Maretron

<h3>Maretron: Intelligent Vessel Monitoring &amp; Control</h3><p><strong>Maretron</strong> has long been recognized as a leading innovator in marine electronic instrumentation, <a href="/11272-maretron">designing and manufacturing advanced monitoring and control systems</a> for recreational and commercial mariners alike. Now part of the Raymarine family, Maretron's product ecosystem continues to set the standard for vessel intelligence, safety, and operational efficiency on the water.</p><p>At the heart of the Maretron platform is the open <strong>NMEA 2000&reg;</strong> standard — an industry-wide protocol that allows electronic equipment from multiple manufacturers to communicate seamlessly over a single network backbone. Maretron was among the first companies to offer NMEA 2000&reg;-approved cables and connectors, and that commitment to interoperability remains central to everything they build.</p><h3>A Complete Ecosystem for the Modern Vessel</h3><p>Maretron's product range spans nearly every monitoring need a mariner might have. Their <strong>vessel monitoring and control</strong> hardware includes touchscreens, black box display servers, and alarm modules that put critical data at your fingertips — whether you're at the helm, below deck, or monitoring your boat remotely via the MConnect&reg; web server. MConnect integrates with over 400 NMEA 2000 data points, delivering real-time feedback through customizable graphics on chartplotter displays or any browser-enabled device.</p><p>Engine health is a top priority for any serious boater. Maretron's <strong>engine monitoring modules</strong> track vital parameters like oil pressure, coolant temperature, RPM, and fuel flow, providing programmable alerts before minor issues become costly problems. Their <strong>electrical monitoring</strong> lineup covers both AC and DC systems, helping owners keep tabs on battery voltage, current draw, and shore power status across the entire vessel.</p><p>For boat owners who need to track fluid levels, Maretron's <strong>tank monitoring</strong> solutions connect to resistive tank senders from leading manufacturers, converting analog readings into NMEA 2000 digital data. Navigation-focused products include the WSO200 Ultrasonic Wind and Weather Station, the DST110 Depth/Speed/Temperature Triducer, the GPS200 GPS Antenna/Receiver, and the SSC300 Solid State Compass — each engineered to deliver dependable data in demanding marine environments.</p><h3>Built to Withstand the Marine Environment</h3><p>Every Maretron product is tested and certified to the <strong>IEC 60945 standard</strong> for Maritime Navigational and Radiocommunication Equipment and Systems. Electronics — even those installed below deck — are housed in watertight enclosures engineered for years of reliable service in saltwater, humidity, and vibration. Gold-plated terminals, nickel-plated brass connectors, and triple-shielded cabling reduce EMI and prevent the corrosion that ends the life of lesser marine electronics.</p><p>The <strong>MPower&reg; Digital Switching</strong> platform extends Maretron's capabilities into DC electrical system control, allowing boaters to manage circuits via configurable keypads, switch modules, and chartplotter integration. The <strong>OctoPlex</strong> power distribution system takes this further, offering complete AC and DC control with significant savings in wiring weight and installation complexity.</p><h3>Why Mariners Choose Maretron</h3><ul style="list-style:disc"><li>Pioneer of NMEA 2000&reg;-approved cables and connectors</li><li>Full ecosystem: sensors, displays, gateways, switches, and software</li><li>IEC 60945-certified for harsh maritime environments</li><li>MConnect&reg; enables remote vessel monitoring from any browser-enabled device</li><li>Compatible with engines from Caterpillar, Cummins, Yanmar, Volvo Penta, and more</li><li>Now backed by Raymarine's global support network</li></ul><p>Whether you're outfitting a coastal sailboat, a long-range trawler, or a commercial workboat, Maretron delivers the tools to keep you informed, in control, and safe on the water.
