Delivered by Admiral Yachts in 2021, ALTHEA (47.50M/155’10) is a standout in the Atos 47 series.
Built in aluminum to RINA classification and boasting a volume of 499GT, she combines long-range capability with exceptional onboard features. A major technical and aesthetic refit at Monaco Marine in 2024/2025 brought ALTHEA to turnkey condition, including updates to her machinery.
Inside, ALTHEA’s layout is designed for entertaining and relaxation. The main salon flows seamlessly to the aft deck, with a formal dining area and lounge. Floor-to-ceiling windows flood the interiors with natural light and framed panoramic sea views.
ALTHEA comfortably accommodates 11 guests in 5 well-appointed staterooms. The full-beam Owner’s Stateroom is located forward on the main deck with ensuite bathroom and dressing area. Four additional guest staterooms are located on the lower deck, each with ensuite. Crew quarters are forward and fully separate for enhanced privacy.
Her contemporary silhouette is complemented by expansive decks, followed by a large beach club with a swimming platform. The tender garage stores toys and gear discreetly, keeping deck areas open and uncluttered. A large aft platform offers direct access to the water, ideal for guests who enjoy water sports or lounging at anchor.
Maintained to exceptional standards and still under Caterpillar warranty through 2030, she represents one of the most compelling fully VAT-paid offerings in the 50M segment.
