The Wraith is the swift, beautiful, and distinctive red and gold ship in the shape of a bird manned by Ren, Ioz, Tula, and Niddler. Its bowsprit even resembles the head and beak of a bird, the sail resembles a pair of wings (and can be detached to become a glider), and the decorative wooden frill on the aft end of the boat looks like a tail. This ship doesn't actually belong to the crew; instead, it belongs to a vicious pirate named Joat. Knowing that it was one of the fastest, if not the fastest, vessel in existence, Ioz sneakily posted advertising flyers around the town where it and he currently were, claiming that he had a ship for rent. Ren and Niddler found one of the fliers and met to do business with Ioz, not finding out until after they set sail that the ship wasn't theirs. As a result of Ioz's thievery, Joat soon became the laughingstock of the twenty seas, and he tried to reclaim the Wraith, but to no avail.
According to the Series Bible, "This vessel is a mix of 14th century technology and that of the ecologically based Merian maritime civilization....The Wraith is a character in its own right. Cut from mystical trees on a remote island, the lumber used in its creation maintains its life force. At times it may seem to be haunted, at other times it may seem to have a mind of its own. And until Ren and the crew decipher the mysterious carvings in the wraith’s decking, they are often at the mercy of the boat’s capricious spirit."
