Water craft, such as a boat or a ship

Abstract

This invention relates to a watercraft with a framework arranged in radial symmetry to a central horizontal axis (Z-Z), in which a passenger cell and/or a load absorbing cell is movably mounted so that it retains its vertical suspended position in rotational movement of the framework. According to this invention, the passenger cell and/or a load absorbing cell has an arrangement for attaching at least one sail ( 1 ).
