Sail

The Sail is an item in.

Location and Uses
The Sail can be purchased from Zunari on Windfall Island for 80 Rupees. It allows Link to catch prevailing winds to sail from island to island. It can only be used while onboard the King of Red Lions. If the Sail is used in an area with no wind, it will have no effect on the King of Red Lions. In, the Sail is a quest item instead of a regular item, eliminating the need to assign it to a button to deploy it.

Swift Sail
In, the Sail can be upgraded to the Swift Sail, which enables the King of Red Lions to sail faster. It also automatically changes the direction of the wind to where the boat is heading. This eliminates the need to conduct the "Wind's Requiem" when sailing. The Swift Sail is activated by pressing the A Button while the normal Sail is deployed, and can be changed back to the normal Sail by pressing A again.

The Swift Sail can be found at the Auction House on Windfall Island after completing Dragon Roost Cavern.

Hyrule Warriors Series
In, the Sail is a class of Weapon used by King Daphnes. It is associated with Water. It allows King Daphnes to transform into the King of Red Lions as part of his moveset.

Variations
The default Sail is the Windfall Sail. The second form of the Sail is the Swift Sail, followed by the Sail of Red Lions.

In Hyrule Warriors Legends only, the fourth form of the Sail is the Supercharged Sail, which is associated with both the Elements of Water and Lightning.

Special Attack
King Daphnes summons a huge tidal wave beneath him, gaining altitude with it. Once it gains enough altitude, he transforms into the King of Red Lions and pushes the wave forward, smashing enemies in front of him caught by the water. This attack hits enemies in a rectangular pattern in front of Kind Daphnes.

Trivia

 * According to Eiji Aonuma, the Swift Sail was added to the game thanks to the superior processing power of the Wii U, which can load the entire Great Sea at once.
