A warship was an exceptionally inefficient container of space.
Seventy percent of a dreadnought’s shifted weight was dedicated to heavy iron armor plates, gunpowder magazines, solid iron cannonballs, and massive coal bunkers needed to feed inefficient fire-tube boilers.
The actual payload—the cargo capacity that produced economic value by moving goods across geography—was less than ten percent of the ship’s gross weight.
In naval stonework, every ton of dead armor plate carried across the sky burned up nonstop floating lift and fuel energy while producing zero economic return.
When an engineer stripped the armor belt, removed the heavy cast-iron cannons, and replaced coal fireboxes with underground steam accumulators, the ship’s metacentric height improved dramatically.
The balance point shifted downward into the lower keel. That let the hull carry four times its original commercial payload in complete water-flow balance.
To a royal admiral, an ironclad was an instrument of territorial terror.
To a civil logistics engineer, an ironclad was merely an overpowered steel hull waiting to be stripped of dead weight and converted into high-volume intermodal freight transport.
