Stay Connected to Your Boat No Matter Where You Are
Imagine docking your vessel after a long day on the water, knowing you can check its status with a quick glance at your phone. The Garmin OnDeck Hub transforms how boat owners manage their crafts remotely, offering robust tracking, real-time monitoring, and effortless control. Whether you’re miles away at home or traveling abroad, this hub delivers peace of mind through seamless integration with your existing marine setup.
Designed for serious mariners who value reliability, the OnDeck Hub leverages an always-on cellular connection to keep you informed about critical systems. From detecting unauthorized movement to prepping your boat for launch ahead of time, it addresses common concerns like theft, battery drain, and unexpected issues that arise when you’re not aboard.
Three Pillars of Boat Management: Track, Monitor, and Control
Precise Tracking for Security
Equip your boat with built-in GPS that reports position updates every 15 to 30 minutes, adapting to power levels for efficiency. Set up virtual geofences around marinas or moorings—step outside, and receive instant text alerts. Paired with a dedicated security sensor, you’ll know immediately if doors open or intruders tamper with your gear, minimizing risks during storage seasons.
Comprehensive Monitoring
Keep tabs on vital stats like dual battery voltages, bilge pump activity, shore power status, and cabin temperatures. NMEA 2000 compatibility pulls in data from fluid levels, engine hours, water depth, wind speeds, and more. Customize alarms in the ActiveCaptain app for proactive alerts, ensuring small problems don’t escalate into costly repairs.
Remote Control at Your Fingertips
Activate up to five relay switches from anywhere—turn on battery chargers to top off power before arrival, fire up the ice maker for a cold drink upon boarding, or test systems remotely. This feature shines for weekend warriors who want everything ready without hauling extra gear or waiting for on-site checks.
Seamless Integration with Your Marine Ecosystem
The OnDeck Hub slots perfectly into Garmin’s world, connecting via Garmin Marine Network to multifunction displays (MFDs) and NMEA 2000 networks. Sync with engines for fuel flow and warning indicators, or environmental sensors for depth and speed data. All vessel insights store securely in the cloud for up to 30 days, accessible anytime through the intuitive ActiveCaptain app on your smartphone.
With Wi-Fi, 3G/4G cellular, and a 48-hour backup battery, connectivity stays rock-solid even if main power fails. This resilience proves invaluable during power outages or when leaving your boat unattended for extended periods.

Pro Tips for Maximizing Your OnDeck Experience
Position the hub in a dry, ventilated spot for optimal antenna performance. Regularly update the ActiveCaptain app for new features, and test geofences during calm weather to fine-tune boundaries. Pair it with solar maintainers for year-round battery health monitoring—boaters report fewer surprise service calls after installation.
