Simrad AC70 Autopilot Computer

The Simrad AC70 Autopilot Computer is the command center for modern vessel automation, purpose-built for recreational and professional boaters who demand precision steering over extended passages. Whether you're running a long offshore route, holding a heading in challenging sea states, or managing fatigue during multi-day cruises, this autopilot controller transforms how you navigate. The AC70 integrates seamlessly with Simrad's navigation ecosystem, giving you hands-free control that responds intelligently to wind, current, and helm input variations.

Built as a dedicated autopilot computer, the AC70 processes real-time data from your vessel's heading sensor and cross-track error inputs to maintain course with minimal deviation. The unit weighs 10 lbs and is engineered for robust saltwater environments, featuring marine-grade construction that resists corrosion and electrical interference common at sea. Its intelligent control algorithms adapt to different sea conditions and vessel types, from displacement cruising sailboats to high-speed powerboats, making it one of the most versatile autopilot solutions in its class.

The Simrad AC70 Autopilot Computer works best for captains upgrading legacy systems or integrating with existing Simrad chartplotters and navigation displays. Installation requires connection to compatible helm hardware, rudder feedback sensors, and a primary nav source—standard on modern vessels with integrated bridge systems. Boaters appreciate its reliability during night passages and autopilot-dependent fishing operations where crew focus matters on deck work rather than helm management.
