I am having some trouble with a filled surface. The images below demonstrate the outputs according to which constraint curves I choose.

I'm looking for ideas how to constrain the surface so it comes out smooth. Executed identically in Fusion 360, it comes out fine.

1) Selecting all rib sections (ignoring waterlines):

2) Selecting all waterlines (ignoring rib sections):

3) Selecting only the patch boundary, with no constraint curves:

4) Selecting all rib sections and all waterlines:
