The Coast of Adventure by Harold Bindloss

There had been wind, but it had fallen toward evening, and the _Enchantress_ rolled in a flat calm when her engines stopped. As she swung with the smooth undulations, blocks clattered, booms groaned, and the water in her bilges swirled noisily to and fro. It was difficult to move about the slanted deck, and two dark-skinned, barefooted seamen were seated forward with their backs against the rail. A comrade below was watching the engine fires and, with the exception of her Spanish helmsman, this was all the paid crew the _Enchantress_ carried.

She drifted east with the Gulf Stream. Around her there hung a muggy atmosphere pervaded with a curious, hothouse smell. Grahame stood in the channels, heaving the lead. He found deep water, but white patches on the northern horizon, where the expanse of sea was broken by spouts of foam, marked a chain of reefs and keys that rose a foot or two above the surface. A larger streak of white was fading into the haze astern, but Grahame had carefully taken its compass bearings, because dusk, which comes suddenly in the Bahama Channel, was not far away. He dropped the lead on deck, and joined Macallister, who stood in the engine-room doorway rubbing his hands with cotton waste.
