Example 240 shows a typical twin rudder - twin wheel transmission solution (Allures 45). Two fully independent steering system each drive one rudder and a separate lever set links both rudders. The gearboxes are mounted below the cockpit floor and please note the integrated drive unit on the starboard gearbox. This system is more expensive in purchase price than a cable system, but much more reliable, much easier to install and much more robust.

Example 241 shows a variation on example 240 (Allures 51). The reduction boxes are now mounted right down into the hull driving both rudders independently.

Example 243 shows a solution where both steering positions are first joined together and drive one reduction gearbox, which then drives both rudders. This solution is as direct and robust as above solutions, but misses the redundancy of two independent steering systems.

Example 244 shows a variation on example 240. The reduction boxes are now mounted above deck in the bottom of the cockpit benches. The output levers are just below deck level and the rudder linkage is done at the gearboxes and not at the rudders. This creates a very compact solution. Note the autopilot drive unit on the starboard reduction box, above deck in the cockpit bench.

Example 245 shows a chain driven transmission system. This solution saves the steering bevel box, two universal joints and a torque tube. It's also ideal when the space in the steering pedestal head is limited and there is no room for the larger steering bevel head. Please note the autopilot drive unit driving the port steering shaft.

Example 246 shows a twin WP800 pedestal transmission steering as used on the Guardian 60. The first part of the steering system (inside the WP800 pedestal) is chain driven. Please note the autopilot drive integration on the port reduction gearbox.
