Ship hull kinks

 From:  JPBWEB
Hi guys,

I am working on a ship hull, a T3 Fleet Oiler of the US Navy, using my usual method of basically Network command to generate in one go the entire half ship. This works quite well (see below) but there is an unwanted kink showing in the bow area. There are several ways to handle this, such as using a blend between the two halves, like in the stern, where a kink is wanted by the way. But surely, Network should work well with such simple flowing curves. The curves over there are smooth, fair and all that and there should be continuity from one side of the hull to the other. Such continuity happens correctly with the flat bottom. I really wonder why. Any thoughts ?

I also include the 3dm model for illustration purpose.
