A steering system on any boat can become quite complex!

We can design a steering system from A to Z. We calculate the torque, the wind effects on the ship and the hydraulic system.


The helm pump is located right behind the wheel and it removes any friction on the bar, helping you turn easily. Often hydraulic based, we have to know certain informations about the boat and the hydraulic system to choose the right one.

  • Model : Steel or bronze
  • Power : 40 to 650cc
  • Non-load reaction
  • Hydraulic or electric

The Jog Lever is used to replace or help the wheel. The operator can move the boat by a simple left-right motion with the lever. But the lever doesn't move in the same direction the rudder does, it slightly moves the boat in the direction the operator wants it to go.

  • Waterproof
  • Easy to install
  • Spring return
  • 1 or 2 speed

Propulseur d'étrave


Models : in aluminium or bronze

Usage : The goal of this valve is to protect from hydraulic shocks or over pressurization, that can damage the steering limp or rudder. This valve also serves as a bypass valve if there is a system malfunction.

The drawbar is quite important : it converts linear motion on a cylinder into rotary motion of the rudder stock. It happens to calculate it well to withstand all the blows, mechanical and hydraulic forces which are imposed on it.

Cylinders are all built in bronze or stainless steel, so they can't exceed pressures of 2000 psi. So these work perfectly for conventional steering systems that are around 1000 to 1500 psi. Their bronze conception makes them extremely resistant to marine conditions, which means less rust, repair or change of parts. Their price might surprise you, in a good way!

Again, let us help you find the best equipment for your needs and give us a call!

Vitals provides advanced warning of potential equipment failures with a range of intelligent alarms that alert you of potential problems before they become catastrophic. The specific advantage of this centralized monitoring and alarm system is that it can be easily configured to suit your specific boat. Whether it's the temperature of a bearing or the cycle times of your bilge pumps, Vitals will monitor your boat's systems and alert you when a monitored piece of equipment is outside of its operating parameters.

The rudder feedback unit (RFU 7168) is designed to be mechanically connected to the rudder stock, to feed back rudder angle position data to autopilots, rudder angle indicators and full tracking control systems. It is constructed of bronze and stainless steel for marine environments and durability.


Also available, we have rudder clamps, to ease the connexion between the feedback unit and the rudder stock.
