Also interesting to read Martin Fischer`s opinion on the weight of the F18s (He designed the Capricorn and the Wildcat), in context of his choice for the next Olympic catamaran : "I think 18 ft with a beam of 2.5 m would be a good choice. Transport is much easier than with a wider boat and such a boat would be significantly cheaper than a 20-ft boat. I would also like to see the weight come down a bit, but not to extreme levels. I reckon a weight of around 140 kg would be a good compromise between performance and cost." http://catsailingnews.blogspot.com/2010/05/cs-interview-martin-fischer.html
Seems he disagrees with Macca on the weight issue, if he believes 140kg would be a good weight for an 18ft, not a 16ft boat.. but then he is only a designer with more degrees than a bar full of catsailors..
