Triforce Shard 5
Triforce Chart 3 (Wii U) / Triforce Chart 5 (GameCube) (A-5) / Triforce Shard (#5)
Locations: Needle Rock Isle, Cliff Plateau Isles
The number of the Triforce Chart varies between versions (3 for Wii U, 5 for GameCube), but the quest is the same:
Make your way to square A-5: Needle Rock Isle, on the map. Look for a group of gunboats patrolling the waters northwest of Needle Rock Isle. One of the boats is golden.
Destroy the ship and immediately use your salvage crane to retrieve a treasure (now sunken) that was loaded on the boat. You can use the orb that remained when you blew up the ship as a locator -- or sail away and turn around to see a glowing spot where you need to look for the chest. You will get your hands on the Treasure Chart 3 (or Triforce Chart 5, in the GameCube original).
Travel to location G-6: Cliff Plateau Isles. The Triforce is hidden in the spot shown above. Use Triforce Chart 3 (GCN: 5) to track it down and salvage it with your utility crane.
