Woah, four fins? How many fins can I have on my surfboard at one time? Five? Six? What is the limit? Four (generally). Quads (or four fin set-ups) are self-generating speed machines. Pairing two large front fins with two smaller trailer fins creates a channel through which water can flow unobstructed, maximizing speed. Removing the rear center trailer fin typical of a thruster set-up eliminates drag caused by that center fin. Whether you’re surfing two, or twenty-two foot waves, quad sets provide speed, stability, and versatility ideal for any and every condition. Rider Shack offers a complete selection of both basic and premium quad sets from FCS, FCS II, and Futures. Discover a quad set that’s right for you!
