Madame Gu, a 99m/325 ft yacht, was built by the Feadship yard in Makkum in 2013. Upon her delivery, she held the title of being the largest superyacht ever built in the Netherlands. In 2014, she was awarded Superyacht of the Year.

Before creating the detailed 1:20 scale drawings for the crew and luxury areas, SDSI collaborated closely with the yard and Struik & Hamerslag to produce mock-up drawings. Once the mock-ups and details were approved, we proceeded with the 1:20 scale drawings. Madame Gu was designed by Andrew Winch Designs, who were responsible for both the interior and exterior. We held regular meetings with Andrew Winch Designs and the yard throughout the process.

SDSI also produced all the crew area production drawings, marking the largest production drawing contract for SDSI at that time.
