Waterhouse first sees Outer Qwghlm through a scupper. He doesn’t even know what a scupper is, except a modality of vomiting. The ferry crew gave him and the other half-dozen passengers detailed vomiting instructions before they fought past the Utter Maurby breakwater, the salient point being that if you leaned over the rail, you would almost certainly be swept overboard. Much better to get down on all fours and aim at a scupper. But half the time when Waterhouse peers down one of these, he sees not water but some distant point on the horizon, or seagulls chasing the ferry, or the distinctive three-pronged silhouette of Outer Qwghlm.
