The S.S. Tidal (Japanese: タイドリップごう S.S. Tiderip) is a ferry from the Hoenn region, featured in Pokémon Ruby, Sapphire, and Emerald. Its captain is Mr. Briney.
The S.S. Tidal transports players from one location to another. Its main voyage takes players from Lilycove City to Slateport City and vice versa, but other tickets allow other locations to be reached. The tickets available vary depending on the game. Only one can be obtained in-game: the S.S. Ticket, which leads to a special area after the Elite Four has been defeated. The rest must be obtained in a Nintendo event, but all give access to an island where a legendary Pokémon awaits capture.
Like Johto's S.S. Aqua, there are many Trainers on board the ship that can be battled on the journey—but only once. Each of them can be found in their own cabin. The player also has a cabin. If the player sleeps in the bed in this room, the ship will arrive at its destination.
Hall
The hall is the main part of the S.S. Tidal. When the player first enters, they start off near the entrance staircase, on the far south-western corner of the ship. There are eight cabins in the middle of the hall. On the north-eastern corner of the ship, there is a staircase down to the basement. There are portholes located on the northern side of the ship, which the player can look out them and see their current location, whether they are traveling against the currents of Route 133, or traveling over the seas to the Battle Tower. Mr. Briney and Peeko are also located on the northern hall, where they will welcome the player the ship.
Cabins
In total, there are eight cabins holding the ship's passengers. Some of them will battle, and some will not. In one room there is a man standing next to a bin who gives away TM49 (Snatch). The player also has his or her own cabin. If the player sleeps in the bed in this room, the ship will arrive at its destination.
Basement
On the north-eastern corner of the ship, there is a staircase down to the basement of the S.S. Tidal. Down in the basement are several of the ship's crewmen taking a break or training with their Pokémon. The basement contains giant cargo containers that are located around the room. Two sailors are roaming around the room, ready for a battle. The item Leftovers is hidden in one of the three trash cans located around the room.
