Tetra's Ship is a large, one-masted vessel with a single square sail that belongs to Tetra and her pirate crew. It plays a significant role in Link's adventures in The Wind Waker and Phantom Hourglass. Throughout the former, it is briefly used as transportation across the Great Sea as well as an occasional venue for acquiring new items by completing challenges.
The Wind Waker
In The Wind Waker, Tetra's ship makes an appearance very early in the game. It is seen pursuing the Helmaroc King, with Tetra gripped in its talons. The pirates use a large boulder fired from a catapult to attack the bird, causing it to drop Tetra on the summit of Outset Island's mountain. After being rescued by Link, Tetra returns to her ship, which had at this point docked at Outset. After some convincing from Quill the postman, she agrees to take Link to the Forsaken Fortress on board her ship.
During the long voyage, Link is sent below-decks to see Niko, the lowest-ranking member of the crew. After Link completes his rope-swinging obstacle course, Niko gives Link the Spoils Bag. Upon their arrival at the fortress, Link is catapulted inside in a Barrel. Tetra's ship remains hidden behind a large rock while the pirates wait for Link. When they see Link being tossed into the sea by the Helmaroc King, the pirates presumably fled, mistakenly assuming that Link had drowned.
Later in the adventure, Link arrives at Greatfish Isle, now cursed. Quill arrives to tell Link that Tetra's crew is seeking Nayru's Pearl, and the pirate ship is docked at Windfall Island. Link sails to Windfall, where the pirates are in the process of robbing the bomb shop. Link sneaks aboard their ship and steals a bomb bag to use at Outset Island.
After the final battle with Ganon, Hyrule Castle floods, sending Link and Tetra back to the surface, where they are rescued by Tetra's loyal crew. They are pulled out of the water onto the deck of Tetra's ship.
A map found in Tetra's room shows the three Triangle Islands, Dragon Roost Island, Forest Haven and Greatfish Isle connected by lines forming a Triforce around the Tower of the Gods. This, along with Tetra's search for Nayru's Pearl and her disbelief of Link possessing the Master Sword make some believe that the "legendary treasure" she is seeking is an artifact found in Hyrule Castle, possibly the Master Sword.
Other pieces found in her cabin include a portrait of Tetra's Mother and two pieces depicting the Hero of Time and Hyrule as they appear in the opening cutscene. If Link speaks to Senza when they set out for sea, he will tell the young hero that he's seen a picture of someone wearing the same Green Clothes that Link wears in Tetra's cabin.
In Phantom Hourglass, Tetra's ship is only seen in the opening and closing cutscenes. It is explained that Link joined the pirate crew after the events of The Wind Waker, and set sail with Tetra in search of "new lands." At the end of the game, Link and Tetra get back on board the pirate ship, and it is assumed that they set sail for more adventure.
