Need help with stern of ship

If anyone creates model ships in this community, then this might be a good topic for you.
I am trying to make a cruiser type stern similar to that of the RMS Queen Mary, however, I do not know how I would be able to. Guided loft, what I figured would work for this project, doesn’t. If someone could find a solution as to how I could recreate the stern design, that would be helpful.

I would use loft. Not guided loft.

I sketch the outline and each cross section profile and loft tool to create the whole body. And the use union tool to join in one when not able to loft in one time.
