The Ritz-Carlton Yacht Collection Ritz-Carlton kicked off the craze for luxury-hotel-owned cruises with the launch of its 624-foot-long Evrima in 2022.It was a triumphant test for the business model, with few availabilities during its first year in service.It's easy to see why. Evrima offers a transverse marina that opens onto the water, an infinity pool, a cigar lounge, and an almost one-to-one guest-to-staff ratio. Its five eateries include a European-inspired tasting menu for a fee. The menu was designed by the chef of Aqua, a restaurant with three Michelin stars in Ritz-Carlton's Wolfsburg, Germany, hotel.

"People were very favorable for us to pursue a Four Seasons experience at sea," he added.The company tapped Fincantieri to build the 34,000-gross-ton vessel.
