Uniworld Boutique River Cruises announces the debut of three new ships in 2028: the S.S. Helen, S.S. Clara, and the Mekong Mystique, bringing the brand’s total fleet size to 22. The added vessels further elevate Uniworld’s signature boutique river cruise experience across the Danube, Rhine and Mekong rivers, each drawing inspiration from the art, history and culture of the region it sails in. The announcement builds on the momentum of the brand’s recent fleet expansion, with four new ships joining the Uniworld fleet in 2027.
