Five facts and figures to know about the Manta

by The Sea Cleaners 1 Mar 2021 05:02 GMT

Three years of research and development and tens of thousands of hours of work were necessary to conceive the final design of the Manta and integrate all its technological innovations.

The result?

A one-of-a-kind sailboat that removes pollution from the oceans:

  • reconciling performance and energy sobriety,
  • intervening on both the corrective and preventive levels,
  • providing a complete and versatile response to the scourge of plastic pollution.

This ambassador boat will also aim to change the way people consider plastic pollution, by showing that solutions exist in the face of this ecological disaster, and that collection and recovery technologies are effective, affordable and economically viable.
