Built for the bay
She keeps her schedule when others cannot
Diana was delivered in October 2025 on a double hull from the Damen shipyard, and is classed VR-SI for two-metre seas and force-eight wind — which in Ha Long means she sails in conditions that keep lighter boats in harbour.
Ninety-five metres long and fifteen and a half wide, she carries fifty-six suites across three accommodation decks, with four more decks of public space above: restaurant, lounge, pool, spa, gym, golf and an open rooftop. Two lifts run from the 1st to the 5th deck.
Every suite has a private balcony or terrace, and Starlink internet. There is no inside cabin on this ship.
