1. A marine vessel, comprising:
inboard electric motors with propellers, the electric inboard motors accommodated in skegs underneath a marine vessel;
waterjets to produce jets of water, the waterjets arranged under a bottom of the marine vessel;
a flow channel for the jets of water emitted from the waterjets formed between the skegs and behind the waterjets, the flow channel to start in an area at the bottom of the marine vessel, and to rise with a continuous profile towards a stern of the marine vessel; and
a guide wedge arranged in the front part of the flow channel having an apex to point towards the stern of the marine vessel and an approximately triangular cross section with the result that the jets from the waterjets are concentrated in the center of the flow channel between the propellers of the inboard motors.
