Simrad NAC-D – Digital Steering Autopilot
NAC™ -D is a digital steering autopilot solution for Electronic Vessel Control Systems (steering systems with a digital interface). It allows automatic switching between two speed profiles, delivering optimal steering performance at both low and high speeds. It comes with Continuum® steering and the new SteadySteer™ feature.
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 new 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.
*Steer-by-wire – digital steering, the steering signal between autopilot and actuator/pump/rudder is in the form of a digital communication protocol.
**Continuum steering – an autopilot algorithm technology based on decades of development, distilling countless hours of real world on-water experience into a system you can trust to take the helm.
***SteadySteer – an autopilot functionality allowing boaters to take immediate, manual control of the vessel through turns without having to disengage the autopilot.
