I believe there is an important vocabulary issue here. As far as I understand, the word "wing" usually associated with "flying". From that perspective; birds have wings, aeroplanes have wings but not F1 cars or boats or anything that does not fly. In other words, wings are used to create a lift for flying objects in air. Boats are kept on water thanks to a lift from water not air, therefore they do not need wings for lift.

However on different vehicles wing-like structures exists to serve different purposes, mostly efficiency (low air friction), stability and control. Any vehicle that goes faster than certain speed can have wing-like structures, this includes ordinary and sports cars, F1 cars, racing boats etc. As mentioned in one the comments above to get any force from a wing-like structure in air, either the flow has to be fast (high speed) or the area of the wing-like structure has to be large (such as windmills). I believe, engineers make calculations for the compromise between the size of the structure and the gain and build wing-like structures on vehicles where necessary. These parts are not always called wings. See attached pictures.
