M/Y A+, formerly known as Topaz[3], is a luxury motor yacht constructed by Lürssen in Bremen, Germany.[4] The yacht's interior was designed by Terence Disdale Design and the exterior designed by Tim Heywood. The boat was launched in May 2012.[5] Topaz ties with Prince Abdulazizis for the title of world's fifth largest private yacht, both holding a length of 147 metres (482 ft). The vessel beats the world's sixth largest private yacht, El Horria, in length by 1.28 metres (4 ft 2 in).[6]


The 147 metres (482 ft) long ship has a beam of 21.50 m (70.5 ft) and has a gross tonnage of 11,589.[5] The yacht's cost has been estimated at 400 million (approx. $527 million.)[7] A+ was built in the same German shipyard as the Azzam, the world's largest private yacht.[8]

The vessel features a steel displacement hull, an aluminium superstructure and consists of eight decks.[5][7] This yacht was originally being built in a 169 m (554 ft) dry dock but to complete the project, the yacht had to be taken to a 220 m (720 ft) dock to be built alongside.[9] A+ is also the world’s sixth largest luxury yacht, launched in 2012.[10]


The main engines are twin Pielstick diesel engines, each with power of 7990 hp. This is enough power for the yacht to reach a service speed of 22.9 knots, while the maximum speed is over 25.5 knots. The yacht is also equipped with two diesel generators and an emergency diesel generator. These aggregates provide power to the stabilisers, navigation equipment and all the facilities on board.


A+ is equipped with zero-speed stabilisers, jacuzzi (on deck), double helicopter landing pads, swimming pool, tender garage, swimming platform, air conditioning, underwater lights. There's also a fitness hall, cinema and a large conference room.
