Problem with lofting weird curves

Hi.

I am trying to replicate the method described in [http://www.youtube.com/watch?v=3XkdIsleAqY][1] for modelling the hull of a ship. No problem with the lofting of one side of the hull but, when I try to mirror it and join both sides I cannot do it.

If I try to loft the whole model (mirrored and joined) it does not work either. I think the problem lies in the curves that try to replicate the bulbous bow of the ship.

Any suggestion will be greatly appreciated.sample.3dm (404.8 KB)

Hi Miguel- two of the curves at the bow do not end on the centerline- I would fix that first.

Oh, dear! Thanks from a newbie.
