EX31 Concept & Performance

It is time to get ready for the excitement of acceleration and comfort.

• You can rest assured that the engine will start at once even in a cold winter weather. Also, the engine maintains its pick performance for much longer even when used continuously at varying low and high speeds.
• While maintaining low fuel consumption, a diesel engine uses the cheaper diesel oil, significantly reducing fuel costs to nearly 1/3 of that in case of gasoline.
• A diesel engine can maximize the compression ratio and thermal efficiency, and thus minimizing the fuel consumption, which is maintained even when idling.
• Compared to a gasoline engine, a diesel engine demonstrates a smooth and stable performance and power output even during a long-distance sailing. It also ensures a comfortable feeling of control over the boat and maneuvering.
• A diesel engine does not require an electric ignition system that is sensitive to water and salt. Therefore, a diesel engines are highly reliable with only a few failures and excellent startability.
• A power source for lighting equipment can be provided by adding a generator to the engine.

A uniaxial inboard direct drive system that ensures a sense of stability.

A well-balanced hull design with the center of gravity near the midship; The wing-shaped rudder providing superior steering and course retention.

A transom that assists and improves the steering when reversing

The lowered shape of the transom stern ensures that the water resistance is released downwards even when there is a follow-up wave, thus ensuring smooth turning and reversing.

High-performance V-shaped hull with improved course stability and wave resistance.

The flat sliding surface reduces resistance at high speeds and makes a great start. The V-shaped hull on the bow cushions the punching impact and creates a significant power against cross currents.

Double chine that enhances stillness and stability.

It provides excellent lateral stability and loading when anchored, as well as ensuring ideal high-speed sailing by reducing the contact area with water.

A low profile that maximizes the comfortable of the ride.

The low-line design that suppresses the height of the bridge from the sea surface reduces cross flow due to wind. In addition, the overall design has a low center of gravity, achieving comfortable stability even when driving at high speeds.

Design that makes full use of original know-how and cutting-edge technology.

For optimization of the hull design, we make full use of the latest technology combing 3D-CAD (3D computer-aided designing tool) and NC (numerical control) processing tools, to ensure highly accurate structuration and modeling of the molds. Furthermore, strict performance tests makes sure that nothing but only highly accurate body segment is produced.
