Portland Harbor is based on Brooklyn Navy Yard. Portland Harbor's design is what one would expect from an average seaport. The district only houses a collection of warehouses, loading docks, shipping cranes (large and small), shipping containers and large freighters docked along the harbor's docks. The harbor is revealed in GTA Liberty City Stories to be undergoing upgrades still circa 1998, as a row of warehouses were under construction in the district.
Portland Harbor's apparent links with a local workers union led by Jane Hopper has also resulted in the harboring being shut down during GTA Liberty City Stories Portland Island mission strings, circa 1998, when the main entrance into the harbor is blocked off by harbor workers, protesting in sympathy of ferry workers, who are staging a similar demonstration at Harwood. If the player ventures into the harbor while the workers are still picketing at the gate, the workers will turn hostile and pursue the player, similar to protesters at the Harwood ferry terminal. The protesters at the harbor will disperse once Staunton Island is unlocked with the completion of Driving Mr Leone.
Points of interest
In Grand Theft Auto III, a Colombian Cartel ship filled with SPANK (dubbed Les Cargo) is docked here, but is destroyed in Salvatore Leone's mission "Bomb Da Base Act II". In addition, a garage at a warehouse, first featured during "Van Heist" and unlocked thereafter, will accept Securicars stolen by the player for money. Two Import/Export are also located within the district in GTA III, one, which predominantly accepts commercial and industrial vehicles, is based in a warehouse, while the other, which takes the form of a ship with a magnetic crane, accepts emergency vehicles.
Grand Theft Auto III
- Kuruma (at the car park)
- 2 Mules (one at the car park, other at the end of a roofed area behind the car park).
- Linerunner (far south of the dock).
- Perennial (at the car park).
- 2 Yankees (one at the emergence vehicles' crane, other near some crates at southeast).
Grand Theft Auto III
- Armor (far northeast, near the emergence vehicles' crane).
- Adrenaline (between some trailers south of the car park).
- Police Bribe (under metal structure at south).
- The Les Cargo ship docked in the harbor may have been the inspiration for the Platypus ship seen in the HD Universe. The surroundings too look very similar to that of the GTA IV docks.
