Airplanes deploy revers thrusters when landing which are basically just shaped metal shields that move into place behind the engines to provide reverse thrust and slow the plane.

But adding a fan on a sailboat is seen as stupid and doesn’t work.

    It depends on the actual situation or maneuver during sailing. It’s a mix between the wing effect and the ancient principle “wind from behind is pushing the boat forward”.
