RUDDER AND SHIP-LIKE OBJECT HAVING SUCH A RUDDER

摘要

The invention relates to a rudder for maneuvering a ship-like object, the rudder comprising a main rudder blade having an upstream end and a downstream end, the rudder being rotatably mountable to the ship-like object around a rotation axis that generally extends in a vertical plane. The main rudder blade extends generally upright. The rudder comprises two generally upright extending auxiliary rudder blades connected to the main rudder blade by transverse plates. At least one of the transverse plates is oriented generally obliquely upwards towards a downstream end. The transverse plates thereby follow the orientation of the flow of water below the upwards receding aft body of the ship.
