Curve Network Command not working

First thing, I am using Curve Network to generate surface for my boat hull. But its not generating in whole wireframe. I have given a picture of it.

Secondly, which surface command will be good for Trimaran 3D Hull Design.

Thank you

can you post your curves?

fwiw- network surface is likely not the best path to a good model- and your curves are violently over complex given your likely intent.

I highly recommend this playlist in it’s entirety
