It's going to be difficult to sort fact from fiction in this thread!

I would certain rank these as the fastest - although I would say that the Marstom 20 (there are two that race in the southeastern US) has not proven to be the performer we all expected it to be. 30 knots? While I think 30 knots is possible in a short burst (just before capsize) I don't think it is realistic to be able to sustain anything near 30 knots on any of these boats. I have not seen an Eagle in competition with other boats but I suspect that it might scare off the Olympic Tornado for outright speed. I have taken part in extensive racing between Nacra 20s and the Marstrom 20s and the Marstrom has displayed a moderate advantage over the Nacra (especially considering that it is about 1/2 the weight AND wider).
