How this distance is worked out

NaviBoss routes on a network of professional shipping lanes that keeps right through traffic separation schemes. The distance runs from the pilot boarding place at Shanghai (Baoshan Anchorage pilot exchange (inbound)) to the one at Houston (Houston), the same figure the planner gives for the two ports. Distances are great-circle nautical miles along that network. Seasonal Arctic routes are left out.

The same voyage the other way, Houston to Shanghai, is the same distance.
