This is the original template for the Merrick Twin Fin "MTF", made by FCS to use with the FCSII fin system. The design, when hooked up with a small trailing center fin, makes a great loose feeling thruster. You get the speed of a twin-fin with the positive drive of a tri-fin. (Side fins are the same template as used on the new CI Twin Fin)

- Height: 5.63"

- Area: 20.43"

Center fin:
- Height: 3.74"
