STEALTH hysucat ® The HYdrofoil SUpported CATamaran (HYSUCAT) is an integrated design comprising a catamaran hull equipped with a hydrofoil system between the demi-hulls which carries a part of the craft’s weight at speed. This development reflects 30 years of Professor Karl-Gunter Hoppe’s research before and while employed by the University of Stellenbosch, as Senior Lecturer in Fluid Mechanics and Marine Engineering. The efficient load carrying capability of the hydrofoil system combined with the inherent stability and pleasant seakeeping properties of the planing catamaran result in a most economical high speed surface craft with excellent seakeeping behaviors. The specific hull design is an asymmetrical catamaran hull with a centre-pod rounded tunnel, with the foils fitted forward and aft. The vessel appears only slightly beamier than a comparable mono hull without the cumbersome aesthetics of a catamaran, the best of both worlds.
