The Manta

A revolutionary vessel to clean our oceans


70 m long – 49 m wide – 61 m high

The MANTA is the first deep water vessel capable of collecting large quantities of macro plastic waste from the sea.

The vessel’s design is centred around the most innovative technologies in terms of clean energy production. It is autonomous and has excellent manoeuvrability, enabling it to rapidly intervene in the most polluted areas; in deep water, along coasts or in the estuaries of the ten great rivers from which 90% of all plastic waste reaches our oceans.


To achieve the smallest possible carbon footprint, the MANTA will be propelled by DynaRig sails and four electric motors. These motors will be powered by a number of combined renewable energy technologies, associated with an optimised energy storage system.

Its hybrid propulsion system gives the MANTA the mobility required to rapidly reach the drifts of plastic waste while they are still concentrated by wind and water currents and before they set off on their oceanic voyage towards the “plastic continents”.

The MANTA can intervene across the world, rapidly reaching the zones of densest pollution, whether these are along coasts, in estuaries or on the high seas, enabling the collection of floating macro plastic waste before it sinks to the bottom of the sea.

The vessel’s major energy production and storage capacity, with 100 tonnes of batteries, and its hybrid propulsion system, involving both sail and electric motors, provides the MANTA with maximum autonomy for its travel and collection phases.


To collect, sort, compact and store plastic waste

A unique ocean-going collection system

The MANTA’s waste collection system is the focus of a great deal of attention. Our design offices have produced an innovative and efficient solution. The three collectors are located between the vessel’s hulls, rapidly bringing aboard the waste for manual sorting.

Protection of marine fauna

During its collection phases, when the MANTA travels at around 2 knots, its audio emission system will divert cetaceans and other fish from its route, preventing them from being captured accidentally.

600 m³ of storage capacity

The plastic waste will then be transported by a conveyor system to the manual sorting area where the reusable plastic waste will be separated from other debris and compacted into 1m³ bales. The MANTA can store 250 tonnes in its hulls, and this waste will then be taken back to land for recycling.

A source of shared data

To improve knowledge and reinforce the prevention of pollution, the MANTA is equipped with a complete scientific laboratory which will enable the waste to be studied in terms of geolocation, quantity and quality. The data will be provided to the entire international community as open data.

Larger floating debris

With its two powerful cranes, the MANTA can also remove larger floating debris from the water, such as nets or containers lost by other vessels or debris from the land. This can be stored onboard before destruction on land in specialised units.


Its combination of technologies for propulsion, the production of clean energy and emissions for which it is destined makes the MANTA an original and complex vessel. A unique innovation for a unique project.

The technical consortium

A technical consortium has been assembled to accept the technological challenge represented by designing and constructing the world’s first giant macro plastic waste collection quadrimaran.

The consortium consists of providers and partners who have all been keen to supply the project with their unique expertise and human and material resources.

Feasibility studies

The first phase of the project has been undertaken by Stephan Vallet’s V-Design naval architecture design agency, which has carried out the feasibility studies for the MANTA.
