Discover the pinnacle of marine autopilot performance tailored specifically for Viking yachts equipped with VIPER steering systems. The Garmin Reactor 40 Steer-By-Wire Corepack delivers unmatched responsiveness, allowing captains to navigate open waters with confidence and ease. Engineered for powerboats that demand precision, this system transforms how you handle long offshore runs, tournament fishing trips, or leisurely cruises, keeping your vessel steady even in challenging sea states.

Advanced Solid-State 9-Axis AHRS Technology

At the heart of the Reactor 40 lies its innovative solid-state 9-axis Attitude Heading Reference System (AHRS). Unlike traditional gyro-based sensors prone to drift and bulkier installations, this compact unit can be mounted almost anywhere on your Viking yacht—in any orientation—without compromising accuracy. The result? Drastically reduced heading error, smoother course holding, fewer rudder adjustments, and optimized power draw. Passengers enjoy a more comfortable ride with less helm feedback, while you focus on the horizon.

Adaptive Response to Real-World Conditions

What sets this autopilot apart is its ability to anticipate and react to dynamic sea conditions. Whether your Viking is pitching through head seas, rolling in beam swells, or carving through crosswinds, the Reactor 40 maintains your intended track with minimal deviation. It intelligently adjusts steering inputs to counteract waves and currents, providing a level of stability that feels almost intuitive. Boaters report it excels during those grueling all-day troll patterns or when pushing through rough inlets, saving wear on both crew and equipment.

Effortless Setup for Quick Time on the Water

Time is precious on the water, so we've streamlined the commissioning and sea trial calibration to be remarkably straightforward. No endless shadow drives or complex alignments—just a few intuitive steps via your compatible Garmin chartplotter, and you're ready to go. This user-centric design respects the busy schedules of Viking owners who prioritize reliability over fuss.

Versatile Modes for Powerboat and Sailing Enthusiasts

• Heading Hold: Locks in your desired direction effortlessly.
• Wind Hold: Ideal for sail-assisted power setups.
• Tack/Jibe Automation: Simplifies maneuvers.
• Step Turns: Precise radius control for fishing patterns.
• Trolling Patterns: Customizable grids and spirals for bait deployment.

Seamless Integration with Your Viking's Garmin Ecosystem

Designed without the GHC 20 display for a cleaner install, this corepack thrives when networked with your existing Garmin chartplotters. Control everything from the helm station, flybridge, or even remotely via compatible MFDs. Unlock advanced capabilities like automated GPS path following when paired with BlueChart charts—perfect for plotting safe routes around shoals or staging grounds. It communicates flawlessly over NMEA 2000, sharing data with radar, sonar, and engine monitors for a unified boating experience. Viking yachts with VIPER steer-by-wire systems benefit from native compatibility, ensuring plug-and-play harmony with factory electronics.

Built for Endurance and Viking Toughness

Garmin's Reactor 40 is ruggedized for the demanding marine environment, with IPX7 waterproofing on key components and robust cabling to withstand salt spray, vibrations, and years of heavy use. Lower power consumption means longer runtime on battery banks during generator-off anchoring, a boon for extended adventures. It's not just an autopilot; it's an investment in safer, more enjoyable voyages aboard your Viking.
