When a direct link from the rudder to the pedestal via a rack and pinion system isn't possible, the best, most direct and strong mechanical steering system to go for is the Jefa transmission steering system. The transmission steering is based on the same principals as the rack and pinion system; the rotation of the wheel is transferred to a push pull movement via a gearbox and levers. The difference with the rack and pinion system is that the distance from the wheel to the rudder shaft can be much bigger and the routing more complex. Via torque tubes, universal joints, and bevel gearboxes, the rotating movement is transmitted to the reduction gearbox next to the rudder shaft. The reduction gearbox transfers the rotating movement into a push and pull movement on the tiller lever. As all rotating parts are running in roller bearings, and the system can be easily back driven by the rudder, the result is a steering system which can be far away from the rudder, but with the same precision and feel as a tiller steered boat.
