The Moloko Flexi Thurster US Fin is a 3.5-inch long fin that fits all US fin boxes that are found across a range of board sports including Stand Up Paddleboards, Surfboards, Windsurf boards and more.
Made from a hard-wearing durable plastic that offers a small amount of flex, this 3.5-inch long fin works well as a very short thruster fin. It does also work well as a shallow river fin but offers very little in the way of lateral stability and control.
The stock of the fin (the bottom part locates in the fin box) measures 8 inches overall in length.
