The Mayflower Autonomous Ship (MAS), which had to abandon its transatlantic crossing in June due to a mechanical fault, has been relaunched ahead of a next attempt at a UK to US voyage in spring 2022.
With the vessel back in the water, the MAS team said it will resume its testing and scientific research schedule.
A series of cruises along the UK coast are planned for this autumn and winter, before the next attempt on the Atlantic crossing.
