Example 150 shows twin WP800 pedestals linked via flat sheaves and
articulated sheaves are used to link to the quadrant. Please click on

holding the left button while moving, you can rotate the model.
Example 151 shows twin WP800 pedestals each driving a quadrant via a custom cross wire
idler. The system consists of two completely independent steering systems
guaranteeing full redundancy. The sheaves on the idler can be rotated to align
to the quadrant. The mounting of this system is extremely quick and simple as
the pedestals bolts have matching holes in the idlers, so with tightening 8
bolts, the complete steering system including pedestals in installed. Please

Example 151a shows twin WP800 pedestals driving a 80° quadrant via a custom wire
idler. The sheaves on the idler can be rotated to align
to the quadrant. The mounting of this system is extremely quick and simple as
the pedestals bolts have matching holes in the idlers, so with tightening 8
bolts, the complete steering system including pedestals in installed. Please

Example 152 an optimized solution for production boats. The (gray) traverse
combines all sheaves, rudder stop and autopilot drive system. The mounting of
this system is extremely quick and simple as the pedestals bolts have matching
holes in the traverse, so with tightening 8 bolts, the complete steering system
including pedestals in installed. The autopilot drive is very easy to integrate
by replacing one of the sheaves by a sprocket with a shaft and autopilot flange.
Fitting the autopilot drive is also just tightening 4 bolts. Please click on the

Example 152a a compact traverse solution for production boats. The (gray) traverse
combines all sheaves and rudder stop. As the autopilot drive is separate, the
traverse can be more compact. The mounting of
this system is extremely quick and simple as the pedestals bolts have matching
holes in the traverse, so with tightening 8 bolts, the complete steering system
including pedestals in installed. Please click on the

Example 153 is the most basic solution for a twin wheel - single rudder boot. 2
wheels, 2 BS25 steerers, 2 chain sets, 3 pieces of cable, 2 flat and 2
articulated sheaves and a quadrant.

Example 154 shows twin BS20 bulkhead steerers each driving a quadrant via a
custom cross wire
idler. The system consists of two completely independent steering systems
guaranteeing full redundancy. The sheaves on the idler can be rotated to align
to the quadrant. The mounting of this system is extremely quick and simple.

Example 155 shows a special cable solution. Due to the angle of the rudder stock
it's not possible to drive the rudder direct. This would take too much space.
The twin cable system drive the quadrant which drives the rudder via a draglink
and tiller lever.

Example 156 shows a double WP400 pedestal steering system. As two quadrants are
used, the complete system is redundant and with the autopilot drive there are
three independent systems to steer the boat (next to the forth emergency tiller
steering).

Example 157 shows a double BS25 cable steering in carbon tubes (not made by
JEFA). The custom sheaves are also made by JEFA. An ideal light and compact
steering setup for a racer.

Example 158 shows a unique space saving solution: The self-aligning quadrant.
The core of the quadrants consist of a universal joint which eliminates the
necessity for the cables to be perpendicular to the the rudder stock. Guiding
rolls position the quadrant and rudder stops can be integrated.
