ComNav Commander P2 system kits come with a ComNav Medium Duty Rotary Rudder
Follower Unit.
Note: P2VS kits do not include an RFU – although one may optionally be used.
The Rudder Follower Unit is used to transmit (i.e., “feed back”) the position of the boat’s
rudder to the SPU. It is mechanically coupled to whichever part of the steering system the
autopilot controls. Normally, this is the boat’s rudder; however, it can be mounted to the
servo ram rather than the rudder, if the boat has two-stage steering (where the autopilot
drives a control or servo ram).
