Do you feel you have gotten your anwers?

Pretty much the way I see it.

A-cat ;

-1- good international fleet.
-2- Striking upwind performance
-3- extremely lightweight
-4- only for solo sailing


F16

-1- The biggest rush you can ever get while solo sailing. Downwind under spi in the trapeze is it !
-2- More robust than an A-cat. It will take 2 adult in 20 knots of breeze without a care. So near impossibel to break singlehanded
-3- For solo sailing and double handed sailing. Taking somebody along
-4- More of a Open class regatta boat + distance races. A-cats stick more to themselfs as they get hammered by spins
-5- Cheaper than an A-cat when featuring more stuff
