The document summarizes the goals and technology behind the Mayflower Autonomous Ship (MAS). The MAS is intended to autonomously retrace the route of the historic Mayflower voyage to advance marine research and autonomous ship technology. Key goals are to create a cost-effective platform for scientists to gather ocean data and demonstrate a fully autonomous, crewless ship navigated by an "AI Captain" using sensors and decision-making software. The MAS completed a successful 3,349 mile transatlantic journey in 2021 without human captain or crew to prove the capabilities of autonomous ship technology.
