ALTHEA (formerly known as CROCUS) sets a new standard in maritime excellence with its exceptional features. Crafted by Admiral Yachts, ALTHEA is a sleek vessel based on the ATOS model and seamlessly combines the essential technical features expected by seasoned yachtsmen on a 155-foot craft, with numerous tasteful Owner enhancements

This beautiful Admiral Yacht perfectly balances luxury and minimalism. ALTHEA’s harmonious palette of earthy tones, large glass windows, and expansive outdoor areas come together to create the most serene cruising experience. 

A dedicated team employed by the Owner oversaw the construction, ensuring meticulous adherence to design plans and top-tier quality. Safety took precedence, from furnishings and equipment to outdoor finishings, the well-being of all on board, especially children, was taken into account without compromising luxury. A dual-galley system caters to both crew and guests, exemplifying thoughtful design. An advanced ventilation system ensures a fresh purified experience inside, while separate areas and passageways provide privacy for crew and guests. The expansive beach platform offers unparalleled access to the water, complemented by floor-to-ceiling windows that flood the interior with natural light, creating an immersive connection to the surrounding environment. ALTHEA embodies luxury, safety, and unparalleled comfort in every detail.

ALTHEA’s beautifully balanced proportions create a feeling of equilibrium that is second to none. The geometrical lines of the yacht’s sleek silhouette bring a cohesive feel to the main deck, sun deck, lower deck, and beach club, creating a clean, minimalist profile.

With her 155-foot/48m aluminum exterior, ALTHEA is a spacious super yacht. Enhancing the views from the vessel, the 1,076-square-foot/327m2 sun deck sits below two oversized sun pads, creating a sheltered dining area. The warm tones of the materials highlight the sea views and give the boat a luxurious finish. The exterior features teak handrails with contrasting Wenge wood strips, while the interior draws on Italian influences, keeping the overall feel light and balanced.

ALTHEA boasts high-quality performance and maximum efficiency, remaining under 500 GT. Her twin CAT C32 Acert engines allow the motor yacht to reach a cruise speed of 12 knots and a top speed of 19 knots.

ALTHEA has a Registro Italiano Navale classification and flies the Malta flag.
