90’ Doggersbank – Major Refit (2020–2024)
Atlantic Yacht Sales is proud to present Belle Isle Sea, a 2001 90-foot Doggersbank Expedition Yacht that stands in a class of her own.
To describe her as “refitted” would be an understatement—this yacht has been comprehensively rebuilt from the keel up, with every system, component, and finish either upgraded or replaced to an exacting commercial standard.
The result is a true expedition-class vessel that feels and performs like a new build, offering the reliability, capability, and comfort of a modern yacht while retaining the proven pedigree of the renowned Doggersbank design. Belle Isle Sea is, quite simply, an exceptional opportunity for a discerning yachtsman seeking a turn-key global cruiser.
Built to the renowned Doggersbank design by Kuipers Woudsend and designed and overseen by Vripack, Belle Isle Sea is a 90-foot expedition-style yacht that exemplifies the rugged capability of a true ocean passage maker combined with the refined finish of Dutch craftsmanship. Constructed to Lloyd’s standards at the time of her build, she reflects exceptional quality and engineering throughout. Purchased in 2020, she underwent an extensive, multi-year refit beginning that October, during which every major system—mechanical, electrical, structural, and interior—was meticulously upgraded or replaced to bring her to near-new condition.
The result is a fully modernized, turn-key yacht ready for world cruising with the reliability, comfort, and efficiency expected of a Northern European build. The following is a detailed summary of the refit work completed.
