Hopefully we can assume stock SH4 was correct but it will have suffered from Chinese Whispers as mods evolved and grew.
If folks are wondering what these silhouettes look like, here is an example of the Ansyu Maru. It is shown here on a white background but the actual texture is transparent to allow the page of the RM to show through. Top half is the normal view. Bottom half is the "offset" view.
The outline of the vessel is emphasized with a slight "stroke" to show up the rigging and masts more clearly.
