A rare opportunity to secure a 181' (55.2m) Italian-designed superyacht now under construction, Hull 4 of the Admiral S-Force 55 offers one of the fastest delivery windows in her class, with completion scheduled for May 2027—just 20 months from contract. With her hull and superstructure already joined and viewable at the shipyard in Massa Carrara, she combines a proven platform with exceptional custom potential, offering high performance, bold aesthetics, and Italian refinement in a single, streamlined package.
Built by the acclaimed Admiral shipyard and styled by The Italian Sea Group, this 499GT aluminum yacht offers exhilarating capabilities with her semi-displacement hull, 2 x Caterpillar 1901 HP engines, and cruising speeds of 16.5 knots with a top speed of 18 knots. Her engineering supports a range of 3,500 nautical miles at 10 knots, making her equally suited for high-speed island hopping or long-range passages. Several options are selected, including standards aligned with commercial compliance, opening the door for private or charter-focused operation.
Inside, the S-FORCE 55 presents a light-infused sanctuary shaped by expansive floor-to-ceiling windows and a deliberate embrace of the sea. The in-house design team has proposed two customizable interior options, both showcasing rare and precious materials and an emphasis on clean volume and flow. A main deck salon opens aft to a convertible dining area for 10 guests, effortlessly transitioning from indoor formality to open-air elegance via sliding glass doors. An upper salon, notably asymmetrical to increase usable space, anchors a full beam entertaining area complete with a bar, and alfresco dining for 12.
Accommodation is generous and refined. The owner’s suite and private office occupy the forward main deck, enjoying expansive views and privacy. Below, the guest quarters include a VIP cabin and four additional guest staterooms, allowing for 12 guests across six cabins, all serviced by a crew of 11. Natural light, neutral tones, and refined textures continue throughout the accommodation spaces, enhancing the yacht’s home-away-from-home appeal.
Outdoor living is equally dynamic. Her sleek profile masks an array of standout amenities: two aft decks designed for lounging and alfresco dining, a sundeck Jacuzzi paired with a gym, massage bed, bar, and even a dedicated dance floor. Aft, a beach club with shaded sunpads provides a spectacular platform for ocean access via a custom swim ladder. Perhaps most unique is her touch-and-go helipad, a circular foredeck space that transforms from an arrival zone to an open-air cinema, sunpad lounge, or winter-ready firelit terrace. It's a true stage for all-season adventure.
This is the fourth unit of the successful S-Force 55 line, with sistership GECO already a top performer on the global charter market. With her performance pedigree, elegant styling, and fast-track delivery, hull 4 presents a standout opportunity for an owner seeking scale, speed, and flexibility without the wait.
