Simrad 000-15621-001 NAC-D Autopilot Computer for Steer-By-Wire Systems

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.
