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.
