INTRODUCTION LS Hydraulic Steering Systems Our hydraulic steering systems are perfectly adapted to outboard and inboard motor boats and pleasure, sporting, fishing and commercial applications and to monohull and multihull sailing-boats. They are easy to install, state of the art machine finished and made to resist a marine environment. You can easily select the best suited system for your boat within a range of more than 20 pumps and 30 cylinders which will provide efficiency, reliability and smoothness. Our systems carry a 2 year warranty and our range of cylinders for fishing and work...

© Manual pump ® Port circuit Tubing © Starboard circuit Tubing 4 Power pack © By-pass valve © Cylinder © Tiller arm When the helm is turned to starboard, the pump (1) sucks the oil from the port circuit (2) and pushes it back into the starboard circuit (3), thus driving the cylinder rod (6) which in turn displaces the rudder or motor. The cylinder body (6) is fixed to the boat.

SELECTION OF A HYDRAULIC STEERING SYSTEM • For boats fitted with a rudder with speed not exceeding 25 knots, the torque of the rudder or rudders is calculated according to following formula and corrections. It must be known that the torque necessary to manoeuvre a boat depends on: - the speed of the water flowing on the surface of the rudder at a certain angle, - the rudder size, - the total sweep of the rudder (and part of the boat), if the rudder stock is not perpendicular, - the compensating surface of the rudder. Torque Calculation Formula for Speed below 25 Knots C = S x [ (0.4 Lg) -...
