Good LORD! Will you guys knock it off with the old and tired "my boat is better than yours" crap? I've beaten plenty of boats with my 04 Nacra including Tigers and Infusions, and I've also been beaten by plenty of them as well as identical boats of the same heritage.
Hey Jake, just to throw a little Hijack in, how do you think a Nacra F18 would go if you put an Infusion rig on it????
I perosaly don't think the Nacra F18 platform is that slow. NOTE - This is not based on experience but observations from regatta results around the world. I have heard from many that the NF18 main is very dated and later model mains are a bit quicker. Also the wing mast is believed to be more efficient than the pear shape mast. Once again this is based on rumors but does not sound too far off the mark to me.
Just recently I sailed a Tiger with a Capricorn mast and a Pablo main and it felt very powerfull. This had a lot to do with a very good rig / main combination well tuned.
The best part about the F18 class is you can mix and match parts if you desire, from different manufactures and still be class (F18) legal.
