The optimal combination of draft, beam, length and capacity will make it possible for these ships to moor, load and discharge in harbours with a limited infrastructure. Thanks to the large crew, the yards, the rigging, and the capstan, the cargo can be worked independently in ports of this sort.
The three masts and square rig, combined with a well-balanced underwater body, will give this prototype the maximum possible propulsion power an emission-free ship can achieve. By not being propelled by mechanical means, the investment of an engine room is saved, while it is made possible to optimally exploit the daily meteorological circumstances and seasonal weather patterns. Above all it guarantees maximal sustainability.
