SAILING YACHT A – World’s Biggest Sailing Yacht – $600 Million

SAILING YACHT A measures 143 meters making her the world’s biggest sailing yacht.

SAILING YACHT A is far more than a luxury vessel. She is a masterpiece of design and innovation combining sleek metal surfaces with futuristic naval architecture that took over two years to complete.

Launched in 2017, both the interior and exterior of this mega sailing yacht were designed by Phillippe Starck, who calls SAILING YACHT A one of his most high-profile projects.

The superyacht has taken on voyages all around the world and was most recently spotted sailing off the coasts of Gibraltar and Cyprus.

SAILING YACHT A interior

Both the interior and exterior of SAILING YACHT A were designed by Philippe Starck , a French architect known for his wide range of design projects.

He famously worked on the impressive MOTOR YACHT A, and the two iconic vessels share a lot of similarities in their layout and specifications.

Both yachts look incredibly futuristic and are sure to attract attention wherever they go.

While no exact details are known about the interior of SAILING YACHT A, it is rumored that she has an underwater observation pod with 30 cm (1 ft) thick glass located in the keel of the vessel.

This is one of the few parts where design mockups are publicly available, and the style of the interior can be examined.

The observation pod appears to have cream upholstery that stretches across the floor and ceiling of the cabin.

Two large symmetrical glass windows allow guests to view the breathtaking underwater world without even having to leave the yacht.

A third window is located at the bottom of the pod, which lets it feel like a true 360-degree experience and is almost comparable to a submarine.

A small floating side table provides guests with a space to place drinks or snacks in the pod and enjoy a one-of-a-kind dining experience in this unusual location.

Since the pod is located at the keel of the yacht, the large propellers are most likely visible from the windows suggesting it is most commonly used at anchor.

The superyacht has ten cabins that can accommodate 20 guests as well as a further 54 crew member.

Paparazzi photos and the work of yacht spotters provide a rare glimpse into the interior of SAILING YACHT A.

No official footage of cabins or salons has been released, although Starck’s past work suggests that the yacht would be furnished with opulent elements that perfectly combine luxury with style.

Silver and metal decorations play a large role and tie the interior design of the yacht together. 

However, SAILING YACHT A was launched much later than her motorized companion suggesting her interior might be more modern with minimalistic elements rather than lavish furnishings.

Occasional photographs shot through open doors, and portholes show expensive art pieces decorating the interior of the yacht and rather absurd design choices like a set of chairs shaped like large human heads.

The yacht appears to feature a large, open salon with an elevated seating area and symmetrical arches on either side.

While details aren’t known to the public, it is rumored that SAILING YACHT A features a luxurious spa area, a sizable gym as well as an owner’s suite with several rooms that is only accessible via fingerprint.

The massive private area is said to feature a 60-inch television that disappears into the floor as well as a rotating bed. 

Considering she is the largest sailing yacht in the world, it is surprising that SAILING YACHT A can only host 20 guests.

This suggests that there are spacious entertainment areas located on board, including several saloons and ample below-deck space for crew members.

Due to her large size and a small number of cabins, it is assumed that SAILING YACHT A can welcome a large number of day guests onboard for special events and celebrations.

Biggest sailing yacht controversy

It has been the topic of debate that SAILING YACHT A is not the largest yacht in the world but instead the ‘largest sail-assisted motor yacht.

Depending on the definition used, that would make BLACK PEARL the biggest sailing yacht in the world.

The most expensive sailing yacht

SAILING YACHT A is the most expensive sailing yacht in the world and cost an estimated price of US $600 million – a relatively “affordable” price considering her large size and tonnage.

A calculated US $48,000 per ton is considered low in the yachting industry, where European yachts are usually priced at US $60,000 per ton and over.

This average price would bring the value of SAILING YACHT A up to nearly US $800 million. However, due to the fact that the official sales price has not been released to the public, these numbers are mere estimates and cannot be validated officially.

Since the yacht is a custom project and one of a kind, it can be assumed that the total value of SAILING YACHT A lies far higher than her initial price.

In addition to any cost for the crew, supplies, and docking fees, she has annual running costs of US $50-75 million.

SAILING YACHT A is currently not available for sale or charter.

Specifications

SAILING YACHT A is incredibly large for a sailing yacht, and even compared to the longest motor yachts in the world, she would rank in the top ten.

Paired with her unusual futuristic design, this mega sailing yacht has a length of 143 meters (469 ft), a beam of 25 meters (82 ft), and a draft of 8 meters (26 ft) making her a more than an impressive vessel.

SAILING YACHT A was built by Nobiskrug , a German superyacht builder at their Kiel shipyard, and launched in 2017 after more than two years of construction.

