So, are you saying that if the sail area is 18 square meters, ANY boat can be an 18-square, regardless of the length and width of the boat?
Length is controlled, not to exceed 18 ft. Width is not controlled. Back in the 80's, they had a Cat. II that was also limited by mast circumference (20" max.) and weight (not less than 330 lbs.). Very open rules for this class of cat!
