To revive the 18 would be a great idea, especially for European catsailors who would discover these big A-Cat.
The point is to make these boats competitive for a Texel round or any Interserie regattas.
The boat should allow a single-hand crew to compete with a Marström M20 GTI (27 sqm sail area = Close to 300 sq feet)

So the points will be: the weight and the kite area.
