Suggestions for a newbie how to recreate weird shape?

Can someone give me some general directions how to recreate the shape of the hull of this thing in FreeCAD? https://collections.museumsvictoria.com.au/items/393586 I tried making several horizontal sketches and additive lofts between them, but that way I cannot recreate the curvature on the side (like the black band that goes up on the side towards the fore). I also tried Curved Shapes workbench but that's apparently the same thing but automated. It'd be ideal if there was a way to recreate it with "faces" connecting where they are in the original (the seams).
