Patent abstract
The rudder post (40) for rudders for water vehicles has end sections (41, 42) made of a metallic material, in particular of wrought iron, and a mid post section (45) made of a nonmetallic material connected with the end sections so that the rudder post has a relatively low weight even for a very big length by maintaining a high flexural strength and torsion stiffness.
