EX40Ⅱ Concept & Performance
With high power output and low fuel consumption, EX40II demonstrates a high-speed performance while minimizing vibrations.
Direct injection diesel engine
This is a high-performance engine with excellent durability, acceleration and reliability. The engine is both stable and highly fuel-efficient at high as well as low speeds, and the large 800-L fuel tank allows navigations for an extended time. In addition, the anti-vibration support reduces vibrations and noises.
There is a option of the 6CXBS-GT engine allowing high-speed driving of 35 knots*.
- ※Tested under standard light load conditions.
6LY2-WST 279kW / 3200min-1
(380PS/3200rpm)
6CXBS-GT 363kW / 2700min-1
(495PS/2700rpm)
Advantages of diesel engine
- You can rest assured that the engine will start at once even iin a cold winter weather. Also, the engine maintains its pick performance for much longer even when used continuously at varying low and high-speed ranges.
- A diesel engine can maximize the compression ratio and thermal efficiency, and thus minimizing the fuel consumption, which is maintained even during idling.
- Compared to a gasoline engine, a diesel engine demonstrates a smooth and stable performance and output even during a long-distance sailing. It also ensures a comfortable feeling of control and maneuvering in the driver.
- 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 connecting a generator to the engine.
Uniaxial inboard direct drive system
The uniaxial inboard direct drive system helps to achieve a stable and reliable driving.
The well-balanced hull design with the center of gravity near the midship provides stable performance with very little distortions. In addition, a large wedge-shaped rudder improves steering and, in combination with the V-shaped hull, ensures an excellent course retention.
A high-performance V-shaped hull that slices through wave resistance.
Hull
The flat sliding surface of the hull reduces resistance of water both at high speeds and at the start. The V-shaped hull on the bow cushions the punching impact and creates a strong slicing force against cross currents.
Highly stable at halt, smooth and comfortable at move.
Double chine
EX40Ⅱ has excellent lateral stability and loadability when moored, and demonstrates ideal high-speed driving by reducing the water contact area when moving. You can comfortably enjoy fishing and trolling in a stationary state.
Outstanding performance on cutting through waves and improved steering on revering.
Transom
New stern design with a lowered bottom ensures that the resistance is released downward on reversing or receiving a trailing wave, allowing a much smoother turning.
An efficient spanker that reduces cross flow.
Low profile
EX40II has a low-line design that suppresses the bridge height in better manipulation of air resistance at a high-speed. It reduces the cross-flow of the ship caused by the wind.
Development and designing process that makes full use of original know-how and cutting-edge technology.
For hull design and production, we make full use of the state-of-the-art technology such as “3D-CAD (3D computer-aided design)” and NC (numerical control) processing that enables highly accurate combination of molds with outstanding performance. Furthermore, the performance is rigorously tested to achieve perfection on every aspect.
Extra noise reduction to improve comfort
Soundproof double-layer floor structure
The multilayered floor is further enhanced by covering the hollow parts with sound absorbing material to reduce engine noise. In addition, the standard equipment of the exhaust silencer and the engine vibration isolation ensure further reduction in vibration and noise.
