Great Cruise Journeys will work in partnership with AMA and Travelmarvel and will travel to destinations including Austria, France, Germany and Hungary.
The launch collection will feature eight holidays including premium and luxury cruises on the Danube, Douro, Main, Rhine and Rhone. Prices start from £1,195 pp for the eight-day Rhine and Main cruise.
The tour operation will also charter the Spirit of Chartwell on the Douro River.
Alex Roberts, group marketing and sales director at Great Rail Journeys, said: “Following the ongoing success of our escorted group rail and cruise programme, offering independent cruise holidays to our existing customers was a natural extension.
"Early sales have been extremely positive and we are excited about the prospects and opportunities for the brand.”
Great Cruise Journeys plans to expand the portfolio for 2018 departures to further explore Europe’s waterways.
