The Ilumen 28M is what happens when a builder refuses to treat a 27-metre yacht like a series product. Every hull leaves Dominator’s Italian yard as a one-off, shaped around its owner rather than a brochure. What sets her apart is light and volume. Floor-to-ceiling glass wraps the main deck, and a retractable ceiling above the master suite slides open to reveal a private bow terrace with 270-degree views, a feature almost unheard of at this length. Alberto Mancini drew the exterior; Andrea Agrusta engineered the semi-displacement hull beneath it, and the pairing won a Boat International Design and Innovation Award for naval architecture. Construction is glass and carbon composite with postcured epoxy and a megayacht paint system, certified to ISO CE Category A and available to MCA MGN280. Interiors run to backlit white onyx, ebony and zebrano, brushed steel and hand-stitched nubuck, closer in feel to a contemporary villa than a production interior. Four to five cabins sleep the owner’s party, with berths for up to four crew. Twin MAN, MTU or CAT engines give a 21-knot top end and a relaxed 13-knot cruise, while a hybrid version stretches range toward 3,000 nautical miles. For a buyer who wants genuine authorship over a compact superyacht, and the volume of something longer, the Ilumen 28M is a rare proposition.

Twin engines, up to MAN or MTU V12s at 1,800 horsepower, drive the Ilumen 28M to a top speed of around 21 knots. The more telling number is efficiency. Her semi-displacement hull, the product of Agrusta’s hydrodynamic research, settles into a 13-knot economic cruise that returns roughly 1,000 nautical miles of range, and the hybrid variant pushes that toward 3,000 miles at 10 knots. Fuel capacity runs to 9,000 litres, with long-range tankage adding several thousand more. Draft is a shallow 1.32 metres with propellers retracted, opening up anchorages that deeper hulls cannot reach. This is not a yacht built to chase outright speed. It is built to move a heavy, glass-walled superyacht volume efficiently and quietly, and the electric powertrain option signals where Dominator expects owners to spend their time: cruising, not planing.
Mancini’s exterior is defined by glass. The Ilumen 28M carries more window area than almost anything of her length, and the effect is deliberate: the boundary between inside and outside nearly disappears. The signature move is the master suite’s retractable ceiling, which opens to a private bow terrace and turns the forward deck into an owner’s sanctuary rather than ground for the crew. Double sliding glass doors connect the suite to that terrace. Elsewhere the profile is clean and low, with unbroken lines that keep the 27-metre hull looking longer and more contemporary than her measured length suggests. Deck spaces are arranged for privacy first, with the social areas aft and the owner’s world forward. It is a design that treats the exterior as living space, not just passage, and does so without resorting to gimmicks.
Inside, the Ilumen 28M reads like a villa that happens to float. Backlit white onyx, ebony and zebrano wood, brushed steel and soft nubuck leather set a tone of restraint rather than display. Floor-to-ceiling windows flood the main deck with daylight, and ceiling heights feel generous for the length. The layout runs to four or five cabins depending on the owner’s brief, with the full-beam master benefiting from the retractable ceiling and bow terrace. Because every hull is bespoke, no two interiors are identical: materials, joinery and cabin count are decided with the owner rather than handed down. Crew quarters accommodate up to four, keeping service discreet. This is accommodation designed to be lived in over long stays, not merely admired at the dock.
The Ilumen 28M concentrates its social life where the views are best. The main-deck saloon, wrapped in glass, flows aft to the cockpit and forward, through the master, to the bow terrace, so the whole upper volume works as one connected space. Sliding partitions let the owner open or close zones as the day demands. The bow terrace is the party trick: a private, sky-open lounge at the front of the yacht, a rarity on a hull this size. Combined with the beach-level access aft, the yacht offers two distinct entertaining environments, one intimate and elevated, one social and close to the water. For a compact superyacht, the range of usable outdoor living is unusually broad.
Built in Italy to ISO CE Category A, with MCA MGN280 compliance available, the Ilumen 28M is engineered for serious use rather than coastal show. Construction in glass and carbon composite with postcured epoxy keeps weight down and stiffness high, and the megayacht paint system gives a finish to match yachts well above her price. Twin 36-kilowatt generators and the option of a hybrid electric powertrain point to an owner who values quiet nights at anchor. On the used market, hulls from 2017 and 2018 have traded between roughly 4.5 and 5.5 million euros, a reminder that these yachts hold interest well. For a new commission, the appeal is simpler: a genuinely bespoke superyacht experience, at a length that one owner can still comprehend and command.
