Stowage Factor & Cargo Intake
How much cargo actually fits — by hold volume and by deadweight — plus a TPC draft-to-displacement check.

Intake = hold m³ × (1 − broken stowage) ÷ stowage factor; deadweight available = DWT − bunkers − fresh water − stores − constant. Grain vs bale capacity, deck loads and trim/stability limits still apply.
Draft / TPC check
Linear TPC approximation — accurate within ~0.5 m of the reference draft; beyond that use the hydrostatic tables or deadweight scale.
Method
The intake calculation planners run first.
Volume limit
Hold m³ × (1 − broken stowage) ÷ stowage factor — cubic-limited cargoes fill the hold before deadweight.
Weight limit
DWT − bunkers − fresh water − stores − constant — heavy cargoes hit deadweight first.
TPC check
Draft→displacement by tonnes-per-centimetre — linear near the reference draft; hydrostatics beyond that.
