A Dutch yard, an aluminium habit
Heesen has been shaping fast aluminium hulls in Oss since the late 1970s, and the 50m Aluminium FDHF distils four decades of that knowledge into a Series owners can order with confidence. The yard offers it as a semi-custom project, engineered in advance so the delivery clock runs short and the surprises stay few. Van Oossanen Naval Architects supply the Fast Displacement Hull Form beneath the waterline, a shape that carries the boat efficiently across a wide band of speeds. For an owner, that means a yacht already proven on paper before the first plate is cut.
The Series sits below 500 GT by design, which keeps the yacht within a friendlier regulatory band and a lighter operating footprint. She measures 49.8 metres with a beam of 9.1 metres and a shallow 2.15 metre draught, so shoreside anchorages and thin Bahamian water stay within reach. Compliance with IMO Tier III sits in the specification from the outset. The result is a boat that behaves like a private residence at anchor and a genuine passage-maker when the owner wants to move.
Omega lines above the water
The exterior is the work of Frank Laupman at Omega Architects, a studio that has drawn many of Heesen's most recognisable profiles. The 50m carries long horizontal glazing and a low, purposeful sheer that reads as contemporary without chasing fashion. Large windows in the hull and superstructure pull daylight deep into the accommodation. From the dock she looks quick, and the hull form means she is.
Deck space is generous for the length, with a sun-soaked foredeck seating area and a broad aft cockpit that steps down to the water. The flybridge gives the owner an outdoor helm position and room for a spa pool and shaded dining. Tenders and toys stow in a garage that keeps the swim platform clear for guests. Every outdoor zone was planned around how a family actually uses a yacht at anchor.
Fast enough to reposition on a whim, efficient enough not to think twice.
Fourteen ways to feel at home
Below, the interior is styled by Cristiano Gatto Design, whose work on this platform favoured light woods and a soft, residential palette. The layout accommodates 12 guests across six cabins. The owner's suite sits forward on the main deck with floor-to-ceiling windows that frame the sea from the bed. A full-beam VIP on the lower deck gives a second principal cabin that rivals many owners' quarters elsewhere.
The main saloon opens to the aft deck through wide glass, so the boundary between inside and out softens the moment the doors slide back. Materials were chosen for the way they wear over years of use, not for a single photo shoot. Ceiling heights feel generous for a boat under 500 GT. The atmosphere is calm and bright, the kind of space an owner settles into for years.
A hull that changed the maths
The Fast Displacement Hull Form is the engineering heart of the Series. It blends the seakeeping of a displacement hull with efficiency across low and high speeds, so the yacht is comfortable loafing at 10 knots and willing when pushed. Twin MTU 12V 2000 M61 engines deliver a top speed near 16.3 knots and a range of about 3,750 nautical miles at 12 knots. Those numbers put real cruising grounds within one hop.
For owners who prize quiet, Heesen offers an advanced hybrid propulsion package. In hybrid mode at 10 knots the boat draws roughly 45 litres of fuel an hour, and it can idle through an anchorage on electric drive with the generators asleep. The saving shows up as lower running costs and longer, calmer evenings on board. This was the platform that first proved the idea, and it remains one of the most convincing cases for hybrid at this size.
The owner it suits
The 50m Aluminium FDHF rewards the owner who wants a private, self-sufficient yacht without stepping into full 500 GT territory. It is fast enough to reposition on a whim and efficient enough to do so without a fuel bill that spoils the mood. A short build slot and a proven platform appeal to buyers who would rather cruise this season than wait three years. It is a first serious yacht for some and a considered downsize for others.
Owners drawn to hybrid running and low-emission credentials find a boat that delivers both without compromise to comfort. The Series has a track record on the water, with Home and Ela showing what the platform becomes in private hands. For a family that values light-filled interiors and easy access to the sea, the case is straightforward. Owners in this bracket buy the boat to cruise it hard.
Who it is for: The owner who wants a proven, sub-500 GT ocean yacht with an optional hybrid drive and a short build slot.
