The dimensions of Project 817 are closely linked to the construction site in the south of the Netherlands: the maximum yacht length that can be built in the halls in Kaag is 94 metres. And the width of 14 metres is just under the maximum dimension for reaching the North Sea via waterways. Van Lent built "Lady S" in the same place. The big difference to the 93 metres: a hybrid drive that is all about efficiency. The 817 owner, who according to the shipyard "has chartered all the Feadships on the market in recent years", wants its 94-metre steel-aluminium format to have roughly the same environmental impact as its 32-metre shorter predecessor, also supplied by Feadship.
The diesel-electric Project 817 will travel at a cruising speed of twelve knots and a top speed of up to 20 knots. A large battery bank ensures optimum utilisation of the generators and a stable on-board power supply. Due to the large floor-to-ceiling window areas - the superstructure has no bulwarks at all - a lot of development work went into the ecologically efficient operation of the air conditioning system. The first engineer can also utilise heat recovery.
Project 817 dispenses with a fixed bathing platform, but features four hull hatches - the one on the large tender is the longest that Feadship has ever integrated. The exterior was designed by Studio De Voogt, which belongs to Feadship, and the Dutch studio Azure. The interior features room designs by Peter Marino. The New York architect, who always appears in public in a leather suit, has already designed the first 100-metre Feadship "Symphony" and "T.M. Blue One" by fashion designer Valentino Garavani.
