How it is calculated
- Distance = shortest path along the global shipping-lane network, plus the legs from each port to the nearest lane
- Days at sea = distance ÷ (speed × 24)
- Total = days at sea + port time
Arctic passages are closed by default; Suez, Panama and the other canals are open. Sources: searoute / ORNL global shipping lanes and the World Port Index (both open data).
