A page of two diagrammatic representations of the Irrawaddy and Ganges, presumably built using the same dimensions. The upper is a front elevation depiction of the hull, bisected to distinguish the contours of the bow (left) and stern (right) and their respective measurements. The lower image depicts a partially-sectioned plan view of the starboard side of the hull, featuring only the stern and bow areas. The scale ratio is an eighth of an inch to a foot.
