 84.70 m

    Length between perpendiculars 77.20 m

  • Breadth moulded
 15.6 m

    Depth moulded to 2nd deck7.2 m

  • Design draft   4.0 m

  • Classification: ABS

  • Flag: Cayman Island (or as stipulated)

  • At draft 4 m,

  • the trial speed shall be approx. 19.5 knots at 90% MCR and 500 kW hotel

    load without sea margin.

  • Service speed approx. 17 knots at 90 % MCR with 15% sea margin and 750 kW hotel load.

  • Trial conditions: Beaufort 3 / Douglas 3

  • Endurance: 8000 nm at 17 knots 

    The Vessel will be subjected to sea trials in accordance with an appropriate sea trials program. The yacht will have a long range cruising safety margin of 10% tank capacity.
    The yacht will have enough provisions to suffice for the full cruising range, at the designated cruising speed, with a full complement of passengers and crew on board.

    The yacht shall be of welded steel hull construction and aluminum superstructure and built to North European yacht standard. The exterior of the hull shall feature styled glass, structural 'clam-shell' openings and possess a class-compliant heli-deck on the foredeck.

A comprehensive systems design integration service is provided with integrated propulsion systems and each of its constituent parts. The main power takes advantage of an advanced thermodynamic cycle, based on high compression ratio, optimized valve timing, high charge air pressure and late and fast combustion. This ensures good trade-off between fuel consumption, Nox emissions and particulates. The simple and robust design with reduced number of components ensures the system is robust and durable.

Propellers shall be Ulstein Aquamaster azimuthing pulling propeller. The azimuthing pulling propeller is a low drag, high efficient pulling thruster. It combines the advantage of the pulling propeller with the flexibility of using any type of drive to suit the customer's specific requirement. The Azipull is designed for continuous service speed up to 24 knots, whilst maintaining excellent maneuverability as no rudder is required.

The super silent tunnel thruster is designed for exceptionally low noise operation and is ideal for yachts where low noise and vibration levels are vital. It has double walls for the full tunnel length and a flexible mounted inner tunnel.

Navigation System - The Integrated Bridge concept provides a multiple workstation capability allowing switching between the automation system, radar and electronic charts and steering systems. Working with selected partners to build in navigation and communication systems, the integrated bridge uses customized touch- screens and a unified styling of controls and consoles to provide a safe, flexible operating environment. Forward-looking sonar to be provided by FarSounder.

Operator's Chair - The operator's chair is a major design aspect of the new integrated bridge system, with the focus on the optimization of the human machine interface. Using the touch-screen an array of information can be displayed, including the potentially wide range of secondary systems such as VHF communication, lighting, and management of the full propulsion system, with ultimate control of maneuvering provided by incorporating the Poscon products ranging from autopilot and joystick systems to station keeping and full capability dynamic positioning.

Power Distribution System will be part of overall integrated systems management package which provides a full power management capability for island power systems ranging in application. The system will integrate with the overall  electrical system, and as part of the wider automation system.

Stabilizers will be folding fin stabilizers that are designed for high performance roll damping whilst offering low weight and high reliability coupled with low maintenance. The PLC based control system offers state of the art technology with simple operating interfaces and extremely comprehensive maintenance and diagnostic information through touch screens.

Dynamic Positioning - The dynamic positioning (DP) systems are an extension of the Poscon independent joystick systems. The DP range is designed to meet International Maritime Organisation (IMO) specifications and requirements from the class of societies. Available range from Poscon DP and single IMO DP class 1 Systems to sophisticated redundant systems satisfying the requirements of the IMO DP Class 2 and 3.

Fairing and Paint to be of highest quality. As the finishing of yachts has become a science, 

Entertainment system provider will be a state-of-the-art, centralized media server stores hundreds of movies and thousands of CD's and connects to satellite television and radio. The audio visual system is built to exacting, exceptional standards. Users can independently select movies, music TV, Radio or internet at any time. Integrated Internet access gives fast, wireless web access and email from any System computer.

Security systems to be provided by a designated provider to level designated by Own- er. The maritime security team will be drawn from a wide variety of professional back- grounds, including master mariners, marine engineers and surveyors, international special forces; Army and Navy (including anti-terrorist units); government officials; the diplomatic service; and international coast guard units.

The yacht shall be equipped with a Jacuzzi on the Owner's Deck aft of the dimensions indicated in the G.A. Elevators will be installed as per GA. KONE elevators can be customized for this mission. Designed for shipboard use with scenic glass, minimal equipment footprint and microprocessor controls.

Modelling and Simulation


Designers rely on the use of mathematical modeling and simulations of electrical, mechanical, thermal, chemical, hydraulic, hydro-mechanical and hydro- dynamic systems to understand and predict system dynamics and control characteristics. These simulations are used to support the entire life cycle of a ship or system: from concept tradeoffs, through system optimizations and detailed design, to support sea trails, for problem resolution after deployment, and to evaluate the impact of design changes throughout vessel life.

Dynamic response analysis (DRA) Refers to the development of mathematical equations describing the dynamic behavior of the ship and system components and hen combining these equations into a unified computer simulation that predicts the transient and steady state response of the complete system. Analysts design and analyze simulation experiments to reduce technical risk by quantifying performance, designing and analyzing controls, exposing  potential performance problems, and designing corrective changes. Rolls-Royce maintains an extensive mathematical model library to support such efforts.

Concept and preliminary design - A DRA is frequently used to verify machinery design and selection prior to placing equipment orders. DRA can determine if candidate machinery components will yield adequate system response without encountering excessive loads.

Detailed design - DRA is used to design the supervisory propulsion control algorithms and verify that the final system design will respond well and not exceed any limits of safe machinery operation. Both normal operation and failure modes can be analyzed via DRA.

This new approach is the result of rigorous analysis considering performance, safety, reliability, maintainability, capital and operational costs.
