What are hydrofoil supported catamarans?

The simplest way to describe the hydrofoil system is to imagine a wing much like an aircraft's wing fitted on the bottom of the boat that creates lift, caused by the forces of the moving water as would the air on an aircraft's wing. This lift then elevates the hull of the boat out of the water so that the hull only touches on the planning surfaces and reduces a high percentage of the drag that would normally result due to friction on the wetted surface of the hull. The less drag the more efficient the hull performs and the more economical the boat becomes. The other aspect that is often forgotten is that as with an aircrafts wing the resultant lift created by surface movement is also able to support large weights, which means that when the boat is heavily loaded the load is not noticeable as with other conventional hulls. The Hydrofoil Supported Catamaran (HYSUCAT) is a hybrid of a catamaran hull equipped with a hydrofoil system between the demi-hulls which carries a part of the crafts weight at speed. The effcient load carrying capability of the hydrofoil system in combination with the inherent stability and pleasant seakeeping properties of the planning catamaran results in a most economical high speed surface craft with excellent seakeeping behaviour. The specific hull design is an asymmetrical catamaran hull with a centre-pod rounded tunnel. Specially designed and patented sprayrails which were incorporated into 24 degree deadrise hulls. System benefits: Fuel efficient, Increased speed, Increased stability & Comfort Less resistance, more maneuverability.
