"The first of three lavish cruising yachts in this series is scheduled to take to sea in the fourth quarter of 2019, and distinguishes Marriott International as the only provider of luxury accommodations both on land and at sea. “This unique combination of yachting and cruising will usher in a new way of luxury travel for guests seeking to discover the world in a relaxed, casually elegant and comfortable atmosphere with the highest level of personalized service.”

Itineraries are being developed with an intent to combine the lifestyle of The Ritz-Carlton’s luxury resorts and the casual freedom of a yachting vacation. Calling at intimate and signature destinations alike, voyages will range from seven to ten days. The first ship will cruise a wide variety of destinations depending on the season, including the Mediterranean, Northern Europe, the Caribbean and Latin America. Due to the intimate size of the vessel, the yacht will call at unique locations typically not accessible to large cruise ships, from Capri and Portofino to St. Barths and the old town of Cartagena. With a relaxed pace, that includes both overnight and daytime ports of call, guests will be offered a uniquely curated destination experience."
