This striking new high speed commuter/tourist catamaran named “Legacy” was designed for it's proud owners Stradbroke Flyer in Brisbane, Australia. To quote John Groom (Owner) soon after loaded sea trials: "Speeds and fuel consumption are brilliant, 23 kn @ 1800rpm and 75 Liters per hour each engine. Red line at 28.5 kn @ 2350rpm.. Doesn't bog down getting out of the hole, just punches well above her weight. Great for our service, the new styling really has stirred up some interest." The ferry currently operates from Cleveland to Stradbroke Island in Australia.

This is the third Sea Speed Design 21 Metre hull to be built using this proven 'Sea Cat 21' hull design and KIT. This enables the builder a quick start using the existing hull 'CNC Kit File'.

The vessel structure is designed to Lloyds SSC Passenger Catamaran G2 rules and built to comply with NSCV Class 1D. The hull form has been optimized for excellent fuel efficiency and low wash characteristics at operational speeds. Modern, intelligent systems will support robust engineering to provide high redundancy, low maintenance and reliable long term operation. It is intended that the fire, flood and safety systems on-board will represent the latest technology combined with best industry practices. The cabin arrangement provides comfortable seating and large panoramic windows. The open plan deck arrangement will provide access to all areas for light and ventilation. Large, tinted windows provide generous views and ample light whilst reducing heat transfer into the passenger space. Seated passengers will be on the main and upper decks. Passenger access will be via port and starboard boarding doors located fwd and aft. A minimum of 150 seated positions will be provided comprising approximately 110 internal and 40 external seats. ”

Above is the 3D preliminary design image prepared prior to construction.

The ferry layout design allows for ease in operation. Passengers can safely and quickly load and discharge at fore and aft' locations. The captain is perfectly positioned to do the docking and oversee the loading and discharge.
