It´s ver good try. Maybe a few bumps.
I usually avoid that using loose options (I know it´s not the good way)

Well. It has been a hard week, but I send you my last hull, if you want to see.
As I told you, I have draw the curves, after I have rebuild them with the same number of points, and finally I have created the surface using Loft command.

Bye!
