The World, Residences at Sea, the largest privately owned residential mega yacht on the planet and the only one of its kind currently in operation, has successfully completed its most ambitious dry-dock to date, ushering in a new era of environmentally responsible and elevated luxury living at sea.
The ambitious six-week, $30+ million transformation at Navantia Shipyard in Cádiz, Spain marked a milestone in the vessel's ongoing commitment to continuous innovation, culminating in over 200 completed projects involving nearly 1,500 personnel across vendors, Crew, and technical teams.
Among the most notable energy efficiency improvements: The World installed a High Voltage Shore Connection (HVSC) system and made company history with its first successful shore power connection in Valletta, Malta on 12 July 2025, an important step forward in its commitment to energy efficiency and environmental stewardship. This sustainability milestone enables the Ship to shut down its engines and plug into onshore electrical grids where available—significantly reducing emissions and noise pollution while in port and limit its environmental footprint. Built in partnership with global technology leader ABB, the HVSC system features more than 600 meters of high-capacity cable and was commissioned and tested ahead of schedule before the vessel visits ports where this has become mandatory.
Additional enhancements included a reimagined amenity pool deck, refreshed Spa & Wellness Center, upgraded putting green, new 10-seat Zodiac, and comprehensive maintenance throughout. All energy efficiency upgrades reflect The World's commitment to the environment which could lower emissions by up to 10%. With Residents back on board, our 2025 journey across the globe continues.
"From reducing our environmental impact through shore power to elevating Resident life through modernized amenities, this achievement belongs to our entire community," said Jessica Hoppe, President & CEO of The World. "Our Residents have once again shown that they are deeply invested in the Ship's future—and in the future of responsible global travel."
Additional sustainability enhancements include:
Enhancements to public and private spaces included:
As a result of these efforts and meticulous ongoing maintenance, The World continues to outperform industry standards. Earlier this year following completion of a comprehensive study and extensive evaluation, DNV, a globally respected authority in maritime safety and sustainability, assessed the vessel as having a fatigue age of 5.6 years—remarkably only a quarter of her chronological age—and presented the Ship with a rare Statement of Extended Life at Seatrade Cruise Global.

With its Residents now back on board, The World has resumed its global itinerary. As the only 100% residential mega yacht at sea, The World continues to redefine private yachting—blending ultra-luxury living with global exploration and a steadfast commitment to environmental stewardship.
