Question

How long did the Middle Passage last?

Answer 1

Roughly 80 days
The Middle Passage itself lasted roughly 80 days, on ships ranging from small schooners to massive, purpose-built "slave ships." Humans were packed together on or below decks without space to sit up or move around. Without ventilation or sufficient water, about 15% grew sick and died.
