kato said...I,m just over 10,000kms,does that count

You'd need to average 1km/hr and I suspect your a bit faster than that Kato!
But in my last 5 years in the GTC I'm over 16,000kms, if you extrapolate that to the 20 years previous to that, I'm around 80,000 kms so I have to average 8km/hr. (not really valid, I've sailed more in the GTC)
May be possible if you take into account all the low wind wave sailing I've done over the years.
