8.4.1 Engine drive

Despite the efficiency and the high performances of the yacht, and in particular the sensitivity to rudder motion, which allow an immediate response to the controls, the use of this yacht requires a careful and responsible behaviour.
In the passage between displacement and gliding navigation there is a critical phase to be carried out as quickly as possible, as it is characterized by high consumption and more vibrations; it also causes a very deep wake.
The minimum gliding speed is influenced by the displacement, the distribution of the weights on board, the position of the interceptors and the sea conditions. The excellent choice and quality of the engines allows keeping high speeds for a long time with no consequences.
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.
Do not keep the propulsion engines at idle run for a long period of time; this to prevent them from getting “dirty” or overheated.
Avoid harsh accelerations or decelerations to avoid excessive stresses for the engine turbines.
When the yacht reaches the cruising speed, the engine check instruments should set to constant values.
If the instruments show contrasting or abnormal indications during continuous run, check for failures of the systems or of the equipment and contact Assistance Service.

CAUTION

Even if the automatic pilot controls the route, navigation must be supervised in any case.

CAUTION

During navigation, keep rear window closed to avoid the introduction of exhaust gases and water splashes into the main deck compartments, under special conditions of wind direction and force.
This will improve comfort for the passengers and silence inside the compartments.

CAUTION

The speed of the yacht must be controlled, together with the position of the interceptor, according to the sea conditions and the prevailing wave direction, so as not to subject the structure of the yacht to avoidable stress and assure the occupants’ comfort when underway.

DANGER

It is absolutely forbidden to perform reverse run with one of the two engines stopped. This operation is allowed only in case of life danger for the people on board and for the safety of the yacht itself, however when the engine is running it should not run higher than 1000 rpm.

WARNING

Avoid prolonged use of low speed engines to avoid overheating of the exhaust ducts due to reduced circulation of cooling water.
