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.
