Performance Catamarans' Nacra 450, descended from the Nacra 4.5, offers the entry level sailor a fast and easy-to-sail catamaran. The boat's buoyancy surpasses that of other catamarans in its size range and its kick-up rudders make for simple beaching and shallow water sailing. A wide beam and jib blocks mounted on the front crossbar leave the trampoline uncluttered and more comfortable. The boomless main allows for easy control and the jib is quick to tack and maneuver.The Nacra 450 is offered in a variety of bright and brilliant colors.
