Shipyard

The Shipyard is a location in Phantom Hourglass and Skyward Sword.

Phantom Hourglass
Located in Mercay Island, the Shipyard is where Link can go to customize the S.S. Linebeck with the various Ship Parts he has found throughout his adventure. Moreover, he can also talk to the Shipyard Worker to repair the Salvage Arm: the more damaged the Salvage Arm is, the more he will charge, with the maximum fee being 100 Rupees. However, the shipyard worker does not charge for customizing Link's ship.

Link can obtain a free Ship Part by opening the treasure chest inside the Shipyard.

Skyward Sword
The Lanayru Shipyard in SS undefined, located in the Lanayru Sand Sea, was an ancient sea town inhabited by the workers who built the ships inside the construction bay. Link and Skipper visit the Shipyard after Skipper's Retreat in their search for Skipper's lost ship, which was among those constructed there. Each of the areas on the island are connected to each other via a complex series of mine-cart tracks. The door leading to the construction bay where Skipper thinks his clues leading to his ship may be is closed, forcing Link to ride mine-carts on the tracks around the Shipyard to access the back door.

When Link arrives in the construction bay, he uses his Gust Bellows to search the massive sand deposit. Rather than find clues pertaining to the location of the ship, he mistakenly awakens a buried Moldarach, which had moved in and built a nest in the many years that the factory went unused.

After returning to Skipper through the door that was previously locked, they sail on towards the Pirate Stronghold.

Rickety Coaster
The Rickety Coaster is a mine-cart mini-game run by the Goron named Gortram on the tracks sprawling around the construction bay. The mini-game comes in two difficulties, "Scary" and "Heart Stopping!". If he completes the "Heart Stopping!" track in less than the time of 1.05.00, Link will be rewarded with a Piece of Heart. The mini-game is operable after the Sandship is returned to Skipper.

Trivia

 * The Bridge Worker from Spirit Tracks bears the same physical traits as the Shipyard Worker. He has also portrait of the Shipyard Worker in his house. This suggest that the Bridge Worker may be a descendant of the Shipyard Worker.
 * At no real point can Link ever see the crane that hangs over the water.
