MY Fountainhead is an 87.78m/288 ft Feadship yacht built at De Vries Makkum and launched in May 2011. While MY Fountainhead shares significant exterior similarities with MY Musashi, its interior is entirely unique. Sinot Exclusive Yacht Design served as the interior architect, with Axel Vervoordt having a significant influence on the interior styling, including art, furniture, and materials.

SDSI produced all the 1:20 scale drawings as well as the production drawings for several luxury and crew areas. The collaboration between the architects, yard, and SDSI during the project was exceptionally close.
