The naval architecture and engineering advances made strengthened the core knowledge base of DLBA, Babcock and S SPA. Development and interface of gas turbines (by two separate manufacturers) into the Renk gear box brought new technologies of smaller power density turbines to P&W and Rolls-Royce. The Classification Society, DnV benefited by lessons learned working with a motor yacht with such a high power density propulsion plant and Noise and Vibration advances were made by J&A, ISVR and Babcock.

In summary extensive hydrodynamic and aerodynamic programs were conducted to advance and develop new technology to achieve the performance capabilities of motor yacht Alamshar. This yacht exhibits exceptionally good ride quality in seas. Model testing in irregular waves validated new refinements to further improve double-chine hull, sea keeping which has been known for some time to be markedly superior to planing hulls. Further, the inclusion of systems for dynamic control of pitch and roll motions fine tunes ride quality.

M/Y Alamshar demonstrates innovative technology throughout the entire design of the yacht. It represents significant advances in propulsion efficiency, high-speed sea keeping, dynamic stability, acoustics, marine aerodynamics and the interface of operating crew with systems for safe high- speed navigation. The extensive model testing, investigation into propulsion system parameters and concomitant sea keeping research have led to a vessel which is capable of achieving 700 nautical miles at speed in excess of 45 knots at full load, 950 nautical miles at a transit speed of 35 knots, and 1040 nautical miles at 15 knots.

Many of the features of this high-speed, seaworthy yacht are expected to find their way into other marine service, possibly military and paramilitary operations.
