Network from Curves query

hms rattlesnake.3dm (388.5 KB) Hi there,

I am still quite new to Rhino and I am currently trying to create a surface using the network of curves tool. However I am struggling to get the correct surface using the lines I have. How could I go about creating this ship using 1 surface, whilst get the bow and stern of the ship all in 1 piece.


edit: link added. Thanks pascal
