Introduction to Six Kinds of Cats and Two Kinds of Tris by Calvin H. Markwood The analytical method used in Analysis and Comparisons of Cruising Multihulls[1] to compare various catamarans and trimarans can also be used to compare design approaches of various designers. Its a sort of reverse engineering thinglook at the results and infer the approach. Performance and stability are the primary characteristics that can be inferred and indications of how the designer achieves them are often apparent. What cannot be inferred are provisions for living while sailing, esthetics, windage and others. Drawings and pictures in the magazines, books and plans provide much of that. The catamaran designers are Brett Crowther, Kurt Hughes, Derek Kelsall, the team of Morrelli and Melvin, John Shuttleworth, and Chris White. The trimaran designers are Ian Farrier and

Although this article is intended to stand alone, a fuller discussion of the various design, performance and stability parameters is contained in the other article.
