Despite the yacht’s efficiency and high performance, the use of this yacht requires careful and responsible conduct.
The minimum gliding speed is influenced by the displacement, the distribution of the weights on board, the position of the interceptors and the conditions of the sea. An excellent compromise between transfer speed, comfort and consumption is obtainable with about 1500/2000 rpm less than the maximum allowable revolutions.
Do not keep the propulsion engines at idle for a long time; in this way they do not become “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 RIVA After Sales & Service Department.
CAUTIONSet 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 does not undergo to useless stresses and the passengers can enjoy more comfort during navigation.
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.
DANGERIt 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 persons on board and for the safety of the yacht itself, however when the engine is running it should not run higher than 1000 rpm.
WARNINGAvoid prolonged use of engines at low speeds to avoid overheating of the exhaust pipes due to reduced cooling water circulation.
