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 Rotterdam (Maas Center Buoy (Maascenter)) to the one at Busan (Busan Port Pilot Station No. 1), 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, Busan to Rotterdam, is the same distance.
