Jefa Steering has developed a revolutionary traveller system for twin wheel, twin rudder sailing yachts which has no backlash and it is a huge space saver. The new Jefa traveller is free off backlash and specially made to attach cables and draglinks. |
Jefa Steering has developed a new innovative traveller system for modern twin wheel, twin rudder sailing yachts. Traditionally cable systems required a wire quadrant and twin rudder boats even required twin quadrants. These (in average 50 cm diameter) quadrants take up a lot of space and due to the slanted rudders required a difficult wire routing to reach them. Experiments have been conducted to use standard deck travellers to transfer the cable movement into rudder movement, but as one can’t get them without play, they distort the rudder feel every time the wheel is rotated. The new Jefa traveller is without this backlash and specially made to attach cables and draglinks. The Jefa traveller is a revolutionary steering solution for twin wheel, twin rudder boats and a huge space saver. |

The Jefa steering traveller consists of a wagon with 4 rotating
special shaped wheels which fit on a tube with tracks. The tracks
prevent the traveller from rotating around the tube so it can only move
sideways. The traveller wagon has two ø16mm pins fitted to connect
draglinks and holes with good accessibility to attach wire terminals
from the pedestals. The traveller can be used for most sizes of yachts
and the gearing ratio can be changed with the length of the tiller arm
on the rudderstock. |
Please have a look at below video showing the functioning of the JEFA steering traveller.
Jefa steering traveller for production boats: |
The Jefa steering traveller can be combined with the unique Jefa traverse solution into one part. This is an ideal solution for production boat builders as many installation hours can be avoided and no installation mistakes can be made. The traverse including the traveller is mounted as one part below deck - the pre-mounted cables are dropped in from the pedestals and attached. The draglinks are attached and ready is the complete steering installation. Clearly visible below the port pedestal is the integrated optional transmission autopilot drive unit. The installation of the autopilot drive is achieved in just a few minutes. |
Jefa steering traveller for catamarans: |
The Jefa steering traveller is also a very nice solution for cross-beam connections on catamarans which can't be made in a straight line. In the above steering system a straight draglink between the two rudders is not possible. Higher up in the beam it's possible to use a long cross bar. The new JEFA steering traveller now allows a light running, backlash free connection between both rudders. |
