Calypso II

Fifty years of experience with Calypso and Alcyone enabled Captain Cousteau to define a list of specific tasks for Calypso II. The ship itself is conceived as a laboratory for non-polluting technology. Innovations include the shape of its hull as well as the combination diesel-Turbosail propulsion system, navigation equipment and computerized monitoring networks. Calypso II will be spacious enough to house scientific laboratories and exploration systems (observation chamber aft, helicopter, autonomous submersible, seaplane). An environmental observatory.
