Raymarine RNS-8 8-Port Gigabit Network Switch

The Raymarine RNS-8 8-Port Gigabit Network Switch is the backbone of modern integrated marine electronics systems, designed for serious anglers and cruising boaters who demand reliable data distribution across multiple onboard devices. Whether you're running networked GPS chartplotters, sonar units, autopilot systems, or multiple multifunction displays, this switch consolidates all your marine electronics into a single, cohesive network. Built specifically for the harsh marine environment, it handles the electrical noise, salt spray, and vibration that comes with extended time on the water without compromise.

With eight Gigabit Ethernet ports operating at 1000 Mbps, the Raymarine RNS-8 delivers the bandwidth needed to stream real-time sonar data, chart updates, and radar imagery simultaneously across your vessel's network without latency or bottlenecking. The switch automatically manages network traffic through intelligent switching architecture, ensuring that your autopilot system, chartplotter, and sonar never compete for bandwidth. At just 2 pounds, it integrates seamlessly into engine rooms or helm stations, and its compact design fits into tight spaces common in modern boat installations without sacrificing port density or cooling performance.

Boaters running Raymarine's full ecosystem—including gS Series chartplotters, Quantum radar, AXIOM displays, and SeaTalk hs network devices—benefit most from this switch's native compatibility and optimized handshaking protocols. Installation requires standard marine-grade Ethernet cabling and a 12/24V DC power source, making it accessible to both professional installers and experienced DIY technicians. For vessels with multiple integrated systems, the RNS-8 eliminates daisy-chaining concerns and reduces single-point failure risk, giving you redundancy and peace of mind during long offshore passages or competitive fishing tournaments.
