The 207-metre Four Seasons “yacht liner”, Four Seasons I, has officially entered service, completing her maiden voyage in the Mediterranean and marking the brand’s long-anticipated debut in the luxury yachting sector.
The 95-suite vessel, built by Italian shipyard Fincantieri, represents a new category of “yacht liner”, blending superyacht design with cruise-scale amenities. First revealed as a concept in 2023, the project has now transitioned from design to operation, with Mediterranean itineraries already underway.
Purpose-built around the guest experience, the vessel offers an all-suite, residential-style layout with no interior cabins - many featuring expansive terraces and private plunge pools. A near one-to-one guest-to-staff ratio underpins the Four Seasons hospitality model at sea, extending the brand’s service-led approach into a maritime setting.
Design comes from Tillberg Design of Sweden, part of The Viken Group, with public spaces by Martin Brudnizki Design Studio and creative direction from Prosper Assouline. The design references the golden age of yachting, drawing inspiration from Canadian Vickers' 99.1-metre classic Christina O while incorporating contemporary elements such as floor-to-ceiling glazing and expansive indoor-outdoor living areas.

A standout feature is the transverse marina, which opens across both sides of the vessel to create a sea-level platform for watersports and guest access.
Operationally, the yacht is supported by Anglo-Eastern Cruise Management Inc. (AECMI), which has been involved since the build phase at Fincantieri’s Ancona facility. Its remit spans technical management, regulatory compliance and crew recruitment and training, alongside shoreside services such as fuel procurement, itinerary support and voyage monitoring.
According to AECMI, the vessel’s highly customised design required tailored operational procedures, particularly for tender operations, side shell doors and marina deployment, supported by a bespoke safety management system developed in coordination with Transport Malta and classification partners.
The yacht’s inaugural voyage, which departed on 20 March, coincided with the 65th anniversary of Four Seasons, marking a symbolic milestone as the brand expands from land-based hospitality into yachting. Mediterranean itineraries will be followed by Caribbean and Bahamas seasons, with a total of 52 sailings planned across 130 destinations in the first year.
The project forms part of a wider fleet strategy, with a second vessel already scheduled for delivery in 2027.
