"HY-SU-CAT" stands for Hydrofoil Supported Catamaran and describes a novel hullform developed by Prof. K.G. Hoppe at Stellenbosch University in South Africa. We theefore only refer to HYSUCAT as a type of hydrofoil design together with hull form NOT in anyway to be used here as a trade name or reference to any others

​The design consists of a novel catamaran hull with a hydrofoil system located in the tunnel between the hulls of the vessel. 

           The hydrofoils support 40-60% of the craft’s weight at speed and lifts the hull partially out of the water. 


           As the hydrofoils have a much better lift to drag ratio (L/D=20) than a planing hull (L/D=5) the result is a craft with much lower resistance than a conventional planing hull.  This lower resistance can be applied effectively to: 


· Increase the speed of the vessel without having to increase installed power

· Reduce the fuel consumption and increase the range of the boat

· Increase the payload of the vessel
