The invention relates to a bearing for supporting a shaft, in particular a rudder shaft, or a rudder blade, by means of which bearing the bearing clearance or the bearing wear can be continuously monitored, determined, and optionally documented. According to the invention, for a bearing for supporting a shaft, in particular a rudder shaft, comprising a first bearing element and a second bearing element, wherein the first bearing element has a sliding surface for contacting the second bearing element in a sliding manner, and a measurement-value sensor having a wear surface for contacting the second bearing element in a sliding manner, the at least one measurement-value sensor is not pin-shaped.

A device for maneuvering a watercraft includes a rudder trunk and a receiving shaft, wherein a first part of the rudder trunk is disposed in the receiving shaft in such a manner that there is an intermediate space between the first part of the rudder trunk and a wall of the receiving shaft. A second part of the rudder trunk projects from the receiving shaft, wherein the intermediate space has an apparatus for clamping the first part of the rudder trunk over a clamping height. A method for manufacturing a device for maneuvering a watercraft is also provided, wherein the manufacturing expenditure for the rudder trunk is reduced and the installation process of the rudder trunk is simplified.

In order to achieve improved properties for a fin for a rudder for water vehicles, the fin is at least partially made of a fiber-composite material. The body for the fin has one or more separated inner hollow areas which are filled with a filler material. The fin body has a front leading edge facing a rudder, a rear trailing edge facing away from the rudder, and stiffening elements arranged between both edges.

A rudder for ships having a rudder blade which has a leading edge and a trailing edge. The rudder blade has two superimposed rudder blade sections; the leading edge sections of which are offset such that a first leading edge section is offset port or starboard and a second leading edge section is offset starboard or port. The first leading edge section has a port-sided offset surface which projects over the second leading edge section, and the second leading edge section has a starboard-sided offset surface which projects over the first leading edge section. A flow body is configured so that its dimensions are adapted to the dimensions of the offset surfaces. The flow body covers the offset surfaces and is arranged in the area of both offset surfaces.

Rudder for ships

In a rudder for ships composed of a rudder blade with a rudder post () held and supported in a rudder trunk (), the rudder trunk () is made of a fiber composite material and is inserted into a nautical outer trunk tube () made of steel or of another appropriate material prepared by a shipyard, extending into the lower edge of the head box and inserted into the rudder blade (). After alignment of the rudder trunk () in the nautical trunk tube (), the intermediate space between both components () is cast with a cast resin, or both components () are bonded together.
