On the early watch, a colourless sun turns the shifting waves to a runway of dynamic molten silver. At dusk, as the light leaches away, the sea turns pewter, then gun-metal grey, the wave surfaces etched and chiselled and constantly in motion. At night, there’s an immensity of stars, silent above the black sea. It’s the biggest space I’ve ever been in. It’s extraordinarily, exhilaratingly, utterly wonderful. And I suspect, as I notice my distinctly mixed reactions to the news that we might reach land tomorrow, addictive.
