Garmin's Most Responsive Autopilot System on the Water

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimises heading error course deviation rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration
  • Supports heading hold wind hold step turns and tack/jibe modes

With a complete package designed for powerboats and sailing boats 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. If you don't see a compatible Reactor 40 you'll find the Reactor 40 mechanical/retrofit/solenoid is compatible with a wide variety of steering systems whether hydraulic cable drive mechanical and solenoid. Just pair GRF 10 with your drive system already on board.

The Reactor 40 mechanical/retrofit/solenoid autopilot corepack is ideal for sailboats and powerboats with direct or cable-actuated steering systems. This Reactor 40 below-deck autopilot system gives captains that extra set of hands they need so you can safely attend to your sails lines winches and radios without worry. With its solid-state 9-axis AHRS Reactor 40 mounts anywhere in any orientation and requires minimal commissioning.

Solid-state 9-axis AHRS
With its advanced solid-state 9-axis AHRS you can mount Reactor 40 nearly anywhere in any orientation. In addition this new system greatly minimises heading error course deviation rudder movement and power consumption while providing a comfortable ride for all on board.

Reacts to Sea 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 our compatible 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 pre-programmed 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 Guidance which automatically steers GPS paths.

Stay in Control with Shadow Drive Technology
On hydraulic installations the Reactor 40 mechanical/retrofit/solenoid autopilot corepack can add optional 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 manoeuvre the boat. The autopilot automatically re-engages when you hold a steady course.

Choose from 3 Class Drives
Reactor 40 is available with 3 linear drives (sold separately) capable of driving many different steering systems on most midsize to large vessels (depending on the particular installation). All Garmin linear drives include built in rudder feedback sensing.

  • Class A Drive Unit — up to 12.9 tons of displacement
  • Class B Compact Drive Unit — up to 22 tons of displacement
  • Class B Drive Unit — up to 35.8 tons of displacement

Add Even More Peace of Mind

Add an optional GRF 10 rudder feedback sensor and you can further enhance the performance of your Reactor 40 autopilot.

They are using different/cheaper shredded foam then they were 1 year ago
Color: Memory Pillow, Size: Standard, Color: Memory Pillow, Size: Standard
The shredded foam used last year was really nice and soft and even firm to a point where your head is supported perfectly while you sleep. now the 2 extra pillows I received this weekend have completely different shredded foam which seems to be cheaper. Also when you unzip the pillow cover and get to the part where you can unzip the other cover where the foam is no longer is there. so they are using cheaper shredded foam and a cheaper cover to where the foam is and you can no longer unzip the second cover to see the foam. but I can easily tell that they are using different and cheaper foam which isn't true memory foam. their new blend is too fluffy and the pillows are floppy and too soft. the old ones i bought 1 year ago are heavy pillows that are true memory foam which your head molds into perfectly and are amazing. these new ones they are making aren't worth it. In one picture you can see the cover with different colored cheap foam and the other picture with the green and white thick premium quality shredded memory foam. The other pictures show how the old ones are thick and firm and moldable for you head and the other 2 are floppy because they use cheaper shredded foam. They need to use the shredded foam they used last year! it was really good! Now they are not true memory foam pillows anymore due to changing from premium shredded foam to cheap shredded foam.
