Here there is also a better resolution movie of the 3D model.
Most difficult was making a3D model of the faired hull. One would think this to be fairly simple, but it proved to be very time consuming as I did it "by hand" There are softwareprograms specifically made for fairing hulls, but I suspect that even then a highly curved hull like the International Dragon class will take some time.
When "free" designing your own hull using a nurbs program like Rhino 3D can be very efficient and quick.
