Cobra™ Installation Guidelines
L1 Standard pedestal height

L1 = 710mm/28". Range from 178mm/7" to 915mm/36".
L2 Standard under deck dimension
L2 = 102mm/4". The minimum dimension is governed only by the thickness of the cockpit sole. Where an extended L2 under
deck is required, it may be necessary to also add a torque snubber plate.
L3 The distance between the centre of pedestal and the rudder stock.

L3 can vary between 120mm /5" – 2000mm/79". Draglinks are made to specifi cation and are adjustable by 20mm/0.78" upon
installation. The draglink should not exceed an angle of 5° from the horizontal.

A standard Cobra™ installation can accommodate a rudder rake up to a maximum of 30°. However this does depend on the
boat size and type and the length of L3. If the angle exceeds 20°, please consult our Lewmar representative. As standard, all
levers are mounted to the starboard side and the pedestal is mounted forward of the rudder stock.

Frequently the space directly below This illustrates the use of a wheel
the cockpit fl oor is limited and this trough and shortened height
special bearing arrangement reduces pedestal, particularly common on
the Cobra™ Racing installations where
intrusion into the accommodation. large wheels are fi tted.

Besides giving more mechanical
purchase, the large diameter wheel
enables the helmsman to sit out
and still reach the helm. Please
note that the use of a torque
snubber plate may be necessary
to counteract the extra pitching
L1 movement caused by the large

L2 dimensions (greater than
152mm/6").
