6 Spoke Folding Lewmar Wheel, Lewmar pedestal, Silva Compass.

Lewmar Cobra System. Beautifully engineered Lewmar (Stainless Steel) folding wheel, pedestal, and rack & pinion mechanics - designed for sensitive steering in aft cockpit yachts up to 45ft. Silva Compass.

 

The principle of the Cobra steering system is based on the precision gearcut circular rack and pinion in the head of the pedestal, providing the necessary mechanical advantage. The quadrant gear is connected to a stainless steel downtube, at the base of which is an output lever. This connects to a similar lever, mounted on the rudder stock, via a fully adjustable draglink.

All shaft work is carried through high efficiency sealed ball races and the mesh of gears is controlled via shims under the input, eliminating any lost motion. The input socket also houses a powerful and progressive friction brake for dampening the wheel, when at anchor, for example.