To date, SAILING YACHT A is the largest yacht ever built by Nobiskrug and remains their flagship.

It is considered the most complicated project to ever be completed in the sailing industry and gained international media attention on its launch date. It has a total volume of 12.558 tons and is powered by hybrid diesel-electric engines. 

SAILING YACHT A is considered the longest sailing yacht in the world and is more than 36 meters (118 ft) longer than BLACK PEARL, which ranks in second place on the list.

Coincidentally her project name was WHITE PEARL which is a reference to her brilliant white exterior, although it couldn’t have referred to BLACK PEARL since she was only launched in 2018, a year after Melnichenko’s masterpiece.  

Her three-carbon masts stand at an impressive 100 meters (328 ft), making them some of the largest in the world and taller than Big Ben in London.

However, her large size is sometimes also limiting as she struggles to fit underneath most bridges and is therefore constrained to certain routes.

She once passed under the Golden Gate Bridge in San Francisco with only 20 feet to spare between her masts and the bottom of the famous bridge.

She is rumored to have an electric gimbal crow’s nest, which allows for remote operation and advanced wind measurements. Her sails are all white, and her masts have nearly sickle-like shapes, which add to her striking futuristic appearance.

It is noteworthy that she is commonly photographed with her sails down, which suggests she might be using her support engines more frequently than true wind power.

With a sail area of more than 3.700m^2 (40.000 square ft), she can reach top speeds of up to 21 knots which is supported by her twin 4895 Horsepower MTU engines .

Her average cruise speed lies at 16 knots, and her total range is estimated to lie at 5320 nautical miles. She features a state-of-the-art sail system that is able to raise and lower the sails and anchors at the touch of a button. 

SAILING YACHT A has a steel hull and composite steel superstructure, which is unusual in the superyacht industry as most shipyards choose aluminum to reduce weight and keep the vessel light.

She currently sails under the flag of Bermuda, which is common for prominent sailing yachts.

During construction, SAILING YACHT A was called project WHITE PEARL, a fitting name for this sizable vessel.

Like her interior, the exterior of SAILING YACHT A was designed by Philippe Starck, although the Dutch studio Dykstra Naval Architects played a role in the naval architecture of the vessel.

They specialize in sailing yachts of all sizes and have been involved in many prominent projects in the industry over the years.

She features eight teak decks with a large swimming pool located in the center and several elevators spread across the yacht.

She is even said to carry a submarine. The main pool is lowered into the deck allowing for additional privacy for the owners.

Her hull has 24 shell doors, which are used to access equipment and provide additional deck space if needed. She is accompanied by four tenders also designed by Philippe Starck and built by Lloyd Stevenson in New Zealand.

Their sleek and elegant design matches that of the main vessel, and they are used for transporting guests and taking them on excursions.

One of the tenders of SAILING YACHT A is a carbon fiber speedboat especially reserved for the owner who can operate the vessel autonomously whenever required without the aid of crew members.

This allows Melnichenko, who is a fan of driving high-speed cars to be independent when staying aboard his luxury yacht. The tender is small but powerful, reaching speeds of up to 53 knots.

The larger tenders can seat up to eight passengers and feature panoramic windows ideal for sightseeing and exploring but are much slower at only 30 knots. 

The aft features a large garage used for storing jet skis, tenders, and other equipment.

High-profile artists such as Snoop Dogg are rumored to have performed here, although detailed evidence of such concerts remains unknown.

Whenever the aft isn’t used for performances or parties, it can be transformed into a swimming platform designed in the yacht’s iconic futuristic style. 

However, despite her cutting-edge design features, SAILING YACHT A surprisingly also includes classic nautical elements. She has a wooden steering wheel that is reminiscent of a pirate ship, although it is not operational.

The captain of the vessel can instead use modern technologies to operate the massive yacht via a small joystick and touchscreen.

There are symmetric extendable balconies that protrude from the bridge of the yacht and allow the crew to have a better view to be able to gauge the dimensions of the immense vessel.

Of course, SAILING YACHT A has a modern underwater lighting system that illuminates the vessel perfectly at night.

Six facts about the build of Sailing Yacht A

One of the largest superyachts in the world , the 142.81 metre Sailing Yacht A has pushed the boundaries of yacht building. We reveal some of the most amazing facts about how this boat came to be.

The construction of Sailing Yacht A

This incredible superyacht was commissioned by Andrey Melnichenko. As owner of Motor Yacht A , we knew Sailing Yacht A would be anything but conventional. Melnichenko is one owner who delights in challenging the status quo and moving the game on, introducing new techniques and technologies in his yacht projects. Sailing Yacht A ticks both boxes: at 142.81 metres LOA, the “sail-assisted motor yacht” is one of the largest superyachts in the world.

