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.

• A linear drive unit connects to the rudder stock via an independent tiller arm. Accessory ﬁttings from your steering system manufacturer may be required.

• An authorised Raymarine dealer is best suited for installing a linear drive system.

• Must be able to back-drive steering system from the rudder.

STEERING SYSTEMS

When selecting an autopilot drive unit for a mechanical steering

system, the vessel displacement is the determining factor for selecting

the correct drive.

When determining your vessel displacement, always add

20% to the displacement of your vessel to account for

the added weight of fuel, gear, provisions and people.

Raymarine SmartPilot drive units for mechanical steering systems are

available in linear, hydraulic linear and rotary conﬁgurations.
