The yacht features an interior and exterior design by Winch Design and the British design studio has given the yacht a sporty, low-profile exterior with a reverse bow and a mix of "Venetian red" and metallic grey accents that give her a unique look and contemporary feel. The interior, meanwhile, sees each deck follow different themes of water, earth and air.
Arcon Yachts has acted as project manager for Sparta, working on behalf of the owner who was captured by Heesen's 66-metre Project Avanti concept, which was first presented at the Monaco Yacht Show 2018.
Heesen said that little has changed since the initial sketches were presented except for modifications to the aft deck pool, which now stretches to 6.5 metres.
As well as embracing the different elements, the yacht also follows themes of togetherness and family living, with an open-plan layout that aims to accommodate this.
Sparta's interior layout revolves around a pair of owner's suites situated on the bridge deck with access to a dining and al fresco area, while there are a further four cabins on the main deck for a total of 12 guests, two staff members and 14 crew. With family living in mind, there is a moveable partition that separates the forward cabins to create a full-beam VIP or a large playroom for younger family members.
Another key theme of the yacht is wellness, and Sparta benefits from a 65-square-metre spa on the lower deck that is home to an elliptical whirlpool, steam room, sauna, gym and beauty area.
The 1,200GT yacht has a custom Winch-designed Tenderworks limo tender that echoes the lines of the mothership, which is stored behind the gullwing doors of the forward garage.
In terms of styling, the earth-themed main saloon features dining chairs upholstered in real palm leaf, and the coffee table is made from parts of stained oak with a leaf-shaped green marble top complete with leather finish. On the deck above, one of the master suites takes its cues from air and uses soft fabrics, mother-of-pearl inlays and patterned Tai Ping carpet. Developing the "elements" theme even further, the forward section is a centred space and features a constellation wall artwork.
Richard Kaye of Arcon Yachts said: "This is the fifth project we have built with Heesen, and the mutual trust that has grown up between us is particularly gratifying. We know our input is valued, and we hold the expertise of this Dutch shipyard and the unrivalled quality it delivers in the highest esteem."
Key numbers include top speeds of 16 knots and a range of 4,500 nautical miles at 12 knots.
Peter van der Zanden, Heesen's head of engineering, said: "At Heesen, we take pride in our ability to create complex custom yachts that are expertly engineered and built to meet the highest Dutch quality standards. Our team eagerly embraces the challenges posed by full-custom yachts. It's an opportunity for us to showcase the exceptional levels of excellence we can achieve. Sparta is a testament to our commitment to delivering the finest superyachts."
