The Vessel

Built for the bay, not for the brochure

Diana was delivered in October 2025 on a double hull from the Damen yard — the same construction standard used for vessels working the North Sea. She is classed VR-SI, rated for two-metre seas and force-eight wind, which in Ha Long means she keeps her schedule when lighter boats do not.

Ninety-five metres long and fifteen and a half wide, she carries fifty-six cabins across three accommodation decks and four more decks of public space: restaurant, lounge, pool, spa, gym, golf and an open rooftop. Two lifts run from Deck 1 to Deck 5.

Every cabin has a private balcony. Every cabin has Starlink internet. There is no inside cabin on this ship.
