Raymarine SeaTalk Highspeed Patch Cable - 5m

Seamless Connectivity for Your Raymarine G Series Network

Imagine cruising through choppy waters with crystal-clear radar images, real-time sonar data, and intuitive chartplotter updates all syncing effortlessly across your displays. That's the power of a reliable high-speed network backbone. This 5-meter SeaTalk HS patch cable steps in as the unsung hero, linking your Raymarine G Series multifunction displays, radars, and sensors with gigabit Ethernet speeds over rugged RJ45 connectors. No more laggy data transfers or dropped connections when conditions get rough— just smooth, dependable performance that keeps you focused on the horizon.

Crafted from marine-grade materials, this gray cable withstands saltwater spray, UV exposure, and constant vibration, ensuring your setup stays operational season after season. At 16.5 feet, it offers the perfect reach for most helm configurations without excess clutter, making it a go-to for both weekend warriors and serious offshore adventurers.

Why High-Speed SeaTalk Matters on the Water

SeaTalk HS isn't your average Ethernet cable—it's optimized for marine environments, delivering up to 100 Mbps of bandwidth for high-resolution video feeds, fast chart redraws, and multi-device data sharing. Pair it with G Series systems to unlock networked features like shared radar overlays on multiple screens or synchronized autopilot adjustments. Boaters report fewer frustrations during long hauls, as this cable minimizes interference from nearby engines or electronics, thanks to its shielded twisted-pair design.

• Lightning-Fast Data Flow: Handles heavy loads from HD radar, digital sounders, and IP cameras without bottlenecks.
• Plug-and-Play Simplicity: RJ45 ends snap into place securely, no special tools needed for most installs.
• Battle-Tested Durability: Flex-resistant jacket shrugs off bends and pulls common in dynamic boat layouts.

Easy Installation Tips for Peak Performance

Getting this cable up and running takes minutes. Start by powering down your G Series units, then route the cable along existing cable trays or through conduits to avoid sharp edges. Connect one end to the SeaTalk HS port on your primary display or network switch, and the other to a secondary unit or spur. Use cable ties sparingly to prevent pinching, and test the network via the system's diagnostics menu—look for green link lights confirming gigabit negotiation.

Pro tip: In humid climates, keep connections dry with dielectric grease on the RJ45 pins to fend off corrosion. For longer runs, daisy-chain multiple cables via HS switches to expand your network without signal loss.

Real-World Advantages for Boaters

Fishermen love how it streams live sonar and structure scan data across screens, spotting bait balls faster. Sailors rely on it for precise wind instrument integration during races, while powerboaters appreciate the stability for thermal imaging at night. Its low-profile gray sheath blends into console designs, reducing snag hazards. Over time, this investment pays off by cutting downtime—no more troubleshooting flaky connections mid-trip.

Perfect Fit for Raymarine G Series Ecosystems

Engineered specifically for G Series chartplotters, radars, and instruments, this cable ensures full compatibility without adapters. It supports the proprietary SeaTalk HS protocol atop standard Ethernet, so your legacy SeaTalk1 devices stay connected via gateways. Whether upgrading from older networks or building anew, it forms the reliable spine of a scalable marine electronics suite.
