SunStone Ships is launching a new series of ships and is on the verge of signing a contract with a shipyard.  

The new Boundless class will consist of 10 cruise ships (four firm ships and six options). SunStone Maritime Group chief executive Niels-Erik Lund tells PST the new shipyard is not China based. The shipowner used China Merchants Heavy Industry to build its Infinity-class vessels.
