As mentioned inside the article of Boat International “10 of the biggest superyacht conversions“, PROJECT Y910 can be found in the list. this 120-meters superyacht is currently under construction and is ready for outfitting by her next future Owner. Lying in Fincantieri Trieste and with a realistic delivery of 18 months, PROJECT Y910 can become one of the largest superyachts in the world. Whether you dream of designing the ultimate expedition yacht, research vessel, one-of-a-kind floating residence, or an opulent charter experience, a team of architects, engineers, and designers are available to help you make that dream a reality.

As Boat International states, let’s see here below which are the 10 biggest superyacht conversions:

By meaning a conversion project refers to transforming a vessel that has been built with a specific purpose (research vessels, transport ships, ice-breaking tugs, etc) into an asset for beauty.

1. 141-meters YAS

Delivered in 1978 as a naval frigate for the Dutch Royal Navy and the UAE military, she was released from duty and converted into a private yacht under the codename Swift 141. Jacques Pierrejean is the author of her futuristic design which includes a giant glass dome. The entire project was carried out in Abu Dhabi and launched in 2011. Throughout the conversion, the vessel was extended by 12 metres to introduce a new pool deck.

2. 125-meters MARYAH

The 125 metre former Russian research vessel has been converted into a SOLAS-compliant superyacht by Greek shipyard Elefis in 2015. Details of her interiors are confidential, even though some information say to feature a cinema and accommodation for 54 guests across her six decks.

3. 121-meters ALEXANDER

Built in 1965 to serve as a cruise liner, ALEXANDER was then converted in 1985  into a superyacht by Greek shipping tycoon John Latsis. She was extensively refitted in 1985 and then again in 1998, with accommodation for up to 80 guests in 40 staterooms. Highlights include a swimming pool, hospital, gymnasium, a 27-seat cinema and a helicopter landing pad.

4. 120-meters PROJECT Y910

Built in Poland in 1990, the 90 metre vessel served as an offshore supply ship named after the Russian writer Vladimir Chivilikhin. With sustainable development at heart, this 120m luxury  project “recycles” an existing ice class hull, by lengthening it, adding a complete new aluminum superstructure and a hybrid diesel electric propulsion to deliver a brand-new concept. The hull and superstructure are all but finished, and what remains is the luxurious interior and deck amenities to your specifications, including the possibility of up to 18 staterooms and all common areas. PROJECT Y910 is currently lying in Fincantieri, Trieste, and ready for outfitting. She is exclusively for sale at auction in collaboration with Althaus Luxury Yachting and Concierge Auctions.

5. 116-meters TURAMA

Delivered in 1990 as a 116-meters passenger ship, TURAMA has been converted into a luxury charter yacht in 2004.

6. 106-meters DREAM

Under the project name Poseidonos, work began in 2008 at Chalkis Shipyards in Greece with exterior design by Studio Vafiadis. the result of this conversion project was known under the name of DREAM – rewarded in 2019 as the “best converted yacht” at the World Superyacht Awards.

7. 99-meters CHRISTINA O

Built for the Canadian Navy as an anti-submarine frigate, the vessel has gone through a long conversion project after having survived in the second world war. A six-year conversion ensued and she was reborn in 1954 as an ultra-luxury private yacht that was regularly seen to host royalty and the Hollywood A-list with the likes of Greta Garbo, Marilyn Monroe, Frank Sinatra, Sir Winston Churchill, Grace Kelly, John F Kennedy and Elizabeth Taylor welcomed on board.

8. 91-meters VOYAGER

Previously known as Danah Voyager, the conversion of this former offshore supply ship is the largest to take place on American soil. First delivered by Swiftships in 1997, the 63-meters commercial vessel emerged from the sheds three years later as a 90 meters explorer with five decks, 70 crew and a dive center.

9. 90-meters DUBAWI

Built in 1989 by Cantieri Navale Ferrari, DUBAWI was converted into a private yacht two decades after her launch. The conversion works include a five-meters extension, a restructuring of the top deck and an entirely new interior.

10.  90-meters LAUREN L

Built by Cassens-Werft in 2002, LAUREN L began life as a cruise ship sailing under the name Constellation. After four years in service, she was bought by Liveas Yachts who converted her into a modern charter yacht for a maximum of 40 guests on board.
