Simrad NAC-D Autopilot Computer for Steer-By-Wire Systems

NAC-D Autopilot Computer for Steer By Wire

NAC-D is a steer-by-wire autopilot solution for Electronic Vessel Control Systems (steering systems with a digital interface).

With NAC -D, boaters with SeaStar Optimus, Yanmar VC10/JC10, Volvo IPS/EVC or Yamaha helm master/single-engine control systems can benefit from all the full features and performance of Simrad autopilots.

Easy to install

Requires only the connection of two Micro-C connectors there is no requirement for an additional hydraulic pump, rudder sensor installation, or dockside rudder calibration. This saves boaters time and money.

Automatic switching

Featuring Continuum steering and support for the SteadySteer, the NAC -D allows automatic switching between two-speed profiles delivering optimal steering performance at both low and high speeds.

Flexible choice

Choose the controller to suit your preference from dedicated controllers like the AP 44 or AP 48.

Simrad autopilot systems incorporate state-of-the-art electronics and represent over 70 years of experience and development. Simrad autopilots can reduce your workload and fatigue and improve your situational awareness and safety, helping you arrive fresher at your destination.

The Simrad NAC-D Autopilot Computer is a sophisticated steer-by-wire solution designed for modern electronic vessel control systems. Compatible with SeaStar Optimus, Yanmar VC10/JC10, Volvo IPS/EVC, and Yamaha Helm Master single-engine controls, the NAC-D offers seamless integration and advanced autopilot functionality. Its design emphasizes ease of installation, requiring only the connection of two Micro-C connectors, eliminating the need for additional hydraulic pumps, rudder sensors, or dockside rudder calibration, thereby saving both time and money for boaters. This streamlined setup simplifies the upgrade process and reduces onboard complexity. The NAC-D features automatic switching capabilities, including Continuum steering and support for SteadySteer, allowing the system to automatically transition between two-speed profiles for optimal steering at both low and high speeds. This ensures smooth and precise control whether cruising or maneuvering at slow speeds, enhancing safety and confidence during navigation. Boaters can choose from dedicated controllers like the AP 44 or AP 48, providing flexibility to match their preferred control interface. Built upon over 70 years of experience, Simrad autopilots incorporate cutting-edge electronics that help reduce workload and fatigue while increasing situational awareness. This system supports control via CAN-bus data connectivity, enabling integration with Optimus steering systems through the CAN-bus network. The NAC-D can steer to waypoints, set headings, or execute complex turn patterns such as U-turns, spiral turns, or zigzags, making it a versatile addition to any modern vessel. Its compatibility with multiple control systems and features like SteadySteer make it an ideal solution for enhancing navigational safety and convenience on a variety of boats.
