So that would be about 7Kgs per 100Kgs or 7%.

On that basis my boat could actually be close to min weight <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" /> or it could also be 16Kgs over <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />!!

Interestingly, waaay back in the early eighties at Kiele Woche, the Tornados were weighed in using 4 identical 'bathroom' style scales - obviously they were properly calibrated pro types. It was the first event where we weren't weighed from a gantry and it was the first time my boat came out under and I had to find another half Kg!!!

Being out of things for such a long time now, what's the 'standard' practice? Is it still a case of hanging the boat?
