Network curves limitations

The thing is that if one breaks the curves, then the continuity of the hull deteriorates greatly. See this zebra analysis of your model:

A ship hull is a sort of semi-organic shape. It should flow in a nice fair uninterrupted curvature. Accuracy of individual stations is less important than maintaining fairness. It is a perennial problem of mine with NURBS modeling (not that it would be any better with Sub-D obviously).
