The 180-guest vessel features a three-tier atrium and a heated swimming pool that transforms into a cinema, as well as a range of suites and staterooms.
David Winterton, global director of brand and marketing at Emerald Cruises, said the vessel marks a "new, exciting addition to our growing fleet".
"While bookings remain strong for this spring and summer, and with Europe continuing to be a popular destination for both new-to-cruise and loyal guests, the launch of Emerald Luna allows more opportunity for our trusted agent partners to sell experiences on Europe’s rivers in our signature Emerald Cruises style," he added.
A christening ceremony for Luna will be held in Amsterdam on 21 July, attended by godmother Vanessa McGovern from Gifted Travel Network.
