Autopilots
Mechanical linear drives
Our most commonly used drive types for sailing vessels. Raymarine mechanical linear drives provide powerful thrust, fast
hard-over times and quiet operation. Mounted below decks, the linear drive moves the rudder directly by pushing the
tiller arm or a rudder quadrant.
Mechanical rotary drives
The rotary drive is designed for power and sailboat systems that can be driven from the helm position through a chain
and sprocket (e.g. cable and rod steering systems). The outstanding design of the Raymarine rotary drive unit provides
smooth, powerful autopilot controlled steering with quiet operation. Use the table below to select a rotary drive suitable
for your vessel displacement.
