Adjustable Fins

Force Fins has been designing fins for over 35 years, and with millions of satisfied customers, they can honestly say that they are the experts in fin design. That’s all they do, and they think their innovative fins are without equal in terms of comfort, efficiency, durability, performance, versatility, and sheer value for your money. All their fins take advantage of the laws of nature and physics – and common sense. Force Fins are extremely efficient because they understand the hydrodynamic advantages of flapping foils, thrust-producing vortex, lift forces, and material rebound, and they include these state-of-the-art concepts into every fin they design. Their Force Fin has been tested in Boeing’s wind tunnel and shown to have wingtips that form a perfect hydrofoil, offering turbulent free water flow. Our work was an inspiration to the designers of the fastest and most revolutionary keels. They have since been asked to apply their fin technology to increase the speed and efficiency of oceangoing ships! Each fin is individually handcrafted in the USA and manufactured from exclusive versions of polyurethane that are resistant to ultraviolet radiation, abrasion, and chemicals. The high-quality materials they use give our fins their snappy blade action and extreme durability. Force Fins will last for years, even when worn daily.
