I have to say I am VERY disappointed in all of you. 12 hours in and noone has said anything particularly contentious - I think I'm going to ask for my money back on this one!

I could always just throw a little fuel on the fire with this statement from Nacra:

"Nacra F18 Infusion.
In Formula 18 racing, all producers have to try to top of the racing results and therefore on top of the market. All sailors know that Formula 18's are innovative racing machines and therefore will continue to change to meet the demands of the market.The Nacra Infusion is made with the latest production technology and hull design by a company famed for quality production. The Nacra Infusion is the most innovative sports catamaran on the World market.
The Nacra Infusion is the only production catamaran that is made with infusion technology."

OK - more popcorn, please!
