Catamaran Impi

Hello everyone from the brown Kourou river! Nevertheless a spectacular dawn, with a chorus of bird song. A little later this interesting craft with Ariane 6 on board came cruising past Impi. Ariane 6 will have the flexibility to launch both heavy and light payloads to a wide range of orbits for applications such as Earth observation, telecommunication, meteorology, science and navigation. How do they keep the boat so white going up and down this muddy river????
