HYSUCAT

HYSUCAT stands for Hydrofoil Supported Catamaran and describes a novel hullform developed by Prof. K.G. Hoppe at Stellenbosch University.  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.
