Where do you start and stop?
Ehhh, you start with the obvious stuff like the contours of the spi, mainsail and selftacking jib and you stop when you run out of the obvious stuff or run out of time and resources.
Currently we still have time and resources, so ....
Actually, adjusting the nose to show a more wave-piercer like hull is a good suggestion Taipanfc, we'll add that one to the list. The drawn daggerboard has an aspect ratio of 3 (Taipan/older Blades 1.8 ; new Blades 4) and are a good average if you ask me.
