Double Haven: A Superyacht Ahead of Its Time
December 11, 2025
When Feadship signed the LOI for Double Haven in 1991, the yard announced they were about to build “the most sophisticated, complicated and unique superyacht ever constructed.” Decades later, her original specifications still stand strong alongside today’s most advanced vessels — a rare example of engineering and design vision that truly transcended its era.
Double Haven was conceived as a fully bespoke project: a private owner’s deck, flawless separation of guest and crew circulation, and spaces designed for multifunctional, intuitive use. Materials, construction quality and detailing represent what is now considered the highest modern standard, while ultra-low noise and vibration levels create an exceptionally calm and refined onboard atmosphere.
Double Happiness — the heart of the concept
At the center of the design is the purpose-built tender Double Happiness — a 7.8-meter jet-drive catamaran around which the entire mothership was envisioned. Created for serious fishing and diving, it reaches 25 knots, offers a 200-mile range, has a shallow 55 cm draft, standing headroom, a galley and a fully enclosed forward cabin. Its smart lowering transom becomes an ideal dive and boarding platform, with configurable seating for different activities.
Once Double Happiness is launched, Double Haven’s stern opens into what today would undoubtedly be described as a full beach club — spacious, elegant and perfectly connected to the water. Together they form a rare mothership-and-tender ecosystem that enables extended exploration, privacy and effortless comfort.
Public appearance
Double Haven will be showcased at the Palm Beach Boat Show in March 2026. A beautifully published book detailing her innovative design and construction is also available.
