The offsets obtained from the calculations are used to create the envelope hull in Rhino shown in Figure 40.

4.2 Preliminary Arrangement (Flounder Diagram and Cartoon)
As a preliminary step in finalizing hull form geometry and inboard and outboard general arrangements, an
arrangement cartoon was developed for areas supporting mission operations, propulsion, and other critical
constrained functions. Figure 41 shows the SSG(X) Flounder diagram, the first step to arrange the submarine. This
is a plot of cross-sectional area against length, within the envelope hull sectional area curve; areas in the Flounder
diagram represent volumes in the submarine. Required areas from Concept Exploration are placed inside the outer
hull boundaries. This method provides a rough longitudinal arrangement to check and maintain the necessary
volume balance.

Figure 42 shows a preliminary arrangement cartoon. This cartoon was developed from the Flounder diagram
and provides a profile and midship cross-sectional view of the SSG(X). The general arrangements inboard of the
