4:07 p.m.: It’s the colors that strike you first. Above your rattan lounge chair on Tiger Blue, a wooden schooner sailing through Indonesia’s West Papua province, blood-red sails billow against the sky. Luminous green forests seem to glow on shore. All around, the water glistens azure, turquoise, and, in the shallows, a pale crystalline aquamarine. You’ve already hiked island slopes and snorkeled with sea turtles and manta rays, so perhaps it’s time for a nap in a shaded hammock? This evening, you’ll moor alongside a sheltered beach for a lobster barbecue; later, though there are four spacious cabins aboard, you might sleep on linen-covered cushions under the stars. And why not? Other than the crew, there’s no one to disturb you for miles.