Working once again with Philippe Starck on the design, Melnichenko assembled his own team to take the project from concept to completion. He chose Dirk Kloosterman, a veteran project manager of superyacht builds, to lead it. Kloosterman was involved in the build of Larry Ellison’s Rising Sun before taking on Motor Yacht A for Melnichenko.

Sailing Yacht A  is his biggest undertaking. Kloosterman’s first challenge was to find a shipyard with the capabilities to build such a vessel. Few major deep-water shipyards wanted to take on the risk of such a radical project, but Nobiskrug’s purchase of part of the HDW yard in Kiel, Germany, presented an opportunity.

“This was an excellent facility, with its large docks and the draught needed for the project,” Kloosterman says. “In March 2011, we signed the deal for pre-engineering to start. It was made clear to the yard that the team wanted large input and control over the build so the standard tender-and-bid process, with the yard supplying subcontractors, was scrapped. Cost control for an eight-deck motor yacht, with the added dimension of sailing, was going to prove challenging.”

Sailing Yacht A's imposing scale

Sailing Yacht A is a sharp, three-masted motor yacht with sailing potential, constructed mostly in steel incorporating composite and carbon fibre to keep weight down. In profile from her high bow, the sheerline climbs aft, before dropping down to an almost retroussé stern. The line is seamless, without interruption or sight of any deck equipment, anchors, balconies or openings of any kind, but they are all there, cleverly hidden away. Astonishingly, there are 24 shell doors in the hull.

The windows, which are all oval, look small from a distance, but all have a magnifying effect, making them seem huge from the inside. A special one-way film covers the exterior of the glass for privacy and helps to blend them into the custom metallic paint finish by Alexseal.

Her scale is extraordinary: 142.81 metres LOA, with a maximum beam of 24.88 metres and a draught of eight metres. She has eight decks, connected by multiple elevators and free-floating spiral staircases, garages for four tenders and a submarine, as well as a touch-and-go helipad on the bow. Every part of her interior has been designed to be flowing and organic.

Inside, up to 54 crew will run a professional galley large enough to serve a hotel and a powerplant and hotel services, stretching uninterrupted across two decks. In contrast to the volume of the everyday living accommodation is arguably the most incredible feature on board, occupying the smallest space: an underwater viewing pod moulded into the keel, offering a view of the props.

To make sure it all worked, hydrodynamic research facility HSVA in Hamburg performed towing tests for the hull, and the Wolfson Unit at the University of Southampton carried out wind tunnel tests to determine aerodynamic loads. This phase of the project revealed the optimal combination of sailing characteristics, seakeeping behaviour and performance under power. MARIN, in the Netherlands, conducted final tests of the model with keel and rudders.

With simulated aerodynamic loads applied, results concluded that the yacht’s heeling angle when under full sail would be a maximum of 12 degrees at 20 knots true wind-speed upwind and 35 knots downwind.

The rig and sail plan of Sailing Yacht A

Three colossal unstayed masts – the largest carbon masts in the world – define Sailing Yacht A . The mainmast towers 100 metres above the waterline – taller than Big Ben. An enclosed electric gimballed crow’s nest is incorporated, to whoosh a crew member 60 metres up the mast for what will surely be one of the most amazing views on the water. Dykstra Naval Architects , the Dutch naval architect that designed the rig for Maltese Falcon , was the obvious choice to develop an easy-to-use and safe sailing system.

Being “sail assisted”, the ratio between sail area and the yacht’s displacement is somewhat lower than would be found on a pure sailing yacht. Dykstra optimised the sailplan with full roach sails and freestanding aerodynamically efficient masts that can be rotated a total of 70 degrees to increase lift-drag characteristics.

Curiously, the masts are curved. “When we started to design this rig,” explains Mark Leslie-Miller from Dykstra, “the distinct feature of the freeboard sloping up towards the stern was already defined. For styling reasons, we wanted the foot of the sails [thus the booms] to align with the sheerline.” Sails this big would need to furl rather than flake when not in use. Furling booms, however, have to be at 90 degrees to the mast in order to work. Rather than tip the entire mast forward to preserve the right angle, Dykstra designed in the curve to keep the design aligned.

Magma Structures in Portsmouth, UK, developed the unique freestanding spars in carbon fibre, the only material that could cope with the stresses involved; masts this size cannot, in fact, be built using metals, according to Magma’s Damon Roberts, and they posed quite a challenge for the team. “Since the rig concept is unprecedented on this scale, there were no easy answers or standard solutions for any of the challenges that the rig design posed,” he says.

