摘要： A seagoing boat is driven by at least two rudder propellers and has a hull for transporting cargo or passengers. The rudder propellers are preferably embodied as electric rudder propellers. The hull has an approximately rectangular cross section amidships, to which flow-directing bodies are connected. A flow channel is configured between the skegs, the flow channel being embodied in a wedge-shaped manner with a continuous, preferably slightly bent enlargement in the direction of the bottom astern. The side walls of the flow channel are configured at least in part as even surfaces and taper off in the form of fin-shaped teeth having water displacement volume. The streaming effect of the flow channel generates a low boat resistance. The influence of the flow channel on the wake has a positive effect on the propulsion efficiency.
