Quad vs Thrusters
What is the difference between tri fin and quad fin set ups? This is a huge question that is coming up more and more often as we now see new surf boards with 5/4/3 fin set ups. The 5/4/3 setup is a setup that has 5 fin boxes that allows a surfer to choose between 3 fins or 4. Question is, which set up is right for you?
Let’s start by identifying the performance difference between these two setups. The tri fin, or thruster, setup is the classic fin setup. It features three fins creating the shape of a triangle, one stabilizer fin in the back and two more in front of the stabilizer close to the rails. This setup is made for speed control; the center stabilizer fin creates drag which is an important action for controlling your speed. The quad fin setup is used to be more maneuverable and faster than a thruster setup. Believe it or not the quad fin setup is less restrictive than a thruster which really helps for quick accelerations when taking off on a wave. Also another benefit over the thruster is its more maneuverable and turns quicker and feels more “skaty”, or loose, due to the lack of a center stabilizer fin. Read more
