Meet the Garmin OnDeck Hub — a fully integrated remote connectivity solution that lets you track, monitor, and control up to 5 switches on your boat from anywhere. Stay in touch with your vessel, receive real-time alerts, and manage critical systems with the press of a button through the ActiveCaptain app.

• Control up to 5 relay switches — power and operate essentials like battery chargers, ice makers, lighting, and more from afar.
• Always-on connectivity — secure remote access via 3G/4G networks and seamless integration with Garmin Marine Network and NMEA 2000 sensors.
• ActiveCaptain app — manage alarms, monitor vessel data, and take control from your compatible smartphone.
• Security and geofence alerts — be alerted by text 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 data.
• Battery backup — a 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).

What makes OnDeck Hub essential on every vessel

With the OnDeck Hub, peace of mind is a plan you can count on. Get timely updates about battery status, bilge activity, shore power, and temperature changes, and receive alerts the moment something requires attention. Turn on or off critical systems remotely to prepare your boat for docking, starting, or storage, all while staying connected to your vessel through ActiveCaptain.
