Its core structure is built from high-modulus carbon to produce an ultra-thin foil profile (8.8% thickness), minimizing drag and allowing the fin to slice through the water with exceptional efficiency. Select's Active Flex concept balances a rigid trailing edge with a dynamic, twist-capable leading edge, producing a vertical lift effect that reduces hull wetted area and stabilizes the board at high speeds. This combination of stiffness and tuned flex delivers precise handling, predictable release and outstanding top-end performance. The fin is optimized for experienced sailors riding 85–145 L speed and slalom boards and is supplied in a Power Box configuration for straightforward mounting. Durable carbon construction ensures long-term stiffness retention and resistance to fatigue under high loads. For best results pair with Power Box-equipped speed\/slalom boards and proper footstrap setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-modulus carbon construction for superior stiffness-to-weight ratio and durability  \u003c\/li\u003e\n\u003cli\u003eUltra-thin foil profile (8.8% thickness) to minimize drag and maximize speed  \u003c\/li\u003e\n\u003cli\u003eActive Flex design: rigid trailing edge with a twist-capable leading edge for controlled vertical lift  \u003c\/li\u003e\n\u003cli\u003eReduces hull wetted surface for improved acceleration and top speed  \u003c\/li\u003e\n\u003cli\u003eOptimized for speed and slalom boards in the 85–145 L range  \u003c\/li\u003e\n\u003cli\u003ePower Box compatible for secure, standardised mounting  \u003c\/li\u003e\n\u003cli\u003eEngineered for experienced sailors seeking high-speed stability and precise control  \u003c\/li\u003e\n\u003cli\u003eLow-drag shape that performs across a range of sailing angles and conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eManufacturer: Select\u003cbr\u003e\nSKU: SML07510031\u003cbr\u003e\nMaterial: High-modulus carbon composite\u003cbr\u003e\nSize\/Dimensions: 31 cm length; ultra-thin foil profile — 8.8% thickness (8.8 mm per 10 cm chord)\u003cbr\u003e\nWeight: Not specified by manufacturer\u003cbr\u003e\nColor: Natural carbon finish (black)\u003cbr\u003e\nCategory: Fins\u003cbr\u003e\nAge Group: Adults\u003cbr\u003e\nGender: Unisex\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIdeal for advanced and professional windsurfers targeting speed and slalom disciplines.
