It seems that Greg Goodall, himself, is claiming that the VIPER is a F16 and a F104... I don't quite get it as for me the mininum overall weight for a F104 is 135kg...
I will also add that I don't understand how the same boat could claim a F16 rating (of 1.008) and a 1.04 rating. It's either a very slow F16 or a very fast F104. <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" />

After several weeks now, this is still not clarified and this has some influence in the french catamaran sailor community...
