Example 230 shows a twin rudder - twin open wire system. The system is fully
redundant as two identical systems drive each rudder which are linked by a
draglink.

Example 231 shows a twin rudder - twin open wire system (Allures
51). The system is fully
redundant as two identical systems drive each rudder which are linked by a
draglink. Due to the constant high cable tension, both rudderstocks are pulled
hard in the bearings. It's vital for a low friction system to make sure all
bearings (rudder, sheaves steerer) are ball or roller bearings. Gliding bearings
are absolutely not advisable. Please note the independent autopilot drive unit
type Direct Drive type 1.
