In addition can a 75 kg person still right the discussed boat unless it is really windy ?
Yes, I can get my boat back up in around F4+ (which is the the only times I've tipped it in). I am 76kg last time I checked.
Can you get a F16 back up in all wind conditions with a 75kg person ?
I don't know about that. The EU I17 has more singlehanders sailing in front of it then behind it; don't know wether that still is sufficient to earn the qualifier "One of the quickest". I'm sure the newer versions like the 17R and sorts are noticeably faster and I always mentioned that.
Are you sure about that?

So F16 is 4th, Inter 17 Eu is 19th from a list of 49 so I think you will find that there are more boats
behind the Inter 17 Eu spec.
And that is simply numeric.
