Modern power catamarans of planing type are investigated. Data are presented about small high-speed catamarans (40 feet, less than LOA, less than 100 feet) which have seen oceanographic, survey, excursion and fishing service. A table of characteristics of recently constructed catamarans is included. Some results and observations based on extensive parametric studies of asymmetrical and symmetrical planing catamaran hulls are included. Curves of R/D versus speed for various displacements, hull spacings and hull forms are presented. An attempt is made to relate size, weight, power and performance by comparing known performance to model test data. Considerations involved in the design of catamarans such as structural strength, powering, stability, handling peculiarities and weight criticality are discussed. Methods of predicting weight, cost and considerations for trade-off analyses are presented.
