The Stealth Design Hydrofoil System started some 20 years ago when Professor Gunter Hoppe from Stellenbosch University in Cape Town South Africa was asked to try to improve the performance of a military patrol boat with a catamaran hull.
Professor Hoppe designed a special hydrofoil that fitted between the catamaran hulls and found that the performance improvements were dramatic.
A research project was initiated at the University and the unique Hydrofoil Supported Catamaran system was born.
The Hysucat system as it is known as was adopted by Malan Conradie, designer of the Stealth Design Hysucats, and under the mentorship of Professor Hoppe, he began building semi-rigid inflatables for the consumer market.
Over time, the hull design was altered and improved until Malan felt that he had got the best shape and performance available and this hull-design is the one that has now been implemented throughout the range of Stealth Design vessels.
Effectively what the hull achieves is a smoother, faster, more economical boat. The technical reasons for this are that the centrally-mounted hydrofoil lifts the hull out the water even at low planing speeds, thereby reducing the wetted-surface area of the hull. This creates significantly less friction and performance is, logically, improved. Power required to plane the craft can then be reduced and the savings in engine revolutions translate directly into fuel savings. Engine life is also improved by not having to constantly work at high revolutions.
The end result is a much softer, smoother ride than conventional hulls, and the ability to achieve high speeds with rapid acceleration is truly amazing. To cap it all, the performance improvements can be seen even with relatively low-power engines.
Now in conjunction with Watermarque Marine LTD we are forging foward to the next level with Hysucat Ribs and hard boat Designs for Water Transport (Water Taxis),fast fisher boats and personal water transportation
