Manufacturer

Simrad

<p>Founded in 1946 by Norwegian scientist Willy Simonsen, Simrad has established itself as a pioneering force in marine electronics technology. Born from the union of distinguished marine technology pioneers including Robertson, Simonsen Radio, Shipmate and Navico, the brand represents decades of experience in marine autopilot, communications, satellite navigation, electronic chartplotters, echosounders, instrumentation and multifunction displays. The company diversified in the late 1940s into the design and production of echo sounders, followed by fish-finders, sonars, radars and navigation equipment, establishing a worldwide reputation for quality that continues today.</p><h3>Precision Navigation and Display Technology</h3><p>Simrad's extensive lineup of <a href="/11289-simrad-simrad-multi-function-display-systems-200956">multi-function display systems</a> delivers exceptional performance for powerboats and luxury cruisers of all sizes. The brand has become the choice for demanding customers from explorers and adventurers to premium yacht builders and charter captains, with products covering recreational vessels from small runabouts and sportfishing boats to luxury cruisers and superyachts. These advanced systems integrate GPS navigation, fish-finding sonar, and vessel monitoring in intuitive touchscreen interfaces designed for all-weather operation.</p><h3>Advanced Radar and Autopilot Systems</h3><p>At the heart of safe navigation lies Simrad's comprehensive range of <a href="/11289-simrad-simrad-radars-autopilots-200957">radars and autopilots</a>. One of Simrad's most influential contributions came with the launch of solid state Broadband Radar in 2009, followed by Halo radar technology. The current range of Simrad autopilots represents over 70 years of experience and development, with a wide range of solutions to suit any vessel type and length. These systems compensate for wind and tide, freeing operators from constant course corrections during fishing, cruising, or navigation planning.</p><h3>Modular System Architecture</h3><p>What sets Simrad apart is the modular approach to marine electronics integration. Boaters can start with core components and expand their systems over time with <a href="/11289-simrad-simrad-sounder-modules-200958">sounder modules</a> and <a href="/11289-simrad-simrad-accessories-200955">accessories</a> tailored to specific needs. Industry-standard NMEA 2000 connectivity ensures seamless integration between displays, sensors, and control systems throughout the vessel, whether building a simple single-display setup or a comprehensive multi-station command center.</p><h3>Built for Harsh Marine Environments</h3><p>After World War II, Simrad's engineering mindset shifted to the marine world, producing rugged radio telephones for fishing vessels, and by the 1950s, Simrad had earned a reputation for equipment that worked reliably in harsh conditions—a reputation that defines the brand today. That legacy of durability and purpose driven design continues to guide Simrad's modern product range, with long term investment in specialist engineering, particularly in radar, sonar and system integration. From commercial fishing operations to recreational sportfishing and luxury yacht applications, Simrad electronics are engineered to perform when it matters most.</p>

Product Details

The Simrad NAC-D is a steer-by-wire autopilot computer designed specifically for Electronic Vessel Control (EVC) systems with digital steering interfaces. This innovative solution brings full-featured Simrad autopilot performance to boats equipped with SeaStar Optimus, Yanmar VC10/JC10, Volvo IPS/EVC, or Yamaha Helm Master and single-engine ECM control systems.

Simplified Installation and Setup

The NAC-D eliminates the complexity of traditional autopilot installations by requiring only two Micro-C connector hookups. There's no need for an additional hydraulic pump, rudder sensor installation, or dockside rudder calibration, saving both installation time and cost while reducing potential points of failure.

Key Features:

  • Direct interface with SeaStar Solutions, Volvo, Yanmar, and Yamaha approved control systems
  • Continuum steering technology with SteadySteer feature for precise course holding
  • Automatic switching between dual-speed profiles for optimal performance at low and high speeds
  • Compatible with AP 44 and AP 48 dedicated autopilot controllers
  • Advanced steering patterns including waypoint navigation, heading hold, U-turns, spiral turns, and zigzag maneuvers
  • CAN-bus data network connectivity for seamless system integration
  • No additional hydraulic components or sensors required

Backed by over 70 years of Simrad autopilot development and expertise, the NAC-D reduces operator workload and fatigue while improving situational awareness and overall vessel safety. The system's intelligent steering algorithms deliver consistent performance across all speed ranges, helping you arrive at your destination fresher and more alert.

Great!

Would have gotten 5 stars but product info was not stated correctly.

easy to navigate website,great prices and quality name brands.

Website for a little funky after selecting items

Fast purchasing process

none

Great prices

I was hesitant about buying the product because it was almost a $100 cheaper than a couple other websites. I went ahead and did it and couldn't believe when I got it the next day. I did pay a little extra for shipping but it was totally worth it.
