1) One person can put the mast up on their own and we are still quicker than an F18 to rig or de-rig (not that it should matter). 2) No Irish A class has ever taken off down the dingy park or has even attempted it, we leave our boats unattended every time at the top of the slip as we get changed with no issues.

Even if what you were saying were true, it would be a very small price to pay for sailing an amazing cat.

Also on the "Tradition" point raised on another post. Where would most classes be today without the development of the A. What class was the first to have Square top mains, what class was the first to have a Wing-masts, what class was the first to have Wave piercing/reverse bows, the list goes on.
What you see on an A-cat today, you will probably see it on other classes as time goes on.
I am not saying the A-Cat is better than any other, but it is definitely a necessary class and great fun.
For those of you who have never sailed one, you can not comment. Sail one then come back to me a tell me how terrible they are.
