In short
Yas is a 141-metre motor yacht built on the steel hull of HNLMS Piet Hein, a Kortenaer-class frigate that Koninklijke Schelde launched for the Royal Netherlands Navy in 1978 and that later served the UAE navy as Al Emirat (Boat International, YachtBuyer). ADM Shipyards in Abu Dhabi rebuilt her under the project name Swift 141, lengthened the hull by about 12 metres and relaunched her in 2011; Boat International gives delivery as 2012 in its directory and 2015 in a later feature (SuperYacht Times, Boat International, Boat International). Pierrejean Design Studio styled her inside and out, with a dolphin-inspired profile and a glass dome housing the bridge and the owner's suite (Boat International). She was the first yacht built to the UAE Large Yacht Code, carries up to 60 guests and has a top speed of 26 knots (SuperyachtNews, SuperYacht Times); she is not believed to be available for charter (YachtCharterFleet).
