The GHP 12 brings Garmin’s full-featured marine autopilot technology to the sailing community. This second-generation autopilot is designed for 20- to 70-foot sailboats with linear-actuated steering systems.

Enjoy Simplified Sailing

Using the GHP 12 sailboat autopilot system is like having an extra set of hands aboard your vessel. When interfaced with Garmin's GWS 10 or compatible wind sensor, GPS and network electronics (all sold separately), the GHP 12 can support heading hold, wind hold, step turns, tack/jibe and much more. This allows you to safely attend to your sails, lines, winches and radios without worry.

Connect to Networked Devices

The GHP 12 is accessed through the GHC™ 10 helm control unit, which is fully NMEA 2000® certified. In addition to easy installation, NMEA 2000 compatibility allows you to share autopilot heading data with other devices on your network, including Garmin chartplotters that can provide GPS-enabled route guidance. The GHP 12 supports both linear actuated steering systems on sailboats on a single system. For sailboat applications there are two linear drives available from Garmin capable of driving many different steering systems to fit almost any midsize to large sailboat (depending on the particular installation):

  • Class A Drive Unit - For sailboats with up to 28,500 lbs of displacement.
  • Class B Drive Unit - For larger sailboats with up to 79,000 lbs of displacement.
