NACRA (North American Catamaran Racing Association) is a class of racing catamarans originating in the USA with adoption in Europe, Australia, and many island nations.
Within the NACRA class are a variety of catamaran sizes and styles ranging from resort hire boats to performance racing.
History
The first NACRA's were built and designed by Tom Roland in California. It was a revolutionary boat with vertical seams and a teardrop hull shape. He established the Nacra name with the creation of the Nacra 5.2 and 18sq.
His idea and design have been a major influence in today’s multihull world, with many large multihulls still using this hull
shape[1]. NACRA catamarans are currently built by Nacra Australia in Brisbane, Qld, where Nacra has been produced since 1985, and by Performance Catamarans Inc. in California, USA.
