River cruising remains one of the fastest-growing segments of the cruise industry, with operators continuing to expand fleets in response to strong demand, particularly in Europe. The latest sign of that momentum came from TUI River Cruises, which has announced two newbuild vessels designed for next-generation operations using methanol-ready technology.
The two newly ordered vessels were announced on March 30, 2026, during the christening of TUI Aria in Frankfurt. According to TUI Group, the ships will expand the company’s river cruise fleet from six vessels in 2026 to 10 ships by 2028, operating across Europe as well as the Nile and the Douro.
Each of the new vessels will feature 94 cabins and carry up to 188 passengers. TUI said the ships are being purpose-built for the UK market, reflecting the company’s strategy of targeting British travelers with fly-cruise products on Europe’s most popular rivers.
The announcement also highlights the rapid growth of TUI’s river cruise business. The company first revealed plans to enter the sector in 2019, but its launch was delayed until 2021 because of the pandemic. Since then, TUI says the brand has grown strongly, with sales up by 50% year on year by 2026.
TUI’s latest expansion comes as the wider river cruise market continues to build momentum. Viking, one of the sector’s largest operators, said earlier this month that it expects to take delivery of 22 additional river ships by 2028, which would bring its river fleet to 112 vessels.
Another emerging player, Transcend Cruises, has also moved to scale up quickly. The company recently announced two additional river ships, which will expand its planned fleet to four vessels by 2028. Its first ship, Connect, is expected to begin service in July 2026, while Evolve is scheduled to follow in 2027. The newly ordered ships, Create and Engage, are due for delivery in October 2027 and early 2028.
Transcend is targeting the group and charter market, and its vessels are designed with a flexible layout that allows cabins to be converted into larger suite-style configurations. That strategy reflects a broader trend in river cruising, where operators are increasingly focusing on customization, premium experiences, and more efficient use of onboard space. This last point is an industry inference based on the design features and fleet announcements.
The latest orders show that river cruising is no longer just a niche extension of the ocean cruise market. Operators are investing in cleaner propulsion, modern vessel design, and larger fleets as they respond to growing interest in experience-driven travel built around scenery, culture, and smaller-scale itineraries. With TUI moving into methanol-ready ships and other brands accelerating expansion plans, the sector appears set for continued strong growth over the next several years.
