Built by Italian shipyard Admiral Yachts and delivered in 2020, Althea is a custom model and features interior and exterior design by Gian Marco Campanino Design, while Admiral developed her naval architecture. Constructed with an aluminium hull and superstructure, the 499GT superyacht was refitted in 2025.
The yacht for sale's interior embraces a contemporary residential feel, showcasing soft architectural lines with a restrained palette of pale oak, tropical ebony, statuario marble and Alcantara. Floor-to-ceiling glazing fills the main saloon with natural light, while the open-plan arrangement creates uninterrupted views through to the aft deck. The upper deck skylounge offers a more relaxed setting with curved seating and direct access outside, echoing the refined design approach found aboard the Admiral Yachts A-40.
Life on deck is centred around generous entertaining spaces spread across three levels. A 100-square-metre sundeck features an outdoor bar, integrated sunpads and open lounge areas framed by glass bulwarks, while the upper aft deck provides a sheltered dining space connected directly to the skylounge. At water level, the beach club, bathing platform and tender garage for craft up to seven metres enhance time spent at anchor, with the emphasis on versatile outdoor living continuing aboard larger yachts such as the Admiral Yachts Panorama 53.
Accommodation onboard the motor yacht for sale is provided for up to 10 guests across five cabins. The full-beam owner's suite occupies the main deck and incorporates a private lounge, study and panoramic windows, while the lower deck houses a VIP cabin, two double cabins and a twin cabin with an additional Pullman berth. Separate accommodation is available for up to 10 crew, including the captain.
Twin Caterpillar C-32 Acert diesel engines provide a top speed of 19 knots and a comfortable cruising speed of 12 knots. At an economical speed of 10 knots, Althea offers a range of up to 3,300 nautical miles, while underway and at-anchor stabilisers improve comfort in varying sea conditions. Buyers looking to compare larger Admiral superyachts may also wish to explore the Admiral S-Force 55.
