SmartDrive™
The Reactor 40 sail corepack with SmartDrive actuator is the first sailboat autopilot to use a brushless linear actuator with built-in ECU. Get precise rudder awareness with minimal mechanical wear.
FITS YOUR VESSEL
The brushless linear actuator is suitable for a wide range of sailboats and catamarans (up to 45 feet/maximum 33,000 lbs displacement).
SMARTDRIVE ACTUATOR
This product is the first sailboat autopilot to use a brushless DC motor with a built-in ECU to provide superior performance and simplified installation.
SOLID-STATE 9-AXIS AHRS
You can mount the Reactor 40 CCU nearly anywhere, in any orientation.
WATER CONDITION REACTIONS
This autopilot reacts to sea conditions so you can sail with confidence — when pitching or rolling.
