SmartBoat One system continuously sends data from your boat to the app, meaning you’ll always have current and historical data for each sensor system.



You will be notified if the house or starter battery drops to critically low power levels. The system supports both 12V and 24V.


Water level

SmartBoat One measures the water level in the bilge and sends an alert when the water level is too high.



The unit has an integrated accelerometer that shows G-force. Be sure that your boat isn’t getting too roughed up in the waves.



One temperature sensor measures water temperature in the bilge, the other measures the air temperature in the engine room.


Bilge pump

SmartBoat One monitors bilge pump activity. In the graph you will get a clear overview when the bilge pump is switched on and how long it runs each time.


GPS position

The integrated GPS antenna will give you real-time information about your boat's position using all available satellites in the area.
