The Catalina Adventure was built by the Geoshipyard in New Iberia, Louisiana, USA as a high speed ferry for 149 passengers. The aluminum craft was designed in collaboration of FASTcc and Viking Fast Craft Solutions in Staunton, Illinois, USA on the typical Hysucat hull with a tandem foil system of which the rearfoil attack angle is hydraulically operated by the helmsman at speed.
The 24m ferry is propelled by twin Caterpillar C32 Diesel Engines with 2 * 1045 KW at 2100 rpm�s and displaces fully laden about 64t. Inclined shaft 5 bladed propellers in propeller-half tunnels are driven through ZF2550 gearboxes.
The top speed during trials was 34 knots and fully laden 31,5 knots, but operational speed is maximal 30 knots at 80% MCR. The hydrofoil system design and the hydrodynamic and propulsion data were conducted by aid of the Mathematical Hysucat program which was developed by FASTcc and which gave a good agreement with the achieved trial performance data which show that the fuel consumption of the foil assisted catamaran is considerably better than for usual craft.
