O.J. (an abbreviation of "Old Jones") is Captain Star's third and oldest tug. He is indeed capable of a variety of tasks, but is sometimes restricted by his age and mechanical condition. However at the end of the episode Quarantine, he was taken to Lucky's Yard to receive a new engine and the problem was resolved. He speaks with a South Welsh accent O.J. is the only paddle-driven tug left in Bigg City Port. He can be described as slow, but versatile. As Captain Star once said in Quarantine, "He'd given many years of good service, but time was catching up on him." Prior to an overhaul during the Year of the Heat Wave, O.J.'s aged engine was the cause for a number of mishaps, including an accident that resulted in the sinking of the Fultan Ferry. O.J.'s weakness and age has often placed him on the receiving end of jokes and insults from the Star Fleet and Z-Stacks alike (mostly the Z-Stacks and Top Hat). For a period, he was the primary target of Burke and Blair, the evil-minded scrap dealers who attempted on a number of occasions to persuade Captain Star into selling O.J. and his engine for a cheap price. But after O.J.'s quick thinking prevented Ten Cents from having to enter quarantine, Captain Star sent O.J. to Lucky's Yard and the scavengers on their way.
