The S. S. Linebeck is the boat that Link, Ciela and Linebeck use to travel the Sea in Phantom Hourglass. It originally belonged to Linebeck but he agreed to help Link in his quest by letting him travel on the ship.
Template:Spoiler In the end, when Link defeated Bellum and the ship had sinked, the Ocean King granted Linebeck one wish, and, surprising everybody, Linbeck wished to get his boat back. When Link and Tetra awake at the Ghost Ship, Link sees Linebeck's ship floating away in the end. Bold text
