Although it has diversified into other vessel types in recent years, Western Australian based shipbuilding group Austal still counts fast ferries as a core market. The last year has been no exception, with the biggest news being the June announcement of an order for what will be the world's largest high-speed multihull vessel. Even more significant than the vessel's 126.7 m length overall is the fact that the cargo-vehicle-passenger ferry will be based on slender stabilized monohull hullform (more commonly referred to as a trimaran). While the experienced high-speed builder from down under touts the commercial value of the project, ramifications for its military aspirations, particularly with the U.S. armed forces, are clear.
