What’s in-build: YN 18950 Project Aquamarine

LOA: 50m

Interior designer: Cristiano Gatto

Exterior designer: Omega Architects

Naval architect: Heesen

Builder: Heesen

How did the project come about?

“We introduced the 50m all-aluminium semi-displacement back in 2011 when we delivered the multi-award-winning Satori,” says the yard. “We built seven sisterships, all with unique interior designs. The most recent is Masa, was delivered last year. We decided to renew the project, so we started a whole new design.”


Consequently, this fast-cruising, all-aluminium motor yacht has a new hull design by Heesen’s in-house naval architects, who worked with hydrodynamicists Van Oossanen Naval Architects. They carried out computational fluid dynamics tests, optimised the hull shape, and tank tested a 1:16 scale model. The result was an efficiency gain of 12 per cent. This was achieved by raising the transom and making it sleeker, and by incorporating propeller tunnels into the hull. This means that the 5000 Aluminium class features raised propellers, which decreases the draft to 2.15 metres, allowing shallow cruising in areas such as the Bahamas. A pair of interceptors also ensure optimal dynamic trim at high speeds.

The yard installed MTU’s new 16V4000M65L green oceanic engines, which have been specially developed to operate with a Selective Catalytic Reduction unit to reduce NOx emissions. As a result, Aquamarine is the first fast-cruising yacht below 500GT to be IMO Tier III compliant. The installation of soot filters on the generators further enhances the boat’s green credentials.


What was the design brief?

Frank Laupman of Omega Architects was asked to create “an elegant 500GT 50m vessel that felt different from previous models,” says the yard. He created balanced superstructure, with arches that “visually glue” it to the hull, a feature that Laupman refers to as the “integrated hull and body design”. The styling features sharp, chiselled edges.

Designed to complement the crisp lines of Aquamarine’s exterior, the linear and paired back interior by Cristiano Gatto underlines a pervasive contemporary theme. Floor-to-ceiling glass and uninterrupted sight lines are intended to enhance a sense of freedom at sea. Bespoke furniture will feature throughout the yacht, alongside pieces by Italian manufacturers such as Flexform, Armani, Giorgetti and Bottega Veneta. For deck spaces, Gatto chose loose furniture by Tribu, while most tables and coffee tables are custom designed.


Name one standout feature on board?

The large tender garage-cum-beach club creates an attractive close-to-water experience. It also melds well aesthetically with the arches and integrated hull and body concept.”

What is the status of the build and when is the scheduled delivery date?

“Outfitting is in full swing”, says the yard. Inside the accommodation all piping and HVAC works have been completed and the luxury carpentry is currently being installed throughout the vessel. The final 25% of the equipment is being installed in the engine room while piping and electrical installation is ongoing.
