S. S. Linebeck
From Zelda Wiki.org
The S. S. Linebeck is the boat that Link, Ciela and Linebeck use to travel the Great Sea in Phantom Hourglass. It originally belongs to Linebeck but he agrees to help Link in his quest by letting him travel on the ship. Ship Parts can be collected to customize it. Other updates to the ship are the cannon and Salvage Arm.
When at sea, the ship's endurance meter appears as Green Hearts on the screen. Docking the ship replenishes any hearts lost during travels. The Salvage Arm however must be repaired on Mercay Island. The ship yard on Mercay Island is also a hub to customize the ship.
Spoiler warning: The following contains key plot or ending details.
In the end, when Link defeats Bellum and the ship has sunk, the Ocean King grants Linebeck one wish, and, surprising everybody, Linebeck wishes to get his boat back, rather than treasure. When Link and Tetra awake on the Ghost Ship, Link sees Linebeck's ship sailing away in the end.
