Fleet GPS tracking
With a Teltonika GPS tracker on board, SunSea Hub shows each boat’s position, speed, fuel and battery, records its trips, and sends WhatsApp alerts: leaving the zone, water ingress, impact, departure without a rental, low fuel or battery. The owner of a managed boat sees their boat’s position and alerts.
The fleet, live
With a GPS tracker on board, Fleet shows each boat’s position, speed, fuel level and battery, the navigation zones and ports, and sends WhatsApp alerts: leaving the zone, water ingress, impact, departure without a rental, low fuel or battery.

Navigation zones, no-go zones, ports
The rental company draws its zones: the area allowed for its rentals, no-go zones, ports. The tracker reports a boat leaving the zone, and moving away from a port.
Alerts
- Leaving the zone and entering a no-go zone.
- Water ingress and impact.
- Departure with no rental in progress.
- Low fuel or battery.
Alerts are sent by WhatsApp and remain in Fleet.
For owners
In Sup, the owner sees their boat’s position, track and readings, and the alerts that concern it; they can arm a mooring alarm. See owner management.
