Discover Seamless Steering with Reactor 40 for Your Viking Yacht

Imagine cruising the open ocean on your Viking yacht, the horizon stretching endlessly ahead, without constantly adjusting the helm. The Garmin Reactor 40 steer-by-wire corepack, tailored specifically for Viking VIPER systems, delivers that freedom. Paired with the GHC 50 autopilot instrument, it transforms how you navigate, letting you focus on the thrill of the journey rather than the grind of manual steering.

Built for the demanding marine environment of luxury sportfishing yachts, this system stands out with its intuitive design. Yacht owners rave about how it handles rough seas effortlessly, maintaining your course through swells and chop without a hitch. It's not just an autopilot—it's a reliable crew member that enhances every outing.

Advanced Solid-State Technology for Flexible Installation

At the heart of the Reactor 40 is a solid-state 9-axis AHRS (Attitude Heading Reference System). This cutting-edge sensor array means you can install the corepack almost anywhere on your Viking yacht—upright, inverted, or sideways. No more wrestling with rigid mounting constraints or worrying about alignment.

Lower power draw and minimized heading errors translate to longer battery life and pinpoint accuracy, even in dynamic conditions. Whether you're trolling for marlin or crossing swells, it keeps you steady, reducing fatigue on long passages.

Reactive Performance That Matches the Sea

Sea states change fast—pitching, rolling, yawing—and so does the Reactor 40. Its adaptive algorithms respond in real-time, holding your heading with confidence. Skippers appreciate how it smooths out the ride, making offshore runs more comfortable for everyone aboard.

Calibration? A breeze. What used to take hours now wraps up in minutes, so you're back on the water faster. No complex setups or trial-and-error—just plug in, follow the prompts, and go.

Full-Boat Control at Your Fingertips

Why limit control to the helm? Integrate with your Garmin chartplotter or the included GHC 50, and command the autopilot from anywhere. Use the Reactor remote, compatible quatix smartwatches, or even your chartplotter's touchscreen. It's a networked system that puts you in charge, no matter where you stand.

For powerboat enthusiasts, enjoy heading hold and step turns. Sailing features like wind hold and automated tack/jibe unlock when you add a wind sensor. Paired with Garmin's ecosystem, tap into follow route capabilities and Auto Guidance+ for smarter trip planning.
