Garmin BlueNet™ Marine Network Cable - 50'

Enhance Your Vessel's Connectivity with Extended Reach

Picture this: you're out on the water, managing a complex setup of chartplotters, radars, and sensors spread across your boat. Short cables just won't cut it for those longer runs from the helm to the engine room or across the deck. That's where this robust 50-foot solution steps in, providing the flexibility to create a seamless marine network without compromising on performance or reliability.

Crafted specifically for harsh saltwater environments, it delivers consistent data transmission essential for real-time navigation and safety features. Whether you're retrofitting an older vessel or building a cutting-edge helm station, this cable ensures your Garmin ecosystem communicates flawlessly, even over greater distances.

Engineered for Marine Demands

• Durable Construction: Double-shielded to resist electromagnetic interference from engines, radios, and other onboard electronics, maintaining signal integrity on long runs.
• Weatherproof Design: Fully sealed connectors that withstand constant exposure to spray, UV rays, and temperature swings common in marine settings.
• High-Speed Data Flow: Supports the bandwidth needed for sharing sonar data, radar overlays, and autopilot commands across multiple devices without lag.
• Easy Integration: Plug-and-play compatibility with Garmin's marine network ports, reducing installation headaches.

Unlike generic Ethernet cables that corrode or fail in wet conditions, this marine-grade option is built to last seasons without signal degradation, saving you from frequent replacements.

Real-World Applications on Board

For sailboats with distributed electronics or larger powerboats needing to network from bow-mounted transducers to aft radars, the 50-foot length bridges gaps that shorter cables can't. Installers often use it to connect a central hub in the console to remote displays in the cabin, ensuring every crew member has access to the same critical info.

It's particularly valuable in multi-station setups, like flybridge and lower helm configurations, where routing around bulkheads and through tight conduits demands extra length without excess slack that could snag.

Seamless Compatibility Across Garmin Systems

This cable pairs perfectly with a wide array of Garmin marine devices, from GPSMAP series chartplotters to GXM satellite receivers and GHX transducers. It extends your network backbone, allowing you to daisy-chain units for expanded coverage without needing separate wiring runs.

Pro tip: For optimal performance, combine it with Garmin's network expanders in high-device-count systems to distribute load evenly and prevent bottlenecks.

Installation Best Practices for Long-Term Reliability

Start by planning your route: Avoid sharp bends near exhausts or high-vibration areas. Use cable ties sparingly to prevent chafing, and secure with marine-grade clamps every 18-24 inches. During routing, test continuity at both ends before finalizing connections to catch any pinched wires early.

Once installed, power cycle the network to verify all nodes recognize each other. Regular visual inspections during routine maintenance catch wear before it affects operation—look for cracks in the jacket or loose plugs.

"On a recent refit, running this cable from the radar arch to the salon display transformed our navigation reliability. No more dropouts during rough seas."

Caring for Your Investment

To maximize lifespan, rinse with fresh water after saltwater exposure and store excess length coiled loosely in dry bilge areas. Avoid direct contact with fuels or oils, which can degrade the insulation over time. With proper care, it handles years of demanding use without faltering.
