Garmin B Compact Drive Unit f/GHP™ 12 Autopilot System

The Garmin B Compact Drive Unit for GHP 12 Autopilot System is a Class B marine steering actuator engineered for sailboats requiring precision autopilot control. This compact drive unit integrates directly with the GHP 12 autopilot system to deliver responsive, hands-free steering management, allowing skippers to maintain course without constant manual helm input. Designed specifically for sailboats with displacement up to 48,400 lbs, this drive unit combines reliable steering actuation with the compact footprint essential on modern sailing vessels where space is at a premium.

The Class B designation indicates this unit is optimized for smaller to mid-range sailboats, providing smooth, proportional steering response across varying sea states and wind conditions. At 23.8 lbs with dimensions of 11 x 7 x 32 inches, the compact drive unit installs below deck or in locker spaces without requiring extensive structural modifications. Its integration with Garmin's GHP 12 system means access to waypoint navigation, autopilot mode switching, and real-time course correction through compatible Garmin chartplotters and displays—critical capabilities for both day-sailing and offshore passages.

This autopilot component serves cruising sailors, race competitors, and fishing crews who rely on consistent steering control during long passages, charter operations, or when crew attention must focus on other deck tasks. Weekend boaters benefit from the reduced physical strain on extended day sails, while serious offshore anglers appreciate the precision tracking needed to maintain fishing marks or transit to distant grounds. If your sailboat already operates a GHP 12 autopilot system or you're upgrading from an older drive unit, Garmin's B Compact Drive Unit delivers proven marine steering reliability backed by Garmin's marine-grade engineering standards.
