Known before as project Gisele, the semi-completed vessel arrived at Balk Shipyard in the Netherlands in 2015 where she was completely stripped down and lengthened to her current measurements. The vessel was essentially cut in half – twice. A precise incision amidships and another aft made it possible to add roughly four metres of new ship to Sandalphon. Azure Yacht Design & Naval Architecture developed the new design and naval architecture of the rebuilt vessel, including the custom interior.
