Speed and Range
The yacht on sea trials ran at a maximum speed of 32 knots and a cruising speed of 26 knots. The cruising speed corresponds to the 75% of the maximum power. The yacht is estimated to have a range at cruising speed of 26 knots of 540 nm, on the basis of 31000 lt fuel. Total fuel consumption will be determined by the MTU monitoring system and considering the fuel consumption to power the electrical equipment in use in day navigation in accordance with the electrical load schedule.
 When in hybrid mode, the yacht cruises at low speed of 8 knots with two main engines OFF; the two waterjets are then powered by the two electric motors connected to the gearbox PTI. The two diesel generators supply power to both the general switchboard.
 
Hull
The all-composite hull of the vessel is of Fibre Reinforced Plastic (FRP) construction producing a single, strong and durable structure. The exclusive use of the composite materials in the manufacture of the hull offers benefits in terms of improved thermal and noise insulation, resistance to corrosion, strength and less maintenance.

The Composite construction provides an excellent balance in terms of weight savings and vessel's performance achieved through the use of state of the art construction techniques with proven success. Materials used for the construction of the hull have been fully approved by the Classification Society.
 
Superstructure
The yacht's superstructure are also constructed in Fibre Reinforced Plastics with PVC cores and local reinforcements. The result is a single, strong, lightweight and durable structure. Exclusive use of composite materials in the manufacture of the deck and superstructure offers the benefits of an improved thermal and noise insulation, easy maintenance and reduced weight.
 
General Painting
Hull topside and superstructure are meticulously faired and finished in a metallic light grey paint. 
Bands in the way of window lines are painted black.
 
Propulsion and Generation
General
The main propulsion system consists of two marine diesel engines driving two water-jets through reduction gear-boxes.
The two lateral gearboxes drive a variable displacement hydraulic pump. Those provide oil pressure to operate the jet steering system.
The main ship electrical generation power system consists of two variable speed diesel generators and one shore connection.
Main engines and generators are resilient mounted to minimize noise and vibration.
The yacht is also equipped with a hybrid propulsion system, EcoProp by Siemens®, which allows it to cruise at a safe low speed of 8 Knots with the two jets powered by two electric motors connected to the gearbox PTI.

Electronics / Entertainment System
The 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 is built under the survey of and in full accordance with the R.I.N.A Rules for the Classification of Charter Yacht including additional rules applicable to pleasure vessels for the assignment of the MCA LY2 Short Range Yacht compliance certificate and all amendments and notices issued up to the date of signing the Vessel.
