HYCAT: AN ALTERNATIVE HYDROFOIL TRANSPORTATION SYSTEM

A hybrid marine vehicle concept termed HYCAT, for Hydrofoil CATamaran, combines a planing catamaran hull with fully submerged hydrofoils. HYCAT has resistance and seastate characteristics midway between those of surface piercing and fully submerged hydrofoils. The development of the HYCAT prototype is being supported by a Concept Exploration Model <CEM> computer program comprising nine technical discipline modules. The HYCAT CEM has been used to develop the configuration for a prototype passenger ferry with a gross weight of 99.5 long tons. A comparison of the HYCAT performance with current advanced marine transportation systems indicates that it will have a dollars/seat-kn figure between 509 and 611, which is at the lower end of the 572 to 1326 dollars/seat-kn range for these vehicles. A series of tow tank tests of a 1/40.3 scale model has been conducted in both calm water and regular waves, while a 1/22.5 dynamically scaled, free-running radio-controlled model will be used to assess the manoeuvring characteristics of HYCAT.
