Live monitoring

The boat, right now — not five minutes ago.

Position, speed, heading, depth, tanks and battery, streamed straight from the instruments. The readouts move because the vessel does.

  • One glance covers nav, power and tanks
  • Snapshots refresh on a 60-second cadence
  • Works onboard with no connection at all

Fleet map & history

Your whole fleet on one chart, back through time.

Every vessel as a live pin, colour-coded by status. Scrub back through 60 minutes, 24 hours, 7 days or 30 days to see exactly where a boat has been.

  • Tracks rendered from minute-bucketed history
  • Click any pin for live detail and a jump to the vessel
  • Filter by underway, anchored or in-alarm

Alarms & notifications

Told the moment it matters — and no sooner.

Thresholds on any value, evaluated as data arrives. Debounce and cooldown keep a flapping sensor from burying you, and every alert says exactly where it came from.

  • Email and mobile push, per vessel and recipient
  • Source labels: Cerbo, PLC, VN-Core or Victron
  • Acknowledge and track state across the fleet

Geofencing

Draw a line on the water and let it watch.

Circles or polygons on the chart trigger the instant a vessel crosses them. Anchor watch, restricted zones, expected routes — set once and forget.

  • Entry and exit alerts on any zone
  • Anchor-watch with a configurable swing radius
  • Per-zone recipients, separate from system alarms

NMEA decoding

It speaks the language your instruments already do.

NMEA 0183, NMEA 2000 and AIS, decoded onboard. VesselNow connects to the bus you've already got — Furuno, B&G, Garmin — rather than asking you to replace it.

  • Standard PGNs decoded into clean telemetry
  • AIS targets tracked alongside your own vessel
  • No new wiring — it taps the existing backbone

Victron & power

Battery, solar and tanks, straight from the Cerbo.

VesselNow pulls Victron telemetry over MQTT and Modbus, so state of charge, solar yield and every tank level land in the same live view as your nav data.

  • Cerbo GX integration via Signal K or direct
  • Thresholds on SoC, tank levels and temperatures
  • A CerboGX can raise alerts on its own token

Open API

Token-scoped, spoof-proof, built to integrate.

VN-Core streams to the cloud over a clean REST surface. Vessel identity always comes from the token, never the request body — so a vessel can only ever report as itself.

  • FleetView tokens scope every request to one vessel
  • Endpoints for history, alerts and telemetry ingest
  • Admin endpoints lockable to your office IP
