5.5 ENGINE DRIVE

Although this yacht is very efficient, due particularly to very sensitive rudders, which allow immediate reaction to controls, its use, considering its high performance and big dimensions, requires a careful and responsible steering.

CAUTION

Even if the automatic pilot controls the route, navigation must be supervised in any case. Adjust the speed of the yacht and the interceptors’ position according to the conditions of the sea and the prevalent direction of the waves; in this way, the structure of the yacht is not submitted to useless stress and the passengers can enjoy more comfort during navigation.

The excellent quality of the engines allows keeping the maximum speed ratio for a long time, without problems.

In order to achieve the best compromise between comfort and speed, while minimizing fuel consumption, it is recommended to keep the engine operating speed in the range between 1500 and 2000 rpm.

CAUTION

During navigation, the rear sliding door should normally be kept closed, in order to prevent any exhaust gas and water splash from entering deck compartments. This will improve comfort for the passengers and silence inside the compartments.

Avoid keeping the engines at idle speed for long time, they could get overheated.

Avoid harsh accelerations or decelerations and consequently excessive stress for the engines.

Keep the engines at idle run for some minutes before stopping them, so that they can gradually cool down.

Once the yacht has reached the cruise speed, engine control devices should settle on steady values. If the instruments show contrasting or abnormal indications during continuous running, check the systems and the equipment.

Observing the following guidelines will improve comfort, minimize noise inside the yacht, avoid damage and assist in the proper operation of the yacht.

• Do not run the engines at idle longer than necessary.
  Avoid sudden accelerations and decelerations, which create stress on engine turbochargers.
• Run at idle for a few minutes before shutting down the engines, to allow a gradual cool-down.
• Once the yacht is at cruising speed, the engine instrumentation readings should remain steady. However, if, during normal operating conditions, the engine gauges show abnormal or contradicting values, investigate for possible systems and/or equipment problems or failures (stop the engines).
• Monitor the control panel gauges and system condition alerts frequently.
• Once in open waters and well clear of other boats, increase the engine rpm gradually, until the desired speed is reached. Adjust the interceptors’ position for the best performance.
• Adjust the speed to accommodate sea conditions.
• Check the engine exhausts. Very black smoke means in particular dirty filters or unburned fuel, due to improper calibration of injection pumps or injectors. Very white smoke may mean presence of water in the fuel. Bluish smoke may mean abnormal oil combustion.
• In case of abnormal vibration, reduce speed and run at slow rpm until the cause of the vibration is determined. If the vibration is severe, take the engines out of gear. It may be necessary to check the propeller condition. It may also be necessary to have a specialized technician check the alignment of the propeller shafts.
• Perform a visual inspection of the bilges periodically.

Be aware of the fuel supply in relation to the distance you plan to cover.

WARNING

While the yacht is underway, all persons on board must be seated in the designated seating areas in order to prevent injury due to falls caused by sudden yacht movements in active wake areas or in the event of sudden changes in yacht speed or during manoeuvring.
