There are yachts that are used, and there are yachts that are loved. The 47.5-metre motor yacht Althea, built by Admiral in 2020, belongs firmly in the latter category. Part of The Italian Sea Group’s Atos 47 series, her build quality, maintenance and intelligent layout set her apart as one of the most distinctive offerings on today’s brokerage market. She has only been owned privately since launch, never chartered, and has been maintained with the utmost care - even her water toys were always placed on special blankets to ensure not a mark touched her teak.
Having recently completed a major technical refit at Monaco Marine in 2025, Althea is presented in turnkey condition. Her machinery has been refreshed, her systems updated, and her RINA classification remains valid until 2030. Combined with twin Caterpillar engines still under warranty for the next five years and remarkably low engine hours just under 1,150, she offers a level of reassurance rarely found in a yacht of her class. As her broker, Bryan Somerset Mehut of Fraser, explains, she represents “one of the most compelling fully VAT-paid offerings in the 50-metre segment”.
Italian design inside and out
Both Althea’s exterior and interior were designed by Gian Marco Campanino, whose vision delivers a contemporary silhouette defined by straight lines and a striking sky-blue hull. Built entirely in aluminium, her 499GT volume feels expansive and open, while her tri-deck configuration gives her guests multiple zones to relax, dine or entertain.
From the water, Althea’s presence is strong and assertive, but step inside and the effect softens, with natural light streaming through the floor-to-ceiling windows, and a décor of calm neutrals, pale woods and subtle textures. Minotti furniture and a flowing layout link the formal dining area and lounge, separated by a bar with a sliding television that disappears into the counter when not in use. It’s a space designed as much for family gatherings as for entertaining.
A family-first layout
Every element of Althea’s interior design has been considered for both comfort and safety, particularly with families in mind. There are no sharp edges anywhere on board, and one guest cabin even features a miniature cut-out door within the main bathroom door, designed to ensure a child could exit safely in case they became trapped inside. It’s these unique touches that distinguish Althea from her peers.
Accommodation is provided for 11 guests across five cabins. The owner’s stateroom stretches across the full 8.8-metre beam of the main deck, complete with a marble-clad en suite and a walk-in wardrobe. On the lower deck, a second owner’s cabin sits to starboard, opposite a VIP to port, with two additional guest cabins aft, one featuring a Pullman berth. Each guest cabin can be configured as a double or twin.
Living spaces for life at sea
Her full-beam skylounge on the upper deck, which recently benefitted from updated upholstery, doubles as a cinema lounge - a favourite retreat for movie nights or relaxed evenings at anchor. Aft of this, an inviting al fresco dining area offers open views across the water, ideal for candlelit dinners or shaded lunches on passage. Above, the 100-square-metre sundeck provides yet another realm of possibility, with vast sunpads and a retractable television for open-air cinema screenings. The owner could easily install a Jacuzzi up here, thanks to pre-installed piping. It’s an exceptionally versatile space, equally suited to quiet mornings under the sun or lively evenings with friends.
At sea level, Althea’s beach club transforms time at anchor into something special. Her swim platform is so large that it can accommodate sun beds or even a private dining setup just inches from the water with a Bimini overhead. Steps descend into the sea for easy access, while the transom hides a beach store equipped with all the essentials for waterside living, including a dayhead. From here, guests can swim, sunbathe or simply sit with their toes in the water, feeling connected to the ocean.
Functionality from bow to stern
Althea’s tenders and toys are stored on the foredeck, keeping guest areas completely uncluttered. She comes equipped with a brand-new Highfield 560 tender powered by a Yamaha 100hp engine and two Sea-Doo Jet Skis, and there is space for a 7.5-metre Castoldi tender if necessary. The crane here is discreetly hidden behind her bulwarks, preserving the yacht’s clean exterior lines.
For the crew, Althea’s spaces are generous. She accommodates up to 10 crew, including a captain’s cabin on the bridge deck. Separate galleys for guests and crew, dedicated entrances and passageways, and divided laundry and tender facilities ensure that operations run seamlessly and discreetly. “Unlike many other modern yachts that only focus on the guest areas, Althea has very decent crew spaces, so it is very balanced,” notes Mehut. It’s a small detail that reflects her owner’s belief in the well-known “happy crew, happy guests” mantra.
Power and efficiency
Powered by twin Caterpillar engines, Althea can reach a maximum speed of 19 knots, with a range of 3,300 nautical miles at her cruising speed of 12 knots. At an economical nine knots, she consumes just 110 litres of fuel per hour with generators running, making her well-suited to both Mediterranean cruising and transoceanic passages. With a draught of 2.1 metres, she can explore shallower bays and anchorages, while her zero-speed stabilisers guarantee stability both underway and at anchor.
Asking €29,500,000, Althea is currently lying in Golfe Juan, France, and is offered for sale with Bryan Somerset Mehut of Fraser, with VAT paid in full. For those looking for a modern 50-metre-class yacht that’s ready to go, Althea more than lives up to her name. Get in touch with Fraser for more information or to arrange a viewing.
