8.2 INTERCEPTORS SYSTEM

To improve the yacht’s performance during navigation, they have been installed on the transom two electric interceptor, one on the starboard and one on the port side for variation both longitudinal and transverse alignment.

The controls are integrated into the main engines throttle with ATCS (automatic trim control system).

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 comfortable 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.

A signal sent from the helm station to the electronic control unit located in the engine room activates the interceptor drive motor.
The motor rotates in the chosen direction and determines the interceptor inclination.
Pressing the button on the other position determines the opposite movement of the motor. Each button controls the movement of a interceptor.
The monitoring system provides a reading of the trim adjust inclination, measured by means of a position transducer fitted to each interceptor.
Some suggestions will be useful in familiarizing yourself with the interceptors:

• After the hull has moved to the glide position, adjust the position of the interceptors to find the angle most favourable to navigation;
• At high speed, it is advisable not to operate the interceptors simultaneously, one up and the other down, but to perform the operations separately 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 on her beam ends;
• 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, running at high speed, requires special attention and it is normally not recommended.

CAUTION

The interceptors, as well as transmission systems, can suddenly change the yacht direction if operated too rapidly or with high angles of incidence, especially with increasing yacht speed and during manoeuvres (as they are usually sized and optimized for intermediate speed).

WARNING

As is good practice on a yacht, always make sure that passengers are seated before performing large adjustment manoeuvres on the interceptors, especially if you are navigating at high speed.

CAUTION

Periodically clean Interceptor to remove any corrosion that may affect their efficiency.
