# Vessel displacement and draft
# Scope: Fresh or salt water hydrostatic displacement at supplied density.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

mass = 100 kg
density = 1025 kg/m^3

displacement := mass/density [L]

check displacement volume budget: displacement <= 120 L

scenario alternative: mass = 80 kg
