Yeah, a wider Acat with more sail area and equal amounts of spin and only a slight bit heavier.
Thats the ticket.
I made the HT 8'6" wide and she's really nice now singlehanded. The mast is too heavy to right with one person, so its not a perfect single hander, and over 15knots I'd be in trouble, so 20sq main is too much.
How about 15m2 main, 20m2 kite, 18ft long, 30ft mast, 8'6" wide and 90kg all up?
