9.2 INTERCEPTORS SYSTEM
The yacht is equipped with two interceptors, which can be controlled from
the control post. Each interceptor is driven by an electric motor.
They allow you to vary both the yacht’s longitudinal and transverse trim dur-
ing navigation.
Familiarisation with the use of interceptors is important, as their correct use
will improve performance and comfort.
In principle, lowering and raising the interceptors will lower and raise the
bow of the yacht respectively.
Correct positioning of the interceptors results in a stable and ideal setup
which can increase speed while reducing consumption.
In particular navigation conditions, when, due to lateral forces of the sea,
sea currents and wind, the yacht assumes an inclined attitude, to restore
normal conditions while maintaining the course, it is necessary to act on the
wheel of the rudder or with the offset use of the interceptors.
WARNING
Interceptor are normally used during cruising, both to make it more com-
fortable and to achieve better performance of the yacht, according to the
sea and navigation condition, and the yacht loading.
CAUTION
When using reverse, set the interceptors fully up otherwise they may be
damaged.
When one of the buttons on the control panel on the dashboard is pressed, the
electronic control unit located in the system room receives an electrical im-
pulse that starts the engine of the interceptor. The motor rotates in the chosen
direction and therefore determines the descent or ascent of the interceptor.
Pressing the button on the other position determines the opposite move-
ment of the motor. Each button controls the movement of a interceptor.
It is possible to visualize, through the monitoring system, the inclination of the in-
terceptors, measured by means of a position transducer placed on each of them.
Some suggestions will be useful in familiarizing yourself with the intercep-
tors:
After the hull has moved to the glide position, adjust the position of the inter-
ceptors to nd the position most favourable to navigation:
• At high speed, it is advisable not to operate the interceptors simultane-
ously, one up and the other down, but to perform the operations sepa-
rately to avoid sudden skids; instead, it is possible to manoeuvre them
simultaneously in the same direction;
• In calm seas, the best position for interceptors is to allow maximum
speed with less yacht drag;
• In rough “bow” sea, the “down” interceptors will allow you to “beat less”
and sail with more comfort even if your speed will be reduced;
• In rough seas “on the stern”, the interceptors “up” will tend to raise the
bow thus avoiding unpleasant;
• With lateral wave motion or asymmetrical lateral load, the best stability is
achieved with staggered interceptors;
• If the yacht is not in motion, place the interceptors all on.
CAUTION
The manual use of Interceptor (“trim assist” function disabled or override),
running at high speed, requires special attention and it is normally not
recommended.
