Description:
Introducing the next evolution in carbon freediving fins. Created in collaboration with Yamamoto™, our new fins combine Alchemy’s precision engineering with Yamamoto’s Aurora® technology, delivering superior hydrodynamics, unrivalled build quality, and a visual transformation that captivates in the deep. Engineered with state-of-the-art materials and meticulous craftsmanship, these fins offer lightning-fast response and robust design, making them the go-to choice for freedivers who push the limits. Tested and trusted by elite athletes, they redefine the boundaries of what’s possible underwater.

Aurora Technology:
Yamamoto’s Aurora® technology was designed to inject light and color into a world often dimmed by negativity. Its unique, color-shifting properties come to life both above and below the water, transforming every dive into a vibrant, immersive experience. Aurora® fins create a stunning visual effect in underwater content, making freedivers look and feel extraordinary and ensuring they stand out effortlessly. When combined with an Aurora® wetsuit, the result is a captivating, otherworldly display that’s impossible to overlook—a truly unique and mesmerizing experience for both the diver and those watching.

Carbon Layers:
These fins feature an advanced carbon layer configuration within each blade. Fifteen layers of premium, EU-made, 100% carbon fiber—specifically selected for deep-sea applications—are expertly positioned to deliver an exceptional bending profile, offering superior feedback, precision, and speed. The first-ever V-shaped reinforcement layer extends beyond the blade’s angle, channeling raw power right from the start of every kick, ensuring maximum efficiency and responsiveness for deep-diving performance.

Choosing the right Stiffness:

Choosing the correct stiffness and footpockets for your fins can feel overwhelming, but we’re here to help. Alchemy fins come in five different stiffness levels, each suited for varying body types and applications. Whether you’re looking for maximum power or a softer, more flexible blade, selecting the right stiffness ensures optimal performance and comfort in the water. By matching the right stiffness to your body type and diving style, you’ll experience greater efficiency and control. Here’s how to get it right.

Construction:

Expertly engineered to meet the most demanding standards, each fin is crafted in controlled environments with consistent ambient temperature and humidity. Using 45 tons of pressure and vacuum-assisted resin transfer molding (VRTM), they undergo 12 hours of post-curing with precise temperature control, managed by a PLC system with a deviation of less than ± 0.1°C. From start to finish, the entire production process is powered by renewable energy sources, ensuring not only top-tier performance but also a commitment to sustainability.

Lead Time:

Alchemy fins are custom-made to order and not kept in stock. The standard lead time is approximately 3-5 weeks, though it may vary depending on the workload. To ensure timely delivery, we recommend reaching out to confirm the current lead time before placing your order.

Blade Ending Shape

The blades are designed with a dolphin tail-shaped (D.Tail) ending, engineered to provide maximum thrust with minimal energy consumption. Based on hydrodynamics studies (Rensselaer Polytechnic Institute / T. Wei) and rigorous testing in Computational Fluid Dynamics (C.F.D.) software, this design mimics the natural efficiency of dolphin movement, delivering superior performance. The D.Tail shape harnesses the flow of water to enhance speed and power, making every kick more effective with reduced drag.

Features

Aurora® fins are available at either a 23-degree or 30-degree angle. The 23-degree angle pairs with Pathos Fireblade or Cetma S-Wing foot pockets, while the 30-degree angle mounts on C4 (250, 300, 400) or Mares X-Wing foot pockets. Both options deliver reduced effort and oxygen consumption with precise hydrodynamics. The fins feature a striking Aurora® coating with a mirror finish on the front, and a matte finish on the back. Each fin includes a unique serial number embedded into its lamination, guaranteeing authenticity.

Water Rails

Our hydrodynamic water rails, made from 100% high-performance silicone, are precision-engineered using 3D CAD technology and manufactured in the UK. Extensive C.F.D. testing has shown that these rails effectively channel water along the blade without losing their shape, even under extreme bending conditions. Unlike rubber, silicone excels in maintaining strength and structure, ensuring optimal water flow from the start of every stroke and delivering an immediate response to the diver’s movements.