The sail and booms on Sailing Yacht A

With the masts designed to carry the whole load, they were able to calculate the maximum bending-force load on the lower bearing by using the predicted upper wind speed limit. “Allowable material stresses and safety factors then clearly led to the structural requirements for the design,” Roberts adds. The bending load at deck on the main mast, for instance, is about two-and-a-half times that of a Dreamliner aircraft wing and about two times that on Maltese Falcon , which has the highest-loaded freestanding masts to date. To put it another way, the masts can withstand 90 knots of wind with full sail up (equivalent to a Category 2 hurricane), or two double-decker buses hung from the tip of each.

Magma built the masts using high-strength carbon/epoxy prepreg laminate. Each mast was produced in four large sections: top and bottom, port and starboard. In the lower sections, 370 layers of carbon were laid up in open moulds. For the curing, Magma designed and manufactured oven software to monitor and control the cook cycle over a three-day period. Embedded in the masts is a network of fibre-optic sensors to give real-time comprehensive load data for safety, historical data, condition monitoring and sail performance optimisation.

The total sail area of 3,747 square metres is equal to the size of half a football pitch, and is 67 per cent larger than Maltese Falcon’s 2,370 square metres. Unlike the many small sails that deploy from Falcon’s mainmast, Sailing Yacht A’s fully battened mainsail, at 1,464 square metres, is a single piece and furls on a carbon-fibre mandrel inside a U-shaped boom at the press of a button; no crew are required. The total length of fibre used in the sail is 754 miles, or long enough if pulled straight, to stretch from the shipyard in Kiel to Monaco.

The sails, by Doyle Sailmakers of the US, are a combination of carbon and Technora fibres and covered with taffeta to protect them from UV. The trick was determining compression loads on the battens and then engineering a soft inboard end capable of furling reliably but, at the same time, handling the forward thrust of the battens without tearing. Future Fibres, in Valencia, constructed the carbon-fibre booms, which measure 25 metres (foresail), 27.5 metres (mainsail) and 23.6 metres (mizzen).

Glass technology on Sailing Yacht A

Germany’s GL Yachtverglasung (GLY) developed the yacht’s glass, including the longest piece of curved glass ever made: a 1.8-tonne, 15 metre bulwark forward on the bridge deck. “The designer wanted to make the look as clean as possible and preferably without railings. The only way to make invisible railings was to make them out of glass,” explains Kloosterman.

Two other huge glass bulwarks are found on deck seven, at 11 metres in length, and forward of the owner’s deck, at 14 metres long. GLY also supplied three elliptical-shaped pieces for the underwater observation pod that is moulded into the keel. By using special GLY-MarineCobond interlayers during lamination, the company reduced the glass thickness and weight by as much as 50 per cent compared to typical windows.

Meeting Lloyd’s requirements that the underwater windows had to be tested at 10 times the working pressure took a bit of ingenuity. GLY built a steel tank and bolted on the observation pod windows then moved this assembly to Bodensee on the southern border of Germany and sunk it to the bottom of a 120 metre-deep hole to create the adequate pressures. The nearly foot-thick windows passed the test.

Sailing Yacht A's propulsion

One of the most important design factors was keeping the weight down as much as possible, so the choice of propulsion was key. The goal was to achieve a cruising speed of 16 knots and a 21-knot top speed and be able to sail silently. The solution was unlike any ever installed on a yacht: a customised diesel-electric system. Building on a basic concept from river cruisers, EMS in Hamburg developed this system and then MTU, together with Vacon and DEIF, took it further.

“We use variable-speed generators,” explains Kloosterman. “This means that we can get more power out of a generator because we can run up to 2,050rpm (giving 2,800kW) and the advantage is that instead of requiring five generators we only need four. This means a large saving in weight but also in costs of purchase, installation, operation and maintenance.

The generators can also spin down to 1,050rpm when load is less; the Superimposed System Controller (SSC) constantly calculates the optimal speed and determines the best combination of generators on line. For example, the SSC may ascertain that at a particular electrical load it is more fuel efficient to run two generators at 1,200rpm than run one generator at 2,050rpm. Running two at a lower speed can have many advantages such as reduced noise/vibration, reduced overall fuel consumption and reduced engine wear.” Maintenance intervals will almost certainly increase, says Kloosterman, from 15,000 hours to as much as 30,000 hours.

The pair of propellers can be driven by the twin MTU 20V 4000 ML73 main diesel engines or by electric motors or by a combination of both through clutches and gearboxes. The same electric motors can also be used as economical shaft generators when the main engines are driving the yacht.

“There are a variety of separate propulsion modes to suit the requirements of cruising and sailing; the propulsion system is very flexible, and I believe this is the future of yacht propulsion,” Kloosterman says.
