Autopilots
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.
