Luiz,

It might interest you that a 40 kg kid will be able to match a Laser-1 sailed by a 80 kg adult and not feel more powered up then that 80 kg guy.

40 kg kids are on average 12 years of age. Of course there is nothing wrong with placing two 8 year olds on the boat who are combined 40 kg and pump out the same performance.
