MaSS is the successor of Wrecks in Situ (WIS), an interactive website designed to increase access to underwater cultural heritage for the general public. WIS came forth from MACHU, a three-year project on managing cultural heritage underwater.
The redesign of WIS is an initiative of the Maritime Program of the Cultural Heritage Agency of the Netherlands.

MaSS was designed and built in Utrecht by Ylab designers for interaction.
