Notes!
1. On boats powered by outboards or stern drives it may be
difficult to install a rudder feedback unit (chapter
3.6 and
3.27). Use of the Virtual feedback algorithms in the software
may then be preferred as this requires no installation of a
rudder feedback unit (page
109). The Virtual Feedback can
be used on boats up to 40 ft.
2. In order to benefit from the virtual feedback technology your
autopilot system must be using a Simrad rate compass for
heading information.
