In navigation, steering precision does not rely solely on the helmsman. It also depends on the ability of the steering system to transmit a constant force, without loss or variation.
In a hydraulic system, one element directly disrupts this balance: air.
A common issue with immediate consequences
Air in the circuit is one of the most common causes of reduced steering precision.
Unlike hydraulic fluid, air is compressible.
This means that the force applied at the helm is no longer transmitted in a direct and consistent way.
The effects are quickly noticeable:
- delayed rudder response,
- inconsistent steering effort,
- a “spongy” or imprecise feel at the helm.
In certain conditions, these variations can make it more difficult to maintain course and increase fatigue for the navigator.
Understanding the source of the problem
Air can enter the system in several ways:
- during maintenance or refilling,
- through insufficiently sealed fittings,
- after intervention on the system,
- or due to low fluid levels.
Even in small quantities, its presence is enough to affect overall performance.
Simple but essential maintenance
Bleeding the system restores proper operation.
It removes trapped air and ensures direct force transmission.
Combined with regular checks (fluid level, sealing, component condition), it helps maintain:
- steering precision,
- consistent effort,
- and long-term system reliability.
Repairability as a guarantee of durability
A hydraulic system should be designed to be maintained, not replaced.
At Lecomble & Schmitt, our solutions are designed to allow:
- replacement of sealing components,
- maintenance of key elements,
- and system refurbishment without heavy intervention.
This approach ensures consistent performance, even after several seasons.
Maintaining precision over time
At sea, a reliable steering system is first and foremost a consistent one.
Removing air from the circuit, maintaining components, and relying on a system designed for durability ensures precise response in all conditions.
Because a well-maintained system is one you can rely on.
