MY Promise is a 51m/ 167 ft Feadship built as the first ice-class vessel, at De Vries Aalsmeer in 2018. Interior architecture by Bannenberg & Rowell Design; exterior by Studio De Voogt. This was the first project with all the boxdrawings in the scope of SDSI. Before the boxdrawings SDSI made all the arrangements drawings. After delivery to De Vries, they made 1:20 and production drawings based on the boxdrawings.
