What you all forget in this discusion is that there are many sailors who are not interested in racing. And if you are looking for a light weight singlehander and you don't want to buy a used A-cat, this A-cat could be the answer. It is cheap, still runs circle around most of the other boats and, if you need a new sail after some years, you can buy a good used sail from the A-cat top sailors for a very reasonable price. Such a sail is probably still better than most of the new (stock) sails of other single handers...
80 or 90kg is a dream to move around the beach and to rigthen after capsize, if you are alone. However outside of Europe people will not profit from it, due to exchange rates.

Cheers,
