Nacra Inter 18

The Nacra Inter 18 is the first American Formula 18. Equipped with high ratio appendages, she is really performing upwind and maintains good speed downwind. However it is quite difficult to run on wavy seas because of the lack of volume on the fore hull. The Harken fittings and Vinylester foam sandwich construction are of high quality.

See the Nacra Inter 18's specifications on Boat-Specs.com.
