From the Super Mario Wiki
Wario Shipyard (known as Wario's Galleon in Europe and Australia) is the second of the Star Cup in Mario Kart 7. The course is owned by Wario and takes place inside of a sunken ship in a stormy weather.
The course is mostly underwater. It includes swinging anchors and broken remains of the ship. There are several ramps for players to execute tricks or collect coins. The floors and giant pipes create jet streams providing players to a higher position. Upon reaching the finish lap, players must glide while avoiding obstacles such as the ship's topsails and anchors. Minecarts filled with gold, likely based to Wario's Gold Mine can be seen just as the player boards the ship itself.
The music track of this course is based on the main theme of Wario Land: Super Mario Land 3. The course is possibly an homage, as the game had a pirate theme. In fact, Bull Wario (a form from that game) can be seen in one of the course's billboards.
 Course layout
The course starts in a dry chamber. After a short straight path there's a left turn leading the player to an underwater area divided into two roads, one rising off the pond. After some ramps, the racers enter a short tunnel styled as a giant Fishbone (some Fishbones swim through this tunnel on the second lap). On the other side of it, there are water streams coming out of Warp Pipes. A huge pipe blows the karts up to the next area of the circuit.
The next road features a mud pit, complete with ship masts and a Barrel, which releases an item upon contact. A swinging anchor is found just before a shipyard. The road splits into two short paths. As they merge again, the players should avoid two Sidesteppers and barrels.
A glider ramp takes the racers to a big area above the lake, where they should avoid hitting topsails and anchors. This area is followed by two roads: the higher one containing coins and Boost Pads, while the lower one being empty. The finish line is set right after both roads merge into one.
