Yacht monitoring
A yacht spends most of its life without its owner aboard. Remote yacht monitoring closes that gap: Cloud Shelter watches the bilge, the battery banks, shore power, smoke, temperature, hatches and the yacht's position around the clock, and sends a clear alert to your phone when something changes.
It is one portal for the whole vessel — live readings, alerts, maintenance, spare parts, the logbook and the yacht's documents on the same record — so nothing important lives only in a skipper's head.
Water first: wireless leak sensors and a two-float bilge monitor report every bilge-pump run, how long it lasted and how high the water rose. A pump that cycles more than usual is flagged as a slow leak days before it becomes a flooded bilge.
Power next: every battery bank — including several lithium packs wired in parallel and up to ten Victron devices — reports state of charge, current and temperature. Shore power is watched too, so you know the moment the yacht is running on its batteries.
How the boat battery monitor works
Door, hatch and motion sensors arm and disarm from the portal or from Telegram. A certified photoelectric smoke alarm sounds aboard and alerts your phone, armed or not — life-safety never waits for an arm switch. If the engine starts or the yacht moves while it is armed, you hear about it.
With the NMEA 2000 gateway, the yacht's own GPS, engines, tanks, depth and wind stream to the portal. Passages are logged automatically, and the anchor watch raises the alarm — siren aboard, alert on your phone — if the yacht drags, moves off the anchorage or the wind turns onto a new quarter.
A yacht throws off thousands of readings a day. Cloud Shelter learns what is normal for your yacht and turns a fault into one plain message — what happened, where aboard and how urgent — with an acknowledge button, instead of a stream of numbers. When the condition clears, you are told that too.
Several yachts sit on one account, each with its own live view, alerts and maintenance plan. Captains and managers can be given access, and the fleet board shows which yacht needs attention first. Connectivity is whatever the yacht already has — marina Wi-Fi, 4G/LTE or Starlink — and readings are buffered aboard while it is offline.
Live monitoring is half of looking after a yacht. Service tasks are planned by date or by engine hours, and engine hours advance on their own from the engine data. The spare-parts register lists what is aboard and where, and registration, insurance and certificates are stored with the yacht — so a captain taking over, a buyer or a surveyor finds the history in one place.
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.
What it does not do: Cloud Shelter does not detect carbon monoxide, and it does not replace a qualified surveyor or a person checking the yacht. The sensors are wireless, but the hub needs power from the yacht's supply.
A yacht monitoring system watches an unattended yacht — water, power, fire, security and position — and alerts the owner or captain when something changes. Cloud Shelter does this in one portal, with alerts to your phone on Telegram.
Yes. Several yachts can sit on one account, each with its own devices, alerts and maintenance, and the fleet view shows which one needs attention.
Yes. The battery monitor reads up to ten Victron devices over Bluetooth Instant Readout, and the NMEA 2000 gateway reads GPS, engines, tanks, depth and wind from the existing backbone.
Readings are buffered aboard and sync when the connection returns. Alerts need the yacht to be online — through marina Wi-Fi, 4G/LTE or Starlink — to reach your phone.
