Why do surfboards have fins on the bottom?

Like a full-size sailboat with a bottom keel or small boat with a rudder, fins provide the rider with stability while the surfer shifts weight and their stance to steer the board. The center fin on the tail of your board creates a pivot point which helps with desired maneuverability and flow when riding a wave.
