We will explain the foil of the ``QUAD rear fin'', which is divided into two major parts. First, let's take a look at the familiar tri-fin shape. The front side fins are The inside is flat and the outside, on the rail side, is curved. These side fins are shaped like a "foil" so that they can bend when turning. A foil designed to bend is called a side fin foil or flat foil. The center fin of this tri-fin is curved on both sides. Of the three tri-fins, only one has a different shape, so you can easily tell the difference when attaching it to your board. This fin, which has curved surfaces on both sides, is called a CENTER FIN foil. The fins attached to the two rear wheels of the QUAD can be broadly divided into two types. "Side Fin Foil (FLAT)" and "Center Fin Foil (50/50)". The "Side Fin Foil" has good turning ability and turns inwards when turning. This "center fin foil" gives you a longer turn and more drive. So, the board you ride in QUAD according to your preference and wave quality is, It is recommended that you understand the characteristics of the QUAD rear fin foil before selecting and using it. The side fins usually have a FLAT foil ratio of "curved 100/0 flat", ↑I feel like I want to try using "80/20" like this. There's also a foil quad rear fin with interesting proportions.
