At 200m, Double Century is the largest motoryacht concept to come from Australian designer Christopher Seymour. With eight elevators, two helipads, and a theatre that can seat 126 guests, there is plenty to keep guests entertained.

Working together with Florida-based brokers 4Yacht in marketing the project, Seymour set out to create a design that would be an evolution of the gigayacht. Achieving a sleek design that doesn’t result in an aesthetic more in line with a cruise ship is not an easy task. Nevertheless, Seymour has managed to create a sleek exterior despite having nine decks and stretching 27m above the waterline.

“I find the bigger the canvas, the easier the lines become,” says Seymour. “However, making 200m work on water ergonomically and keeping it practical was a challenge. I’ve tried to keep the stern areas for entertainment purposes and the forward sections can be utilised for the main tender/helicopter/cars/submarine storage.”

Accommodation for 50-plus guests is provided across the upper decks with the owner’s suite and VIP cabins situated forward on the seventh deck. Aft of the owner’s master cabin are suites for family and guests, with a small cinema, study and office also located close by. Lounge and entertainment areas complete with open bars, dining and a piano are also located on this deck. Additional guest accommodation is located on the deck below, including a second owner or VIP suite forward, allowing multiple owners to utilise the vessel at the same time. The sixth deck also features a dining and large lounge area for the owner complete with a piano and three open bars.

The foredeck is home to two helipads and a hangar bay for the storage of an EC135, allowing guests to come and go without impacting on the owner’s travel plans. Connected to these platforms is a waiting lounge with storage for tenders and toys such as cars and submarines located on the deck below. This frees the aft decks for the inclusion of pools, spas, bars, sun beds and lounging areas.

Stairways aft of each deck connect the main deck to the sundeck, which are protected from the elements thanks to specially developed pillars. “Angled cyan pillars cover the staircases, which were originally designed to increase efficiency when underway by deflecting wind after it wraps around the cabins,” says Seymour when asked which of the many features on board was his favourite.

Other features of the interior is the inclusion of a theater/stage which can seat up to 126 guests, a disco with a large dance floor, bar and a turntable area. In addition to the two large swimming pools aft of the main and lower decks are quarter moon lounges, several beauty and massage spaces, open gyms with saunas, a library with a garden, New York- and Monte Carlo-style cafes, a cinema, and a large beach club. Double Century will also offer a bespoke GPS phone app to provide guests and crew with information about their location.

Using a single gas turbine generator producing 19,000kW coupled with twin diesel 16V32/40 generators producing 7,500kW each, a top speed in excess of 20 knots and range of 9,000nm at a cruising speed of 15 knots is expected. A large tank system that pumps water around Double Century together with six Quantum Maglift ML600 stabilizers will ensure comfortable when at sea.

The project, which is still under development, has been priced at an estimated 699 million euros. While the client will ultimately decide on the interior design studio for the project, the team is exploring possible partnerships to give prospective clients an idea of what the finished gigayacht could look like. If built, Double Century would be 20m longer than the current record holder for the longest privately owned superyacht, Azzam.

“What Double Century needs is someone with vision, someone who wants to give life to an exceptional vessel, make it their own and put a distinctive stamp on the luxury yachting industry,” commented Craig Timm at 4Yacht.
