Over two decades since their first Antarctic air-cruise expedition, Antartic21 continues ahead towards the future of Antarctic exploration with Magellan Discoverer, their most ambitious endeavor to date. Currently under construction at the ASENAV shipyard in Valdivia, Chile, and set to launch in December 2026, this state-of-the-art polar vessel represents the culmination of over 20 years of Antarctica21’s experience and innovation. They are pleased to share the latest update on this exciting project.

Construction Milestones

The hull blocks are now fully assembled. All the steel superstructure components have been fabricated, and 95% have been constructed. The diagram below provides a visual reference of the construction progress.

On October 24, 2025, the ceremonial float-out of Magellan Discoverer was proudly marked at the ASENAV shipyard in Valdivia, Chile. It was a moment filled with pride and emotion, one that they were excited to share through this video.

Following its successful launch, Magellan Discoverer has entered the final stages of construction. All the ship’s essential systems, ranging from advanced navigation and stabilizers to control panels, doors, and ventilation, have now been installed. Work is also progressing steadily on the vessel’s piping and electrical systems, while interior outfitting is advancing, with cabin and public space furnishings entering the final stages of procurement.

During the upcoming months, work will continue focusing on interior outfitting, integration of onboard systems, technical trials, and maritime certifications.

Magellan Discoverer will join the fleet during the 2026-27 season, with air-cruise expeditions starting in December 2026. As the construction of the vessel progresses, updates on the progress will be provided. The next update is expected to be released in January 2026.
