Boat GPS tracker
A boat tracking device is only useful if it tells you something when it matters. Cloud Shelter reads the position from your boat's own GPS through the NMEA 2000 gateway, shows it live in the portal, and — when the boat is armed — alerts you the moment it moves or the engine starts.
Every passage is logged automatically with its route, distance, engine hours and fuel, so the tracker doubles as your boat's logbook.
Arm the boat from the portal or from Telegram when you leave. If the engine starts, if the boat makes way, or if it drifts away from where you left it — even slowly, even with the engine off — you get an immediate alert. A boat being towed away silently is exactly the case a speed-only tracker misses.
The boat's position, speed, course and heading update in the portal while the boat is online, with the place named — your berth, a known anchorage or the nearest harbour — rather than raw coordinates.
Departures, arrivals and anchorages are detected from the track. Each passage records its route, distance, time under way, engine hours and fuel used, ready to annotate with crew and notes.
Arm the anchor watch and the same position feed watches your swing circle, sounding the siren aboard and alerting your phone if the boat drags.
A movement alert arrives on Telegram and names the boat, what happened — engine started, making way, or drifted from where it was secured — and how far it has moved, with a button to acknowledge it. The position and track are on the boat's page in the portal, so you can see at once whether it is a mooring that has slipped or a boat being taken.
When you disarm the boat because you are aboard, open movement and engine alerts clear on their own.
While the boat is online, the gateway reports roughly every fifteen seconds. If the connection drops, readings are buffered aboard and the track fills in when it reconnects, so the logbook is complete even after a passage out of signal.
Your boat's data is hosted in the EU, in Frankfurt, and stays in your account. You can export it or delete the account at any time from your settings.
Every boat on an account has its own live position, passages and alerts. The fleet board shows where each boat is and which one needs attention first — useful for charter operators and for owners who keep more than one boat.
What it needs: a GPS on the boat's NMEA 2000 network (most chartplotters provide one) read by the Cloud Shelter gateway, or a Victron Cerbo GX, plus an internet connection aboard. It is not a standalone battery-powered tracker to hide on board.
No. It uses the boat's own GPS through the NMEA 2000 gateway, powered by the boat. Its strength is alerting you while the boat is armed — engine start, movement or drift — rather than hiding aboard.
Yes. Drifting beyond about 100 metres from where it was armed raises an alert even at zero speed, so a silent tow is caught.
It needs a GPS position on the NMEA 2000 network. Most chartplotters and many instruments provide one.
Yes. Several boats can sit on one account, each with its own live position and passages.
It is the position from the boat's own GPS on the NMEA 2000 network — the same fix your chartplotter shows.
About every fifteen seconds while the boat is online. Offline, readings are buffered aboard and the track fills in when it reconnects.
