Wave cancellation small waterplane multihull ships
- CRDKNSWC, Bethesda, MD (United States). David Taylor Model Basin
A new patented wave cancellation multihull ship concept (Hsu, 1993) is presented. Such ships consist of various arrangements of tapered hull elements. The tapered hull design provides a small waterplane area for enhanced seakeeping while producing smaller surface disturbances. In addition, proper arrangement of hull elements provides favorable wave interference effects. The saving in effective horsepower with a realistic wave cancellation tri-hull arrangement, was found to be about 30 percent compared to small waterplane area twin-hull ships. Power reductions of this magnitude translate to considerably fuel consumptions and improved range. Applications to several ship types, such as for fast ferries, cruise and container ships, appear promising, wherever good seakeeping, large deck space and high speed in the design.
