Don't look at the H14.
Picture yourself an F18 or Spitfire / F16.
I'm using the same scaling laws as I did with the F16's
In principle this would lead to a F12 with the same performance as the F18, despite being much smaller. But for true equality it would have to be fitted with jib and spi. Sadly there is a thing that I call the Quad-problem and it limits the amount of sail area you can put on the F12 before it turns into a right submarine. Therefor we are not going to achieve full F18 performance. But I have a feeling that we'll discuss this soon enough.
