Someone on the ferry heard the loud noise of the foghorn, and at the last minute the ferry changed course. The green starboard light of the big ship disappeared and its high black sides went quickly past the Goblin. Show your lights, you stupid fishermen, came an angry voice from a loudspeaker above, and then the ferry had passed them and was off on its way to Harwich. The Goblin, and everyone in it, was thrown from side to side in the big waves made by the ferry, but they were still in one piece.
