The port is located in the Satellite area. In the storyline of Yu-Gi-Oh! 5D's World Championship 2011: Over the Nexus this is where Jack Atlas' Duel Runner was taken after being stolen.
A port is also accessible in Yu-Gi-Oh! 5D's World Championship 2009: Stardust Accelerator but is not a location on the map; it is instead accessed from Satellite: Slum. A Travel Permit allows the player to travel on a ferry between Satellite and New Domino City.
