Your boat at a glance. Even when you’re not on board.
You’re at home on the sofa, your boat is in the harbour or at anchor. One look at the app is all it takes: Where is it, how’s the battery, how’s the wind, is the anchor watch on? And if something’s off, your boat lets you know with a push notification.
- Anchor watch right on the Hub, even when your phone is off
- Battery alarm when the voltage drops below your limit
- Always up to date: live status from your boat*
What sailors experience with Smartboatia
“We have been using Smartboatia on our round-the-world sailing trip for two years and don’t want to sail without it anymore. Based on the recorded data, we make better decisions while sailing. This gives us safety and makes many things easier.”
“My favorite feature of Smartboatia is the automatic logbook: it is a real time-saver and I can see where I have been sailing at any time. Also, the remote access gives me a huge sense of security: I can see the water level, wind values and whether my boat is safely in the harbor from home, without having to go there myself.”
“The automatic logbook function is one of the best features of Smartboatia for me. I can track my voyages at any time, and the software gradually learns my boat’s characteristics. The graphical representation of wind and weather changes helps me assess conditions. I also appreciate being able to revisit my voyages later, alone or with friends.”
Your logbook writes itself.
Casting off, sailing, engine on, tacks, gybes, anchoring: the Hub detects it and logs it with time and position. It learns when your engine is running on your boat, no engine sensor needed. Add notes if you like and export your logbook as a PDF.
- Writes itself, completed by you
- Engine detection that learns
- Print-ready logbook as PDF
On board in three steps
- Step 1
Check if the Hub fits.
Tell us which connectors are behind your chart plotter. We’ll show you whether you need a cable or adapter and add it straight to your cart.
Check compatibility 
Step 2Install the Hub.
Connect it to your NMEA 2000 network, or to Raymarine SeaTalkNG or Simrad SimNet with an adapter, plus 12 or 24 volt power. The guide takes you through it step by step.
Step 3Connect the app.
Download the app, create your Smartboatia ID and join the Hub’s Wi-Fi. From there, it runs on its own and gets to know your boat better with every trip.
Older NMEA 0183 system or no network on board yet? That works too, with a translator or starter kit. The check shows you what you need.
AI that knows your boat.
Your own trips turn into polar diagrams that show what your boat really achieves in every wind. Trim recommendations help you get closer to that optimum. Manoeuvre analysis shows how many seconds you lose in a tack.
- Polars from your real sailing data
- Trim recommendations
- Tack rating and manoeuvre analysis
Your data belongs to you.
Your chart plotter stays on board, and so do your favourite apps. The Hub shares your boat data with navigation apps over Wi-Fi. With the Standard subscription you can export your tracks as GPX and your polars for other routing apps. No closed system, no lock-in.
- NMEA 2000
- SeaTalkNG & SimNet via adapter
- NMEA 0183 via translator
- Export as GPX & .pol

Follow your friends’ boats live, relive your best trips and share them as a photo or route video on Instagram, Facebook or in your sailing group.
What’s inside the Hub
Small, rugged and packed with sensors. The Hub is your boat’s brain.
- Analyses all your boat data right on the Hub, even without internet. The AI gets to know your boat better with every trip, for example when your engine is running.Onboard computerThe brain on board
- Its own position, course and speed over ground. Your backup GPS that steps in when instruments or plotter fail.GPS receiverKnows where you are
- Measures how much your boat heels and how rough the sea is.Motion sensor (IMU)Feels every move
- Measures air pressure around the clock and records the trend. If pressure drops or rises fast, the app shows an alert on board.BarometerSees weather coming
- Measures the voltage of the battery the Hub is connected to. Raises an alarm if it drops below your threshold. Also visible remotely.Voltage sensorBattery watch
- Built-in buzzer for anchor and battery alarms. Connect an external alarm for extra volume.Buzzer and alarm outputLoud wake-up call
- Sends alarms and boat status to your phone, even without internet on board. Doesn’t provide internet for your devices.Hub cellularWith a Standard subscription, wherever Hub cellular is available.Cellular module
- Your phone, tablet and nav apps connect straight to the Hub to get your boat data, even without internet. It’s a data network for your boat, not an internet connection. Your devices only get internet when the Hub itself is online, for example via marina Wi-Fi or a hotspot.Wi-Fi access pointPhone connection
- Reads your instruments directly on the bus, like wind, depth, speed, AIS and autopilot. No gateway needed. SeaTalkNG and SimNet work with an adapter.NMEA 2000 connectionLink to your onboard electronics
- Takes your navigation data from NMEA 2000 and 0183 and sends it, including AIS, via Wi-Fi to apps like OpenCPN or Aqua Map.Wi-Fi multiplexerData for your apps
Your boat measures for itself. And helps science.
Air pressure, wind and sea state: your Hub records real trends right where you are. No weather service knows your anchorage this well.
Only around 2 percent of the oceans are measured regularly, mostly along the major shipping lanes. Your Hub measures air pressure and position right where nobody else does, and Smartboatia passes this data on to the German Weather Service (DWD). Together with the SOOP network, we’re working to make even more measurements available for ocean research.
- Activate once, then it runs automatically
- Air pressure & position to the DWD
- Partners: DWD, SOOP
Built by sailors. Assembled in Travemünde.
Why do our navigation instruments only provide short-term measurements such as wind and speed data?
“We believe we can achieve much more – from optimizing boat handling to predictive maintenance.”
The idea was born in 2019 on the Pieritz family’s round-the-world voyage, and in 2021 it became Smartboatia.
