Royal Caribbean has announced that Legend of the Seas has reached a major construction milestone by beginning sea trials in Turku, Finland. The ship is now in the open water for technical testing, with the work expected to continue over the next 10 days as part of preparations for its July 2026 debut.

Sea trials are one of the final stages in a ship’s build process. During this phase, the vessel undergoes technical examinations to check performance, safety systems, and overall readiness before entering service. Royal Caribbean says this testing is taking place ahead of the ship’s highly anticipated European debut this summer.

Sea trials are a strong sign that a new ship is moving closer to delivery and launch. They usually indicate that major construction work has been completed and that the focus has shifted to operational checks at sea. In this case, Royal Caribbean is preparing the ship for a July 2026 debut, making the current testing phase especially important for the timeline.
