I also agree with Mary and Rolf, there are allready a bunch of suitable cats for teenagers, but not for youngsters. So why bother with yet another one.
I think the 12ft F12 is a great idea for my 3 chidren age 5-10 (I'll leave the 7 month out of this discssion). They have an Oppie but I feel there are many advantages in a cat not least the greater stability.
I thought this is where the dscussion started and it then drifted toward a higher performance cats that could also be sailed by a lightweight adult. For which I see no need.
