Its core is manufactured from high‑modulus carbon, producing an ultra‑thin, highly streamlined profile (8.8% thickness — 8.8 mm at a 10 cm chord) that minimizes drag in all sailing directions. Select’s Active Flex concept delivers a precise balance of flex and twist: a rigid trailing edge with a responsive leading edge that absorbs lateral loads and twists dynamically to create a very vertical lift. This reduces wetted hull surface and delivers exceptional control, stability and comfort at high speeds. Built for boards in the 85–145 L range, the M88 Superfast unlocks maximum top‑end performance for experienced sailors seeking aggressive acceleration and reduced resistance. The fin mounts in a standard Deep Tuttle box and is designed to hold up under repeated high‑load use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh‑modulus carbon core for maximum stiffness-to-weight ratio and durability  \u003c\/li\u003e\n\u003cli\u003eUltra‑thin hydrodynamic profile (8.8% thickness) for minimal drag and improved top speed  \u003c\/li\u003e\n\u003cli\u003eActive Flex geometry: rigid trailing edge with a torsionally active leading edge for dynamic lift control  \u003c\/li\u003e\n\u003cli\u003eVery vertical lift characteristic reduces wetted surface and hull drag at planing speeds  \u003c\/li\u003e\n\u003cli\u003eOptimized for speed and slalom boards between 85–145 liters  \u003c\/li\u003e\n\u003cli\u003eDeep Tuttle box compatibility for secure, high‑load mounting  \u003c\/li\u003e\n\u003cli\u003eEngineered for experienced riders seeking high‑speed stability and precise tracking  \u003c\/li\u003e\n\u003cli\u003eDurable composite construction designed to withstand repeated high‑stress 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: SML07512031\u003cbr\u003e\nMaterial: High‑modulus carbon core with composite layup\u003cbr\u003e\nSize\/Dimensions: 31 cm fin length; ultra‑thin profile (8.8% thickness — example 8.8 mm at 10 cm chord)\u003cbr\u003e\nWeight: Not specified by manufacturer\u003cbr\u003e\nColor: Carbon \/ natural carbon finish (as pictured)\u003cbr\u003e\nCategory: Fins\u003cbr\u003e\nAge Group: Adults\u003cbr\u003e\nGender: Unisex\u003cbr\u003e\nMount: Deep Tuttle box compatible\u003cbr\u003e\nRecommended board volume: 85–145 L\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIdeal for advanced and professional windsurfers and racers who demand maximum speed and precision.
