Garmin GHP Reactor40, CCU, SBW

The Garmin GHP Reactor 40 is Garmin's marine autopilot system for boats up to roughly 50 feet, and this listing is the Course Computer Unit (CCU) configured for a Steer-by-Wire (SBW) installation. The CCU is the central processing "brain" of the Reactor 40 autopilot — it takes heading, rudder, and rate-of-turn data and drives the vessel's steering system to hold a course, follow a route, or execute automated turns, without a mechanical link between the autopilot and the helm. SBW-specific CCUs are built to work with electronic steer-by-wire steering systems (such as SeaStar Optimus and similar drive-by-wire helms) rather than a hydraulic pump or mechanical cable-and-pulley setup, and carry their own model number in Garmin's Reactor 40 range, distinct from the hydraulic and mechanical CCU variants.

More Info

This CCU is sold as the core processing component for building or retrofitting a Reactor 40 SBW autopilot installation — it works alongside a compatible autopilot control head (such as a GHC display), a 9-axis heading sensor, and the boat's steer-by-wire steering drive to provide automated course-keeping, Shadow Drive manual override, and integration with Garmin chartplotters over the Garmin Marine Network/NMEA 2000. Because it's an SBW-specific unit, it is not interchangeable with hydraulic or mechanical Reactor 40 CCUs — the steering interface type must match the boat's actual steering hardware. As with the rest of the Reactor 40 range, commissioning (dockside setup and a sea trial calibration) is required before first use, and installation is normally carried out by a marine electronics installer given the wiring into the vessel's steering and helm systems.
