Jefa Steering produces a
revolutionary traveller system for twin wheel, twin rudder sailing
yachts which has no backlash and it is a huge space saver. The Jefa
traveller is free off backlash and specially made to attach cables and
draglinks.
Jefa Steering has developed an 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 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 JEFA steering traveller now allows a light
running, backlash free connection between both rudders.

What makes the Jefa steering traveller unique and an absolute
innovation?
The for centuries used bulky steering quadrants can now be
replaced by the new compact steering traveller.
Revolutionary, innovative traveller system to link twin rudders
on twin wheel boats.
Huge space saver!
Unique system to transfer cable movement into rudder movement.
Free of any backlash or play.
No loss of any helm feel on the steering wheel.
Special usage for cross-bow connections in catamarans.
Maintenance free due to the use of anodized marine grade
aluminum.
Large weight save compared to quadrant solutions.
Price saving compared to the current quadrant solutions.
To safe space and prevent damage, some production boats are
delivered without the rudders mounted. The Jefa Steering traveller
allows the full steering system to be installed and just the
draglinks to be mounted when the rudders are mounted in the hull.
