Sailing Yacht A is a sailing yacht launched in 2015. The vessel is a sail-assisted motor yacht designed by Doelker + Voges (exteriors), Philippe Starck (interiors, exteriors) and built by Nobiskrug in Kiel, Germany for the Russian oligarch billionaire Andrey Melnichenko.
Its propulsion consists of a variable-speed hybrid powerplant with two lineshaft controllable-pitch propellers that is sail-assisted by a three-mast fore-and-aft sailing rig. The freestanding carbonfiber rotating masts were manufactured by Magma Structures at Trafalgar Wharf, Portsmouth. Doyle Sailmakers USA manufactured the three fully automated carbonfiber/taffeta full roach sails. The furling booms were built in Valencia by Future Fibres. The rigging of this yacht was developed partially to be implemented on cargo ships and to be used for commercial use. The vessel features an underwater observation pod in the keel with 30 cm (12 in)-thick glass. It is the largest private sail-assisted motor yacht in the world.
Sailing Yacht A was delivered by Nobiskrug on February 3, 2017, and left Kiel on February, 5, 2017. It exited the Baltic Sea in light mode on near-empty fuel tanks in order to clear the Drogden Strait with minimum draught. It underwent final sea trials and the final fit-out at the Navantia shipyard in Cartagena, Spain. According to media reports, Sailing Yacht A was handed over to the owner on May 4, 2017 in Monaco by the project team led by Dirk Kloosterman having completed her final sea trials in the Navantia shipyard at Cartagena, and final tests and inspections at Gibraltar.[deprecated source] Boat International called it "the boundary pushing superyacht".
