Great work, very interesting posts!
I'm interested in design, especially the America's Cup boats. I did a lot of analysis of the AC75 foiling monohull, and now I'm into the SailGP F50, which is a foiling catamaran derived from the AC50.
As no plans are available, I drafted up my own in Inkscape from heaps of images from videos, plus a few published dimensions. Unfortunately I can't find how to insert an image from my pc in this forum?
Anyway, I wanted to try CAD, so started with Fusion 360 a couple of weeks ago, and have finally managed to Loft one of the hulls. I used a number of the techniques described above, but there were several I haven't learnt about yet - very interesting.
