Captain Barnaby is an old sea captain who takes players from East Ardougne to Brimhaven by his ship. His toll is 30 coins, similar to all other ships to and from Karamja.
This toll can be reduced to 15 coins by owning any form of Karamja gloves, obtained from the Karamja achievements. Players can also get a free ride back and forth from Brimhaven from Barnaby by wearing a ring of charos (a).
During My Arm's Big Adventure he takes the player and My Arm to Karamja, After they have finished the quest, he'll start the conversation with: "Oh no, it's you again!"
