It was on this thread, and then it was said that the 16ft square refers to sail area, just as for the 18 square. Nothing was said about meters.

Sorry if I am being a dumb blonde again. However, this is the first time I have ever heard that 18-square refers to the sail area. I thought it referred to its length and the fact that it is so WIDE.

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? <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" />
