The US NACRA 6.0NA, which is what we sail, has about 10% larger a Mainsail then the European 6.0s. The US masts also sport a double diamond wire arangment not found in Europe. A stock Nacra 6.0 NA rates 97 Texel without a spinnaker. This from measuments by Peter Vink at the 2001 Curacao Regatta. With small jibs and no spinnakers, we rated 99. US inter 20's rated 94.
