WAVEPIERCING YACHT DESIGNS

   The principle of Wave Piercing Catamarans

   The Wave Piercing Catamaran is a good example of innovation through the combination of two technologies. The traditional catamaran, developed over
    the centuries by South Pacific cultures, is a fast, stable, two-hulled boat, but on choppy seas it gives a rough ride. In 1984 New Zealand-born Phil Hercus
   successfully combined the strength and speed of the    catamaran with a wave-piercing hull design called SWATH (Small Waterplane Area Twin Hull).
   SWATHs are used to stabilize    giant oil platforms.

   Hercus's new-style cats ride steadily above the water while their hulls plough through the waves. They've been built in Hobart since 1984. Constant
   development of the Wave Piercer design has led to larger vessels with increased speed, capacity and reliability.

   Ninety-six meter long catamaran ferries now ply the oceans carrying up to 950 people and 300 cars while averaging 41.2 knots. Larger vessels of 120
   and 150 meters length are in development. Cargo configuration is flexible and uses mezzanine ramps to adjust the arrangement of cars and trucks.

   In 1989 an Australian-made Wave Piercing Catamaran set the speed record across the Atlantic Ocean on its delivery voyage. In 1998 another Australian
   made Wave Piercing Catamaran took the record.

   Phil Hercus and Robert Clifford received the AO in 1995 for service to the shipbuilding industry. The manufacturer, Incat Tasmania, has built over 25 large
   fast ferries.

   The company turned over $200 million in 1999-2000, employed over 1000 people and had sold its ships in Northern Europe, the Mediterranean, Britain,
   Korea, Japan, Argentina, North America, Australia and New Zealand. The Royal Australian Navy has operated an Incat vessel between Darwin and Dili
   in East Timor to transport Australian and United Nations Forces.

   Incat has never patented its three hull design, relying instead on keeping ahead with the technology. In 2000 their innovations included a retractable
   T- foil small winged keel) to increase passenger comfort in high seas. The company also utilizes an on-board computer system so that if problems occur,
    images can be emailed from anywhere in the world to the projects section for troubleshooting and action. This post sale service includes a 24 hour
   response team available worldwide.

   Thanks to the big ferry companies funding the research,fine-tuning and testing of the Wave Piercing hulls, this technology is now available at affordable cost
   for smaller passenger,private and charter yachts, a few samples of which are shown in these general arrangement plans. Most of the yachts are custom
   designed/built to owners special requirements.
