Boat intelligence, in your hands
Boat intelligence is readings turned into answers. A sensor can tell you the bilge pump ran or the battery reads 12.6 volts. It cannot tell you whether that is normal for your boat, whether it is getting worse, or what you should do about it. That is the part Cloud Shelter adds.
It watches the boat around the clock, learns what normal looks like for that boat, and when something drifts away from normal it tells you what changed and why it matters, on your phone, wherever you are.
Every boat is different: one bilge pump runs twice a day by design, another should never run at all. Fixed thresholds either alarm all the time or miss the slow problem. Cloud Shelter builds a baseline for each boat from its own readings, then flags the drift away from it: what changed, by how much, and why it matters.
Engine health works the same way. On every passage it records the engine's cruise figures, coolant temperature, oil pressure and alternator output at working revs, and notes on the logbook entry when a passage runs hotter or lower than your engine's own baseline.
The battery monitor reads LiFePO4 packs over Bluetooth, several packs wired in parallel as one bank, and up to ten Victron devices, among them shunts, solar chargers and DC-DC chargers. From the bank's charge and its recent draw it projects the night ahead, so you are warned before the bank runs flat, not after.
Solar yield is rolled up day by day and compared with the week before. If shore power drops, you get an alert that the boat is now on its batteries, and a DC-DC charger that does not charge while the engine runs is flagged too.
How the boat battery monitor works
A bilge alarm tells you there is water. Cloud Shelter counts and times every bilge-pump run, so a pump that cycles more often than usual shows up as a trend: a slow leak caught early, with time to act. Two high-water floats and wireless leak sensors cover the places water should never be.
On boats whose engines report fuel rate on the NMEA 2000 bus, every passage gets its fuel burned and litres per nautical mile, and the portal finds the revs where your boat runs most economically. A low-fuel alert comes before the tank becomes a problem.
Position comes from the boat's own NMEA GPS, not a phone or a tablet that has to stay aboard and awake. At anchor, Anchor Watch draws a circle around the anchor itself once you enter the chain out. Armed, it alerts you the moment the boat moves off her position, whether she dragged, broke free or was taken.
Wind direction is worked out from the boat itself: at anchor a boat lies head to wind, so its compass heading shows where the wind comes from, and the watch alarms when it backs or veers onto a new quarter. Wind speed comes from the boat's wind instrument when one is fitted.
Certified photoelectric smoke alarms and temperature sensors in the engine room and cabins, with humidity watched for the slow damp that ruins upholstery and electronics. Smoke and temperature only: it does not detect carbon monoxide, and nothing here prevents a fire. It tells you early.
Weather and navigation warnings for the boat's area sit next to the onboard alerts, so a gale warning and a battery that is losing ground are read together, not in two different apps.
Alerts go to Telegram on your phone, wherever you are, and a siren sounds on board when one is fitted. Each alert says what happened and what it means, and you can silence or acknowledge it from the phone.
Yacht monitoring with Cloud Shelter
A logbook that writes itself from the boat's track, with engine hours, fuel and conditions; a maintenance schedule by date and engine hours; service history, spare parts and the vessel's documents, all attached to the boat.
Each signal on its own is a reading. Together, the boat's normal, the drift from it, its position, the wind, the battery outlook and the bilge trend, they become answers about your boat. That combination is what we mean by boat intelligence, in your hands.
What it needs: the Cloud Shelter devices that match what you want watched (the battery monitor, the Lookout hub with its wireless sensors, the NMEA 2000 gateway) and an internet connection aboard, marina Wi-Fi, 4G or Starlink. The hub and gateway are wired to the boat's power; the sensors are wireless. Engine, fuel and wind figures need instruments that report them on the NMEA 2000 bus.
Readings turned into answers. Instead of only showing a number, Cloud Shelter learns what is normal for your boat and tells you when something drifts away from it, what changed and why it matters.
No. Thresholds are part of it, but the core is a baseline per boat: a pump that runs more than usual, an engine running hotter than its own cruise figures, a battery bank that will not last the night.
Yes. The intelligence runs in the Cloud Shelter portal, so the boat needs marina Wi-Fi, 4G or Starlink for readings and alerts to reach you. The siren aboard sounds from the hub itself.
Yes. The battery monitor reads up to ten Victron devices over Bluetooth, and the NMEA 2000 gateway reads position, engines, fuel and wind from the bus.
Yes. The logbook, maintenance, spare parts and documents work on their own; add a device when you want live monitoring.
