4.9.1 Operating in shallow water
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.
− Check the switch panel to see if any circuit breaker has tripped due to
an electrical system fault.
− Once in open waters and well clear of other vessels, increase the
engine rpm gradually, until the desired speed is reached. Adjust the
trim tab positions for the best performance. For information on trim tab
adjustment, refer to “Trim Tabs” in the AT THE HELM chapter.
− Adjust the speed to accommodate sea conditions.
S
CAUTION
COLLISION HAZARD - Use extra caution in shallow water or where
underwater/floating objects may be present. Hitting an object at high
speed or at an acute angle can seriously injure people and damage the
yacht.
NOTICES
The best compromise in speed, to accommodate comfort and minimize
fuel consumption, is to operate the engines at 150/200 rpm under the
maximum rated rpm (also known as WOT [wide open throttle]).
NOTICES
During navigation, keep the stern tilting window closed, to prevent
engine exhaust fumes and splash water from entering the interior. As
the closure is not watertight, do not aim water directly onto the window
when washing down the yacht.
