It is a small yellow catamaran with a central nacelle to accommodate the piloting and communication system, as well as a scientific PC and most of the instruments. This nacelle is crossed by a lifting keel which serves as a support for the submerged instruments (depth sounder, physico-chemical sensors, sampling pipe).
The two floats contain the batteries and are fitted at the rear with small electric motors.
