Sailing Yacht A is an auxilliary schooner built in Kiel by Nobiskrug for Andrey Melnichenko. Her 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 vessel features an underwater observation pod in the keel with 30cm-thick glass. S/Y A is the largest private sail-assisted motor yacht in the world.
S/Y A was delivered by Nobiskrug on February 3rd, 2017 and left Kiel on February, 5th, 2017.  She exited the Baltic Sea in light mode on near-empty fuel tanks in order to clear the Drogden Strait with minimum draught. She is undergoing further sea trials and final fitout at the Navantia shipyard in Cartagena, Spain. According to Boat International and SuperYacht Times, the handover to its owner is planned for the late spring 2017.
