9. Steering 352/353 L1 L1 L2 L2 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 specification 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 the cockpit floor is limited and this special bearing arrangement reduces the intrusion into the accommodation. This illustrates the use of a wheel trough and shortened height pedestal, particularly common on Cobra™ Racing installations where large wheels are fitted. 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 movement caused by the large L2 dimensions (greater than 152mm/6").
