How Do Bennett Marine Trim Tabs Work?





How Do Bennett Trim Tabs Work?



Properly sized trim tabs improve the performance of your boat in a much wider range of weight, weather and water conditions. The purpose of trim tabs is to recreate your ideal running attitude, even on a rough day.

Think ailerons and elevators on an airplane. Trim tabs do much the same thing for a boat - providing lift to compensate for changing conditions.

How Trim Tabs Work

Three variables combine to affect lift:

  • Size of the trim tab surface

  • Angle of deflection

  • Water-flow over the tab (caused by speed of the boat)


  • When the helm control is pressed, the trim tabs move into position. When they are deflected downward, the water force on the trim tab surface creates upward pressure, raising the stern and lowering the bow.

    The principle is simple. The results are impressive.




    Reverse Operation Don't Worry About Which Trim Tab is Moving
    Bennett Trim Tabs operate the reverse of what you might think. The port trim tab lowers the starboard bow. Conversely, the starboard trim tab lowers the port bow. The control is wired so that all you have to do is press the control in the direction you want the bow to move. The proper use of Bennett Trim Tabs becomes second nature after a short time.
