There must be some correction on one answer. The average weight of the Blades measured during the Global Challenge is not 118 kg but 114.3 kg.
The lightest boat was carrying a carbon mast and weight 105.8 kg and the lightest one with alu mast was 109.8 kg.
All latest models Blades (2007) are around ( +/- 1 kg ) around 110 kg.
