A trimtab is a very small, unassuming piece of equipment on ships and aircrafts. It’s the small rudder on the larger rudder, and at first it doesn’t look like much. It almost looks insignificant. But it’s a metaphor for something much larger. The trimtab takes almost no effort to move, but it creates huge impacts far beyond its size. It’s literally what pulls the larger rudder; It's what guides the ship, no matter how big it is. At the end of the day the trimtab is the actual source of how all direction and balance is achieved.
