The Futures Alpha Large fins are thruster fins based on the classic Al Merrick (Channel Islands) template, designed for heavier surfers or those looking for a set with more control, drive and stability. This Large (+75 kg) size model belongs to the Rake category, ideal for surfing long lines, drawn-out turns and solid projection on the face.
The Alpha (NetPlus®) construction is made in Huntington Beach, California, combining recycled fishing nets recovered from the ocean with Futures’ Compound 6 (C6) technology, which incorporates carbon and air infusion. The result is a light, durable fin with a responsive flex that enhances performance in all kinds of maneuvers.
