Four Seasons Yachts has completed the first sea trials of Four Seasons I, advancing the project toward its inaugural season. The trials were conducted over five days off the coast of Ancona, Italy, near the shipyard where the vessel is under construction, and represent a key technical phase ahead of launch.
According to the company, the trials involved more than 60 separate evaluations covering propulsion, navigation, mechanical and electrical systems, safety, environmental performance, and onboard comfort. The program concluded with a six-hour endurance run at full power, designed to confirm operational stability and overall seaworthiness. The results verified that the vessel meets the required performance and reliability benchmarks for its class.
In parallel with technical testing, the sea trials also focused on guest-facing conditions across suites and public areas. Assessments included vibration and noise levels, climate control systems, and overall onboard comfort—factors that are central to the yacht’s operational readiness ahead of service. These checks are intended to ensure consistency across accommodations and shared spaces once the vessel enters active operation.
“The results of these trials speak to the level of craftsmanship and technical rigour behind Four Seasons I,” said Ben Trodd, the CEO of Four Seasons Yachts. “Seeing the yacht perform as intended gives us real confidence as we move into the final stages ahead of welcoming our first guests.”
Four Seasons I is being built in Italy, a country with a long-established shipbuilding tradition and a concentration of specialist maritime engineering expertise. Ancona, in particular, is home to several large-scale yards involved in the construction of complex passenger vessels, including expedition ships and custom yachts. The location allows for immediate access to open-water testing in the Adriatic Sea, streamlining trial operations during the build process.
The completion of the first sea trials marks the end of an initial verification phase. A second round of sea trials is planned later this month, during which additional systems will be tested as the vessel moves closer to final delivery. These subsequent trials are expected to focus on further operational checks and refinements ahead of launch.
Following the completion of the upcoming trials, Four Seasons I will enter the final preparation period before its inaugural season.
