AUSTRALIAN MARITIME REVIEW loadings comfortably above the contracted speed of 29 knots.

These latest deliveries are num- bers five and six in a string of sim- ilar-design monohull vessels built last year, each with basically the same hull design and similar three engine/three waterjet propulsion systems. While six of the vessels delivered last year are monohulls,

Wavemaster demonstrated its flex- ibility with the delivery of three catamarans as well. A pair of 144- ft. (44-m) vessels were delivered to

Iranian operator Valfajre-8 for operation in the Persian Gulf.

Each vessel can carry 236 passen- gers, 10 large vehicles and 16 cargo crates of up to 28.5 knots. The other catamaran was a smaller, 80.5-ft. (24.5-m) vessel built for

Japan's Ezaki Kisen. Delivered in

June, the vessel marked the com- pany's first delivery to Japan.

Speed & Quality By Design

Australia's Advanced Multihull

Designs (AMD) has designed what it dubs the world's fastest car ferry, a vessel built by Spain's Bazan.

The 252.6-ft. (77-m) catamaran —

Luciano Federico L — was deliv- ered to Buquebus in October. It is a gas turbine-powered version of the AMD 1130 design and is to be operated on the 130 mile Rio de la

Plata route from Buenos Aires to

Montevideo. The vessel can carry 450 passengers and 52 cars, and reportedly achieved trial speeds of 58.7 knots propelled by a pair of

ABB GT35 gas turbines, which together develop a shaft power of 32,200 kW. Each gas turbine is coupled to a Kamewa 112SII waterjet through a Renk gearbox.

To ensure stability, handling and comfort, the vessel is outfitted with an active Maritime Dynamics trim tab ride control system which was especially designed for the vessel.

The design objectives clearly state that the end product must have a speed as close to 60 knots as possible, while maintaining tight control on build, outfit and opera- tional costs. A concept design was developed by AMD based on these designs objectives and the owner's requirements. With approval of the concept by Buquebus, AMD proceeded with a full technical design. Bazan was chosen by the owner to build the vessel, and the technical design was input into

Bazan's Foran computer system to produce shipyard drawings. Due to the high operating speed, a new hull form was developed. The design was optimized with a model test program carried out at the

HWA Zhong University in China.

A larger model of the final hull form was then built and tested in the El Pardo Towing Tank in Spain to verify performance.

Never to be under estimated, the power of the sea demands the best from all of us, and for navigators only the best can be good enough.
