If you get the In-credible chart from Tingle, it'll show you all the locations of the charts. When you've found one at it's designated spot, pay Tingle at the Tingle tower 398 ruppes/chart (You will need the giant Ruppee bag) and he will mark the location on your In-credible chart.
You will need to find the 8 Triforce charts. Be using the Incredible chart, it will tell you where each chart is located. After you collect and decipher a triforce chart, you can check it or the incredible chart to find the location of the Triforce Shard. You will then have to sail, or teleport and salvage the chest with the grappling hook.
It is just off of the dock, but if you have the TRIFORCE CHART, the area that the triforce peice is will be lit up when you open the treasure chart.
#1 you dont get the triforce chart from the ghostship, you get it from the big hole with the head covering it on outset island, search my posts, i discussed it in a previous post
Tingle charges 398 ruppees to translate a triforce chart so save up about 3190 for him to read all of them
If you mean the last triforce shard, you have to find it on the sea maps after getting them translated by Tingle. If you mean how you get the last part of the Triforce (the Triforce of Power), you can't. Ganondorf has it, and you're not supposed to get it.
to get the triforce chart first go to the far left hand side of the map on of those island has a chart on it in a cave then once you get it go to one of the islands on the map when the moon coressponds with that island then when you see it ram it
put the triforce simbol on that red door and the continue and find it
The last symbol is the triforce
You need to obtain Triforce Chart # 2 from the Private Oasis first. Then use the grappling hook like finding any other treasure in the Great Ocean.
1. there are several triforce shards, so not 1 but 8. 2. the shards aren't on any island, the CHARTS are on islands, wich 2 of them are actually a gunship and a ghost ship. 3. Go get the IN-credible Chart from your postbox. Fairy on the north fairy isle gives you a bigger wallet so you can afford its price. wich is 201 rupees. On the chart are the locations of all triforce charts. oh, and free Tingle from his prison in windfall before anything.
You can't........humanly.
The Triforce shards are hidden in the ocean. To find them you must have the Triforce Charts which will tell you where to find them in the ocean. When you have a chart and find the specific area it asks you to find, you can then reach into the ocean and retrieve it. Here is a very informative guide to finding all eight Triforce shards: http://www.gamefaqs.com/gamecube/469050-the-legend-of-zelda-the-wind-waker/faqs/42707
