Is that why an Inter 17 beat an F18 at the North Queensland Nacra Championships? I think you under estimate the Inter. I have seen this thing with its nose well and truely buried and still driving with more available, amazing boat. I don't dislike the 4.9 taipan, and in no way doubt that they are fast, but i would put the Inter up against any 16 footer, VYC or not.
Up here, North QLD is Nacra country.
