Simrad NAC-1 Autopilot Computer Product Description
Simrad NAC-1 Autopilot Computer
Professional autopilot control computer with Continuum Steering technology - the intelligent brain behind hydraulic and cable-steered autopilot systems for vessels up to 30 feet.
The Simrad NAC-1 autopilot computer serves as the central processing unit for sophisticated marine autopilot systems, combining advanced steering algorithms with plug-and-play installation simplicity. Engineered for boats up to 30 feet (9 meters) in length, this computer interfaces seamlessly with Simrad drive units, heading sensors, and multifunction displays to deliver precise, reliable course-keeping performance.
Advanced Continuum Steering Technology
Built on Simrad's proven Continuum Steering technology, the NAC-1 provides intelligent steering control that continuously analyzes vessel performance and sea conditions. This advanced processing ensures smooth course corrections and optimal steering response across varying conditions, from calm waters to challenging offshore environments.
Flexible Drive Unit Compatibility
The NAC-1 is specifically engineered to drive both the Simrad PUMP-1 reversible hydraulic pump for hydraulic-steered outboard systems and the HELM-1 cable steer drive unit for mechanically-steered vessels. This versatility makes it suitable for a wide range of boat configurations while maintaining consistent performance standards.
Revolutionary Virtual Rudder Feedback
Simrad's exclusive Virtual Rudder Feedback technology eliminates the need for separate rudder feedback units on outboard and sterndrive boats with planing hulls. This innovation reduces system complexity, installation costs, and maintenance requirements while providing accurate steering feedback through advanced algorithmic processing.
Key Features & Benefits
- Continuum Steering Technology: Advanced steering algorithms for precise course-keeping performance
- Dual Drive Compatibility: Works with PUMP-1 hydraulic and HELM-1 cable steer drive units
- Virtual Rudder Feedback: Eliminates need for separate feedback units on outboard/sterndrive boats
- NMEA 2000 Connectivity: Industry-standard networking for seamless system integration
- Plug-and-Play Installation: Simplified wiring with standardized connectors

- Multifunction Display Integration: Works with Simrad chartplotters and displays
- Professional-Grade Reliability: Marine-rated electronics for harsh saltwater environments
- Compact Design: Space-efficient installation in engine rooms and electronics compartments
Technical Specifications
System Requirements
The NAC-1 requires specific components to create a complete autopilot system:
- Drive Unit: PUMP-1 (hydraulic) or HELM-1 (cable steer)
- Heading Sensor: NMEA 2000 compatible compass or GPS heading sensor
- NMEA 2000 Network: Backbone, terminators, and power supply
- Controller: Compatible autopilot controller or Simrad multifunction display
- Rudder Feedback: RF25 unit (if required) or Virtual Rudder Feedback
Installation & Integration
The NAC-1's plug-and-play design minimizes installation complexity through standardized connectors and NMEA 2000 networking. The computer mounts in a dry, protected location and connects to the vessel's NMEA 2000 backbone for communication with heading sensors, displays, and other navigation equipment.

Frequently Asked Questions
What's the difference between Virtual Rudder Feedback and traditional rudder feedback?
Virtual Rudder Feedback uses advanced algorithms to calculate rudder position based on steering input and boat response, eliminating the need for a physical rudder feedback sensor. Traditional RF25 feedback units physically measure rudder angle and are required for some vessel types or when maximum precision is needed.
Which drive unit should I choose for my boat?
PUMP-1 is designed for boats with hydraulic steering systems (most outboards and sterndrives), while HELM-1 is for cable-steered vessels with mechanical helm systems. Check your steering system type or consult a marine electronics professional for proper selection.
Can the NAC-1 work with non-Simrad displays and sensors?
Yes, the NAC-1 uses standard NMEA 2000 networking, making it compatible with most NMEA 2000 heading sensors and multifunction displays from various manufacturers. However, some advanced features may only be available with Simrad displays.
What size boats is the NAC-1 suitable for?
The NAC-1 is specifically designed for boats up to 30 feet (9 meters) in length. For larger vessels, consider the NAC-2 or NAC-3 autopilot computers which provide higher power output and additional features for bigger boats.
Is professional installation required?
While the plug-and-play design simplifies installation, proper NMEA 2000 network setup and drive unit installation typically require marine electronics experience. Professional installation ensures optimal performance, proper calibration, and warranty compliance.
The NAC-1 is the center of your autopilot system, containing the electronics needed to operate and interface with other key components. It has been designed for hydraulic or cable-steered boats up to 30 Feet in length and works with Lowrance displays to provide a fully integrated autopilot solution.
