      Asymmetric hull form is not unknown in catamarans, So perhaps the bodyplan is OK.

      Nay, YOU must redraw it.
      And just think it like a surf on pornhub, a nautical one indeed: if you do not enjoy it it does’nt worth…
      Take your file, delete all but the hull, dittch all those crease lines: THE GRID IS NOT A CAGE, points and edges define by parameters the meshe’s curvature, mark.
      Just for ex. have a look at my post on ‘double skeg’ it’s a (poor) sketch where few points define a surface: check always with “mesh” button.
      The awkward part is guess the submerged hull lines, but do not panic: must be an usual displacing hull or variations on it, you can do a good job.
      Cheers.

      Hy, just a Post Script.
      Apologize, my answer was on your first post, but it’s ok ( I think ) also for the second.
      Drawing multihulls needs some skills AND some tricks to achieve them.
      Try to design the hull like a monohull, then..
      Practice makes the wise man.

      Hi,

      A trick you might use is to create a separate horizontal intersect layer with lines where your stations are. This should pass through the side of the hull you consider good. It may help to temporarily move the hull to be centered on the Y-axis. With resolution at its highest setting then use the intersect command to put new lines into the intersect layer. These points represent where your hull on the good side was passing through the intersect layer.

      You can use these values as basis for the opposing side.

      But since that side has a hard corner it may help to add a new hull line just below the hard one by using the intersect layer as above, just lowered a bit. This would help you reproduce the shape of the hull on the good side a bit more precisely.

      EDIT: just realized my misspeak. Rather than “stations” it should be “control points”.
