I have been participating to the F12 class in the way I have been building two protos on the designs of Scarecrow and Ncik. What has become quite obvious to me is that there is a need for a modern entry cat even for the adults. Many adults would like to sail the F12, but it’s a little bit to small if you are over 70 kg. The more or less max displacement of that boat is 120kg (the ready to sail platform weight just under 50 kg). The two extra feet would give the displacement needed and it would be possible for a reasonable price to homebuild a modern cat ready to sail for say around 3000USD.
