Garmin OnDeck Hub is a fully integrated remote connectivity solution designed for boats. It lets you track, monitor, and remotely control up to five relay switches from anywhere, keeping you connected to your vessel through the ActiveCaptain app.
-
Remote relay control: Power and operate essentials like battery chargers, ice makers, lighting, and other systems from afar.
-
Global connectivity: Secure remote access via cellular 3G/4G with Wi‑Fi and seamless integration with Garmin Marine Network.
-
ActiveCaptain app integration: Manage alarms, monitor vessel data, and take control from your compatible smartphone.
-
Security and geofence alerts: Receive text alerts if a sensor is triggered or your boat moves outside a defined area.
-
GPS tracking and data history: GPS updates every 15 or 30 minutes (power-dependent) with cloud storage for up to 30 days of history.
-
Battery backup: 48-hour internal backup battery keeps OnDeck accessible even if the boat battery is depleted or power is disconnected.
-
Comprehensive sensor suite: Monitor bilge activity, battery voltage, shore power, temperature, depth, position, wind data, fuel flow, engine hours, and more via NMEA 2000 sensors.
-
Simplified setup and compatibility: Designed to integrate with your existing marine electronics (MFD via Garmin Marine Network and NMEA 2000 sensors).
-
Compact, efficient hardware: 20 W max power draw at 10 Vdc and flexible mounting options to fit your vessel dimensions.
-
Connectivity ecosystem: NMEA 2000 compatible; ActiveCaptain compatible; Cellular connectivity (3G/4G); Wi‑Fi; Garmin Marine Network.
With OnDeck Hub, you gain peace of mind through timely updates on battery status, bilge activity, shore power, and temperature changes. Remotely turning on or off critical systems helps you prepare for docking, starting, or storage, all while staying connected to your vessel via ActiveCaptain. The robust sensor network provides actionable insights, while the 48-hour battery backup ensures continued access even during power interruptions.
