JEFA WP850 CABLE STEERING PEDESTAL
The WP850 pedestal.

 

 The WP850 "A-frame" pedestal solution is Jefa's answer to the demand for a strong, light and affordable pedestal for the growing number of cruiser/racers which require a modern steering solution. The pedestal is completely made of high strength aluminium 6082. To protect the pedestal against the tough environment it’s alochromed (chromate conversion coating) and after that powder coated resulting in an long lasting finish. This build method results in a relatively low weight (7.5 Kgs) and a very strong and stiff construction. Due to a very flexible build method, the pedestal height is variable.
Brake spinner is not included and should be ordered separately.

Jefa 850 series steering pedestal variations
  • Jefa has a wide range of steering wheels which fit on all our pedestals and steerers.
  • On request the standard BS25 bulkhead steerer on WP850 can be change to a BS50 as a possibility to get the wheel 34 mm closer to the pedestal.
  • Jefa's integrated steering disengagement unit can be installed on WP850 as an easy, safe and fully invisible unit to disengage the steering wheel while sailing.
  • A GUA800-R guardrail can be installed on the pedestal. The robust 32 mm diameter stainless steel 316 guardrail is firmly attached with a bracket to the pedestal offering a strong support when moving around in the cockpit.
  • With a GUA800E-R forward bend extended guardrail (called kick-back guardrail) it is possible to mount an instrument pod for the mounting of instruments, buttons and joysticks.
The following illustrations show the most common combinations.
Jefa 100 series guardrail feet

The Jefa type 100 guardrail feet are unique in the world as they not only secure the guardrail firmly to the cockpit floor, but they also provide a watertight solution when cables have to go through the cockpit floor. The only part visible from the outside is a 5 mm high, 40 mm diameter black ring as the top of the guardrail foot is inserted into the stainless steel tube. A 3 mm O-ring makes sure no water will enter from outside. Jefa steering produces 3 types of guardrail feet. Type 1 is supplied when no penetration to the cockpit floor is required for engine control or instrument cables. Type 2 is supplied when engine control or instrument cables have to go through the cockpit floor with a maximum thickness off 45 mm. Type 3 is supplied when engine control or instrument cables have to go through the cockpit floor with a maximum thickness off 95 mm.

The steering shaft has 2 high efficiency 25 mm ball bearings, which are double sealed and pre-lubricated for a long and maintenance free life. The lip seal at the front is the especially developed Jefa PUR seal, which contains no metal parts for a life long problem free usage.
The pedestal can be equipped with multiple sprockets to match the turns starboard to port as specified. Please look at the table for choosing the the sprocket size in relation to the quadrant radius.
