In order to provide a rudder blade with a rudder blade hub, which, in comparison to rudder blades known from the prior art, has a lower overall weight and can be produced with a reduced outlay on materials and costs, while simultaneously ensuring a sufficiently high strength in order to be able to absorb the large forces and torques acting during operation of the rudder blade and to be able to conduct them away to a rudder stock, it is proposed to make provision, in the case of a rudder blade (100), in particular in the case of a semi-balanced rudder or a full spade rudder, for water crafts, in particular ships, comprising a leading edge (10), a trailing edge (11), a first side wall (12) and a second side wall (13) lying opposite the first side wall (12), and a rudder blade hub (17), which is arranged in a connection space (16), for connecting a rudder stock, wherein the rudder blade hub (17) comprises a hub body (29), wherein the hub body (29) comprises an inner bore (30) for receiving a rudder stock, and a hub outer surface (31) running in the circumferential direction, for the hub outer surface (31) to be arranged in its entirety spaced apart from an inner side of the first side wall (12) and from an inner side of the second side wall (13).

    Il est décrit un safran pour des navires deau comprenant : un bord d'attaque, un bord de fuite et un premier mur latéral, ainsi quun deuxième mur latéral opposé au premier mur latéral; et un moyeu de safran disposé dans un espace de liaison pour la liaison dune mèche de gouvernail; lespace de liaison étant fourni à lintérieur du safran, le moyeu de safran comprenant un corps de moyeu, le corps de moyeu comprenant un orifice intérieur pour la réception dune mèche de gouvernail, et une surface de moyeu extérieure dans la direction circonférentielle, la surface de moyeu extérieure totale étant disposée de manière espacée dun côté intérieur du premier mur latéral et dun côté intérieur du deuxième mur latéral.
