With a complete package designed for powerboats and sailboats, Garmin brings
an advanced marine technology to the boating public that was once only
available for commercial boats. The Reactor 40 autopilot series is simply the
most responsive autopilot system we have ever offered.
Reactor 40 autopilots are very versatile. Both powerboat and sailing features
are available in all corepacks, including heading hold, wind hold, tack/jibe,
step turns and more; simply pick the autopilot that’s compatible with your
existing steering system.
The Reactor 40 hydraulic autopilot corepack is ideal for all types of
hydraulically steered powerboats — inboards, outboards, stern drives and
diesels — or hydraulically steered sailboats. This robust unit gives powerboat
users an easy-to-use autopilot system to rely upon for navigation. With its
solid-state 9-axis AHRS, Reactor 40 mounts nearly anywhere, in any orientation
and requires minimal commissioning. Our patented Shadow Drive technology gives
boaters the security of knowing they maintain control, even when relying upon
Solid-state 9-axis AHRS
With its advanced solid-state 9-axis solid-state 9-axis AHRS, you can mount
Reactor 40 nearly anywhere, in any orientation. In addition, this new system
greatly minimizes heading error, course deviation, rudder movement and power
consumption while providing a comfortable ride for all on board.
Reacts to Conditions
This amazing autopilot actually reacts to the sea to hold your course. Even
when the boat is pitching and rolling, you can remain confident that the
Reactor 40 autopilot will keep you on your desired course.
Minimal Commissioning and Calibration
All autopilots require commissioning and calibration — all of them. We know
you just want to get on the water, so we made this process as fast and easy as
possible. That’s the power of simple.
Full Integration with Garmin Chartplotters
Combined with a compatible Garmin networked chartplotter, you can have full
control of Reactor 40 from wherever you are on the boat. In addition to
holding its course in virtually all weather and wind conditions, the system
can smoothly perform a variety of preprogrammed trolling and search
procedures. Plus, with a compatible Garmin networked chartplotter and BlueChart®
g2 Vision® charts (sold separately), you gain optional features such as Auto
Guidance¹, which automatically steers GPS paths.
Stay in Control with Shadow Drive Technology
The Reactor 40 autopilot features patented Shadow Drive technology. This gives
you the security of knowing you maintain control, even when the autopilot is
engaged. The Shadow Drive system automatically disengages the autopilot if the
helm is turned, giving you the freedom to maneuver the boat. The autopilot
automatically re-engages when you hold a steady course.
Connect to Networked Devices
Reactor 40 is operated using up to 3 GHC™ helm control units. GHC communicates
with the autopilot system via your NMEA 2000® network, so autopilot heading
data can be shared easily with other devices. This enables MARPA and chart
overlay when connected to a Garmin chartplotter. An optional handheld wireless
remote control is also available; however, for the highest level of
convenience, control GHC using a compatible quatix® 3 or quatix
5 marine multisport smartwatch.
