Hi, the network command need a very well coincident curves to avoid any deformation, the best workflow is making hull with the loft command a or with many patch and better curves, here you can see this made now in less than 15 min but I suggest to search for hull design for Rhino in YouTube ,there are many tutorials, and is very hard remaking hull from all the lines in the lines plan maybe, you can try selecting few of them for a better smooth surface otherwise it will be difficult to obtain a smooth surface, you must consider that the precision of the surfaces also depends on your precision in making the sections.

this hull is done with network curves and many blended surfaces and lofting on bottom hull
The lines are in the file
