Galleon is a stage in Tekken 5: Dark Resurrection corresponding to Pirate's Cove in Tekken 5. The differences between this stage and its Tekken 5 counterpart is that this stage is actually set on a ship. The skeletons, treasure chests and the steering wheels are still seen. The amount of gold seems to be in even larger piles here as well.
The stage BGM is named "Tiamat".
