Network curves limitations

Actually, I spoke to fast. I used a simple Blend on the edges of the v-shaped hull, which gives a perfect continuity. Varying teh bulge value (within reason), one can get various shapes of pointyness (if that is the right word).

Here is a Flamingo rendering showing a very smooth stem-piece. The zebra analysis shows perfect continuity.

This means problem solved, I guess. At least for such a simple smooth hull form.
