Imagine streamlining your cockpit or mast setup without a tangle of cables snaking across your boat. The Nemesis™ Hub from B&G transforms how you connect multiple Nemesis 9 or Nemesis 12 sailing displays, making installation cleaner, more reliable, and ready for the demands of competitive racing or long-distance cruising. By centralizing power and data through a single Ethernet run, it cuts down on wiring clutter while ensuring seamless communication between displays for wind, speed, laylines, and tactical data.
Why Sailors Choose the Nemesis™ Hub
Effortless Multi-Display Connectivity: Link up to three Nemesis displays in tight spaces like the masthead, helm, or cockpit using short 0.6m interconnect cables—perfect for keeping things tidy during high-speed maneuvers.
Single Cable Simplicity: One main Power/Ethernet cable handles everything, with flexible lengths available to match your boat’s layout, reducing installation time and potential failure points.
Rugged Marine Design: Built to thrive in harsh saltwater environments, it shrugs off spray, submersion, and extreme temperatures, so your instruments stay online when conditions turn brutal.
Seamless Network Integration: Plays nicely with NMEA 2000 and Ethernet networks, sharing critical data like polar tables, start lines, and heading info across your entire suite of B&G electronics.
Real-World Installation Insights
Setting up the hub is straightforward for most DIY sailors. Mount it securely near your displays—perhaps behind a panel at the helm or inside a mast tube. Connect the main Power/Ethernet cable to your boat’s 12/24V supply, then daisy-chain the short interconnects to each Nemesis screen. Ground it properly with the M4 stud for electrical safety, especially in lightning-prone areas. Pro tip: Use zip ties and conduit for the runs to protect against UV and chafe, ensuring years of vibration-free performance on a lively race boat.
For racing teams, position one hub at the mast for wind instruments and another at the helm for tactician views—this setup delivers synchronized data without latency, giving you an edge on the racecourse. Cruisers appreciate the reduced weight aloft and easier troubleshooting during passages.
