The Heesen 4400 Aluminium is a 44.6-metre semi-displacement superyacht that represents the sweet spot of the Heesen range, combining serious ocean-going capability with the performance and agility of an all-aluminium hull. At 450 GT, she offers the volume and comfort expected of a yacht well above her length.
Powered by twin MTU 16V 4000 M90 engines, the 4400 reaches 25 knots and cruises at 22 knots. With 69,000 litres of fuel, she achieves a remarkable range of 3,200 nautical miles, making her equally capable of Mediterranean island-hopping and transatlantic crossings.
Exterior and interior design by Omega Architects creates a harmonious profile with clean, confident lines and sophisticated, light-filled interiors. Five staterooms accommodate ten guests, attended by a crew of seven. The 4400 platform has proven one of Heesen’s most popular, with numerous hulls delivered to discerning owners worldwide. She represents the best of Dutch shipbuilding: precision, performance, and understated excellence.

Twenty five knots is fast for a yacht carrying this much volume.
Twin MTU 16V 4000 M90 engines carry the 4400 to a top speed of 25 knots and a settled 22 knot cruise. Hers is a twin propeller, hard chine, semi-displacement hull, shaped to hold that pace without the fuel burn of a conventional planing yacht her size. Heesen handled the naval architecture in house, drawing on three decades of aluminium construction experience to keep weight down without compromising structural integrity. The payoff shows in her range: 3,200 nautical miles on 69,000 litres of fuel, enough for a genuine transatlantic crossing rather than a theoretical figure quoted for brochures. Fixed fin stabilisers keep her settled at anchor as well as underway, and a 2.6 metre draught still leaves plenty of anchorages within reach for a yacht of this size.
Omega Architects gave her a profile built around volume, not just length.
At 44.6 metres with a 9 metre beam, the 4400 carries noticeably more interior volume than her length alone would suggest, a Heesen trademark across the Aluminium Series. Multiple sunbathing and dining areas run from the foredeck to the upper deck, giving guests several distinct spaces to choose from through the day rather than one crowded main deck. A transom garage swallows a tender and watersports toys, with a track launching system that spares the need for a crane every time someone wants to use them. The result is an exterior that reads as purposeful rather than ornamental, clean lines drawn to serve how the yacht is actually used, season after season, rather than how she photographs at the dock.
Five staterooms for ten guests, arranged so the owner never has to share a deck with anyone else.
The full beam master suite sits forward on the main deck with its own private study, a layout that keeps the owner’s quarters separate from guest traffic. Below deck, two VIP cabins and two further double cabins complete the five stateroom count, each finished to Omega Architects’ specification with the same light, considered palette carried through from the saloon above. A versatile upper deck sky lounge can convert into an additional cabin when the guest list grows, adding flexibility that fixed layouts of this size rarely offer. A crew of seven is accommodated separately, keeping the working side of the yacht entirely apart from where guests live and sleep.
The deck plan reads as a sequence of rooms, rather than one continuous space.
A forty five square metre sundeck tops the yacht, large enough for sunbathing and open air dining without feeling exposed. Lower down, both the upper and main aft decks carry their own dining arrangements, while the foredeck offers quadruple sunpads for guests who want to be away from the activity aft. The skylounge and main saloon, both shaped by Omega Architects, give guests somewhere enclosed and air conditioned to retreat to without leaving the main living deck. Moving between these spaces never means passing through a crew corridor or a service area, which keeps the yacht feeling considerably larger than her length on paper.
More than a decade into production, the 4400 Aluminium Series remains one of Heesen’s most consistent sellers.
Classed by ABS to A1 Yachting Service standard and built to the Large Commercial Yacht Code, she meets the requirements for both private use and charter operation. Several hulls in the series have been delivered to owners around the world, a track record that speaks to how well the platform has aged rather than how aggressively it has been marketed. Heesen’s own naval architecture and engineering underpin every hull, and Omega Architects’ design work gives each one a consistent identity even as individual owners customise their interiors. For a buyer who wants proven aluminium engineering, genuine range, and a semi-custom build process rather than a one off design exercise, the 4400 offers a well tested answer in the 44 metre bracket.
