Reactor™ 40 Steer-By-Wire Standard Corepack without GHC™ 20

The Most Responsive Autopilot System on the Water

  • Solid-state 9-axis Attitude Heading Reference System (AHRS)
  • Minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride
  • Minimal commissioning and calibration

Reactor 40 for steer-by-wire provides robust autopilot capabilities for SeaStar Optimus systems, Yanmar Marine ZT 370 stern drive electronic power steering systems and ZF 2800 Pod drives.

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.

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 minimizes 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 & 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 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.

Good shirt, but not perfect
I have bought three of these shirts. They fit well, look good, good value for the price, don't wrinkle easily. The fabric is VERY heavy and does not breathe well, so they are better suited for winter than summer wear. The placket tends to bunch up when you're seated, so wearing an undershirt can be helpful. The only thing I'd change about it is the fastener on top would be better as a standard button, or be fastened closer to the shirt. When worn buttoned-up, there's enough room between the two halves of the shirt that one side folds down and there's an unnecessary collar gap that doesn't look great. When worn unbuttoned, the fastener dangles (which again, doesn't look great). The shirt also doesn't have collar stays, so the collar can roll up.

Favorite Shirt
Color: All White, Size: X-Large
Love these shirts! I like how sleek they look with hidden buttons and no pockets. I plan to order other colors. Great for travel because they wrinkle very little. Comfortable and true to size.

Great Dress Shirt
Color: All White, Size: X-Large
Absolutely love this shirt! It's super stretchy and breathable—perfect for staying comfortable all day. The fit is flattering, and the material feels high-quality yet lightweight. I was especially impressed that the bright white color stayed vibrant even after washing. Highly recommend!
