Why choose the Compact Reactor 40

• Compact, robust hydraulic autopilot corepack tailored for single-engine outboards on boats under 25’. Take the load off your hands and cruise with confidence at moderate to high speeds.
• Solid-state 9-axis AHRS lets you mount Reactor 40 nearly anywhere and in any orientation, while reducing power consumption and heading error for steadier tracking—even when the sea is pitching or rolling.
• Easy commissioning and calibration setup means you’ll be controlling autopilot quickly, so you can get on the water faster.
• Control from anywhere on board connect with a compatible Garmin chartplotter or the GHC 50 autopilot instrument to steer and adjust routes remotely.
• Shadow Drive technology (optional) automatically disengages the autopilot when you turn the wheel, giving you seamless, intuitive control when needed.
• Advanced navigation features with a compatible chartplotter: heading hold, step turns, wind hold, and tack/jibe when paired with a wind sensor (sold separately); plus Follow Route and Auto Guidance+ for planning and safe navigation.
• Installation and compatibility designed for quick commissioning; mount within 6 feet of the steering cylinder for best results. Not recommended for power-assist installs, engines above 150 horsepower, or boats with more than a 12-degree deadrise.
• Boat suitability crafted for small powerboats and sailing craft under 25 feet, offering a reliable autopilot option without overwhelming complexity.

Whether you’re cruising toward your next destination or simply enjoying time on the water, the Compact Reactor 40 with GHC 50 and Shadow Drive delivers steady course control, reduced manual steering, and intelligent features that enhance your sailing or powerboating experience. Note: Auto Guidance is for planning purposes and does not replace safe navigation.
