Morning breaks gently in West Papua. After a breakfast of spicy curry and unfamiliar fruits, guests step onto a skiff loaded with paddleboards and dry bags, then skim across glassy waters toward Pianemo, an archipelago of limestone dollops rising straight from the sea, their sides swaddled in dense jungle. With every paddle stroke, the color beneath shifts from cerulean to teal to aquamarine — so clear that coral heads and darting fish appear suspended in midair.

The channel narrows, spilling into a freshwater swimming hole as cold and pristine as New Zealand’s Blue Lake.

In the middle of the Western Pacific, the only witnesses are two locals in feathered crowns and grass skirts, their faces painted, their smartphones discreetly stealing photos.

This is Raja Ampat, a 15,000-square-mile refuge in Indonesia’s far eastern reaches, where, unless you arrive by boat, you can’t really arrive at all. The region’s hundreds of jungle-draped islands and razor-thin straits are largely inaccessible by land or cruise ship. The most elegant way to reach this destination is aboard Dunia Baru, a 167-foot wooden phinisi modeled on the hand-built trading vessels that once ruled this region of the Spice Route. On board, the journey isn’t a means to an end; it’s the entire point.

Viewed from Pianemo’s waters, Dunia Baru cuts a cinematic figure, something out of “Pirates of the Caribbean: Asia Edition.” Its long ironwood hull sways among gentle swells. Two towering masts carry seven curtain-like sails that unfurl sideways along the horizon, not hoisted vertically like Western schooners.

This ingenious design, perfected in the 14th century by traders aiming to counter fierce island winds, allows the ship to slip through narrow passages in the molten-blue waters of the Coral Triangle. The sharply pointed bow and lean profile allow the yacht to nose into lagoons and anchorages that larger ships simply can’t reach. It’s not uncommon to go days without spying another vessel in the distance.

And that’s as it should be here, in one of the most bio-diverse places on Earth. Raja Ampat is home to 75 percent of the world’s coral species, more than 1,500 types of fish, six of the seven sea turtles, reef sharks, manta rays and the adorable pink pygmy seahorse, which looks less like a real animal and more like something out of a child’s imagination.

But getting here is a commitment. From New York, it takes at least three flights, 40 hours and severe jet lag. Once travelers arrive in West Papua, most alight bare-bones liveaboards, bunking shoulder to shoulder for weeks. Dunia Baru offers another reality entirely.

The yacht was conceived by American adventurer Mark Robba, who spent eight years overseeing an obsessive re-creation of a Bugis phinisi, vessels traditionally built from whole trunks of ulin, a nearly indestructible hardwood now protected by the Indonesian government.

He enlisted fifth-generation Konjo shipwrights from Sulawesi to build the yacht entirely by hand, without nails or metal.

The result, completed in 2014, was a masterpiece few experienced until Singapore-based entrepreneur Jing-Yi Wee and her brother purchased Dunia Baru and refitted the ship for ultraprivate charters.

The siblings refreshed the interiors with Indonesian textiles and custom upholstery while preserving the ironwood skeleton and iconic sails.

The Wees describe the yacht as an “inventory of one,” and that’s not marketing hyperbole. Another will likely never be built again, since the craftsmanship is disappearing, the wood can no longer be harvested and building the thing cost around $10 million.

Today, Dunia Baru’s 18 crew members welcome a maximum of 14 passengers across seven suites with cold towels and a request to kindly remove shoes. For the rest of the week, it’s barefoot luxury from bow to stern.

The primary suite commands sweeping ocean views, a private terrace for reading and massages, and a deep daybed ideal for stargazing or sunrise coffee. Six additional cabins line the lower deck, each wrapped in teak, cooled by whisper-quiet air circulation and scented by wood and sea.

Life aboard quickly settles into an effortless rhythm. Mornings might begin with yoga on the foredeck as gear is prepped. Divers descend into coral cities patrolled by reef sharks and manta rays, responsibly cruising through a nat-ural “cleaning station,” while non-divers snorkel in lagoons so vivid they look CGI’d. Between swims, the crew appears with smoothies and fresh towels.

Afternoons remain gloriously optional. Kayak through jade-green lagoons. Paddleboard beneath towering karsts. A tender shuttles guests ashore for jungle picnics or surprise beach bonfire lunches. Back on board, there’s reading, sunbathing, naps and long lunches — often a Balinese seafood barbecue, enjoyed in swimsuits. After dark, dinner unfolds beneath the stars: freshly caught fish seared with lime and chili, family-style spreads, flowing cocktails. Maybe even an unexpected fireworks display on a nearby spit of sand.

Raja Ampat may be the main destination, but luxurious access is what Dunia Baru truly offers — to a place too wild, too fragmented and too far-flung to be seen any other way. It delivers time, solitude and immersion into a beauty so foreign and so intact, it’s worth the maddening jet lag.

Sailing aboard reminds travelers that, in an era obsessed with accumulation, the greatest luxury is drifting slowly through something that remains, against all odds, miraculously untouched.
