The three ships will build on the momentum from launching four new vessels Uniworld next year. Ellen Bettridge, Uniworld Boutique River Cruises President and Chief Executive, said: "This is one of the most significant periods of investment and growth in Uniworld's history.
"As demand for immersive travel continues to grow, every new ship we build allows us to continue raising the bar for luxury river cruising. It's also an opportunity to create deeper, more meaningful connections between our guests and the destinations we sail.”
Uniworld's Helen ship will "embrace the philosophy of Mediterranean elegance" when it launches on the Danube. Among its featured itineraries is the 15-day Danube Grandeur sailing where guests will sail through six countries. Prices for the 28 October departure start from £5,549 per person.
Joining Uniworld's Rhine fleet, the Clara ship honours 17th-century Flemish painter Clara Peeters, one of the Dutch Golden Age's most celebrated female artists.
It will debut with an eight-day Holland & Belgium at Tulip Time itinerary departing on 31 March 2028 with fares leading in from £3,349pp.
Mekong Mystique will expand Uniworld's footprint in south-east Asia operating alongside the existing Mekong Jewel.
