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 Algeciras (Algeciras zona de embarque 2 – semicírculo (origen)) to the one at Singapore (Gusong Boarding Ground (PGBG)), 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, Singapore to Algeciras, is the same distance.
