ABSTRACT:
A catamaran has two hulls each having longitudinal axes with reference to which the hull is asymmetrical. The hulls are located at opposite sides of a longitudinal symmetry line of the catamaran and the axes of the hulls are longitudinally inclined relative to this line, so as to diverge away from this line either in forward or in rearward direction of the catamaran. Each hull has at least one propeller shaft which extends substantially parallel to the symmetry line and which has a shaft portion projecting from the hull and located either adjacent the outwardly or inwardly facing side of the hull, where it carries a propeller.
