Stern's Shipyard (Japanese: クスノキ造船所Kusunoki Shipyard) is a building owned by Captain Stern, featured in Pokémon Ruby, Sapphire, and Emerald. Stern's Shipyard is a large brown building located next to the ocean. In front of the building are two houses, and around the building are three small wooden boats. It is located in the eastern part of Slateport City, and is where the S.S. Tidal was constructed. The Shipyard also takes old boats and sinks them, to make habitats for the Pokémon who live around the city and its neighboring beaches.
When the player first arrives in Slateport the Oceanic Museum will be inaccessible. The player must first talk to Dock on the first floor of the Shipyard, and then head to the Museum to meet Captain Stern.
