RAI
A stand alone Rudder Angle Indicator system is a complete single station RAI system. This is typically used on vessels that do not have a built-in RAI with their Autopilot or in cases where a separate RAI system is required (such as Hydraulic Full Follow-up steering systems).
A rudder angle indicator displays the actual position of a boat’s rudder. If the boat experiences a power failure, so does the indicator. A stand alone system provides continued operation in case of power loss. A complete Stand Alone RAI system includes the rudder follower unit and linkage assembly, and RAI distribution box, one 76-mm rudder angle indicator meter and 50′ of cable.
