Ollie:
Just get it and sail! The new Nacra Infusion is an answer to the Capricorn. You will not be able to get it in the US probably till about June though. That is if you did not deposit for an Alter Cup boat.
I think that the Infusion is fun to sail. A little weird to weather compared to the Tiger. The Tiger will track a bit better. Heavy rudders I had as well, until I did a lot of tweaking on the Tiger. The Infusion is a bit loosy goosy on the helm. This makes is so easy to turn that one may over steer it. Must keep your disipline.
Downwind it is really fun. The Tiger tracks a bit too much I think downwind making you really pay attention to keeping the boat going in the same direction and changing it very slowly. There is truely a planing feel to the Infusion downwind. It feels as though it is on a plane or wants to get there. It will also hold a lot more crew weight as the hulls are very bouyant.
I say go for the Capricorn and we will see how it works in Illinois.
Hope you sell your boat to someone really interested in performing in the Formula 18 Racing. Good Luck, and say hi to Kelly.
Later,
Dan
