The reduction of mechanical noise from traditional internal combustion engines significantly changes the experience at sea.

But the value of a low noise level is not limited to passenger comfort.

Silence should also be evaluated from an engineering, operating environment and environmental impact perspective.

Source of mechanical noise

In internal combustion engines, the combustion process, moving mechanical parts, exhaust system and various vibration sources create constant noise.

This sound can be carried to different parts of the body.

Since there is no combustion in electric motors, their operating characteristics are fundamentally different.

Thanks to lower mechanical vibration, a calmer environment can be created inside the boat.

Passenger experience

Especially in daily use boats, the silence of the electric propulsion system can completely change the character of the product.

Hearing more natural sounds of the environment instead of engine sounds at sea becomes an important part of the user experience.

In electric dayboats such as the Volster 535 E, this is not only a technical advantage, but also a component of the perception of luxury and comfort.

In terms of crew

In commercial marine vessels, the captain and crew may work in the same environment for hours during the day.

Reducing continuous engine noise contributes to the quality of the work area.

It may also become easier for the captain to communicate with passengers or other crew members.

vibration

Along with noise, vibration is also an important factor.

Vibration caused by the engine and transmission systems may affect comfort in long-term use.

When correct system integration is made in electric propulsion systems, the vibration character can be significantly reduced.

For this reason, in electric boat design, the integration of the engine into the hull is as important as the choice of engine.

Another dimension of sustainability

Sustainable shipping is often discussed solely in terms of carbon emissions.

However, the environmental impact of modern maritime transportation is much wider.

Elements such as energy consumption, material use, maintenance needs and noise are also parts of the holistic approach.

In Navarc's electric marine vehicle approach, silent operation is therefore not considered a secondary feature, but one of the core values of the product.
