ELECTRONICS / ENTERTAINMENT SYSTEM
The perfect and organic integration of the systems that form the means of interface and control between the Owner, Guests and Crew represents the most important design principle of Entertainment, Communication, Security and Navigation systems.
This unified approach requires that the architecture of the main electronic system be based on network framework and cabling which are, as far as possible, shared. Integration is intended as:
§ effort to unify user interfaces;
§ TCP/IP units;
§ use of modular elements that can be assembled and connected in different ways to customize the system tailoring it to the Owner’s needs.
The fields to which this philosophy is applied are:
§ digital entertainment with top level displays, amplifiers and speakers;
§ full internet connectivity;
§ worldwide coverage for telephony and fax;
§ high level security and CCTV system;
§ home automation services (lights control, curtains control, HVAC control).
The following represent the general design rules applied for the selection of the main devices:
§ use of last-generation devices to have the most current model at time of delivery;
§ use of world wide distributed leader brands in the selection of devices in order to guarantee world-wide assistance.


CLASSIFICATION AND CERTIFICATION
The yacht, including its machinery, equipment and outfitting, will be constructed in accordance with the rules and regulations of Lloyd’s Regiter of Shipping for classification; the vessel shall meet all relevant statutory and classification requirements for a yacht of this type.
