Nacra
NACRA ( North American Catamaran Racing Association ) is a class of racing catamarans that developed in the USA and has spread to Europe and Australia. There are different sizes and types within the NACRA class, from sailing school boats to racing boats.
history
The first NACRAs were developed and built by Tom Roland in California , USA. The first models were the Nacra 5.2 and 18sq. They were revolutionary boats with "teardrop-shaped" hulls. Roland's ideas and design have had a huge impact on modern multihulls . Today many large multi-hull boats are built with this hull shape.
NACRA catamarans are produced by Nacra Australia in Brisbane , Australia , and by Performance Catamarans Inc. in California, USA.
The Nacra 17 catamaran will be used as a boat for the Mixed Multihull category at the 2016 Olympic Games in Rio .
