Upper decks normally carried lighter guns because every heavy weapon placed high in the hull raised the center of gravity. Mounting full 32-pounder batteries on two decks would require unusual beam and draft to recover stability. The panel invokes Vasa as the warning: uniform heavy gun decks looked powerful but produced a dangerously top-heavy ship. The example links gun calibre directly to hull form, stability, and seaworthiness rather than treating artillery layout as an independent choice.

Why Vasa warns against uniform heavy gun decks
Vasa illustrates why upper gun decks normally carried lighter weapons than lower decks.
