What happens when an extra 10cm gets added to the iconic V3-30? Meet the V330 Plus. Designed for special operations, these state-of-the-art carbon fins accelerate your performance by providing supercharged power and immaculate style. A product of collaboration with some of the world’s deepest humans and utilizing next-generation materials and supreme craftsmanship, they are the most powerful pair of fins we’ve ever made. Armed with lightning-fast response, they are designed to outdo the competition even in the most demanding scenarios.
These groundbreaking blades feature a 30-degree angle. Such an angle requires less effort from the diver when kicking, which practically translates to less oxygen consumption. Combined with the extra 3 degrees that C4 (300 & 400) foot pockets offer, the fins’ effective angle totals 33 degrees. This combination offers an “early start” of the blades’ working spectrum and makes them feel softer than they really are. The blades also feature an extraordinary mirror finish on their front side and a matt finish on the back. Their unique serial number tag is embedded into the blades’ lamination, ensuring the authenticity of your Alchemy product along with a hologram tamper-proof individually numbered tag on your warranty certificate document.
V3-30 Plus feature the ultimate carbon layer positioning within each blade. Fifteen (15) layers of premium, EU-made, 100% carbon fiber, selected especially for deep sea applications, are positioned in an exceptional way, in order to offer an unbelievable bending profile, with the ultimate feedback, nerve, and speed. Having the first ever V-shaped reinforcement layer that goes beyond the blade's angle, raw power comes straight from the beginning of each and every kick.
V3-30 Plus are equipped with a groundbreaking pat. pending design, Hardtip™. Built in reverse order, we managed to get the blade's tip harder, and maximized efficiency by correcting the total bending profile, thus ensuring zero dead spots during immersion. While it doesn’t affect the blade's overall stiffness level, Hardtip™ kicks in when the fins start oscillating continuously during a diver's vertical movement, ensuring continuous power transition without energy loss.
V3-30 Plus are manufactured in compliance with the most demanding standards in constant ambient temperature and humidity. 45 tons of total pressure combined with vacuum assistance (VRTM) and 12 hours post-curing in temperatures controlled through PLC (Programmable Logic Controller) with a deviation of less than ± 0,1°C.
V3-30 Plus blades end in a dolphin tail shape (D.Tail). This shape gives the best performance results, based on hydrodynamics studies (Rensselaer Polytechnic Institute / T. Wei) and tests made in C.F.D. software (Computational Fluid Dynamics). The dolphin tail-shaped ending provides maximum thrust with the least possible energy consumption.
Our 100% silicone hydrodynamic water rails have been designed in a three-dimensional (3D) CAD environment and are produced in the United Kingdom by a high-end silicone production facility. Trials and studies in C.F.D. software showed that Alchemy water rails detain and drive the water on the blade, without losing their shape, even in the toughest conditions. Even in the limit bend of the blade, the water rail retains its shape, drives the water from the beginning of the stroke, and provides an immediate response to the diver's moves. Compared to rubber, silicone is far superior when it comes to strength and shape maintenance under extreme conditions.
Choosing the correct stiffness & footpockets for your fins can be a cumbersome experience. Here's how to get it right.
Alchemy fins/blades are produced upon order. We do not keep them in stock. Lead time may vary from 5 to 25 working days, depending on workload. The normal lead time is 10 working days. Please be sure to contact us in order to know the waiting time before you place your order.
If you purchase blades with footpockets from our online shop, you will receive a fully assembled pair of fins, ready to use. However, if you only order blades and plan to attach them to footpockets yourself, please keep the following points in mind:
- We only use glue to attach the blades to the footpockets. Please contact us for guidance on how to do it the right way.
- Avoid drilling the blades as it will void the 5-year warranty.
- Let us know the type of footpockets you plan to use as longer or shorter water rails may be necessary.
- Ensure that the end of the footpockets' tendons aligns with the length of the already installed water rails. If footpockets without side tendons or shortened purposely are used, the water rails must be extended accordingly. The side edges of the blades should never be left exposed.
Please reach out to us if you have any further questions or concerns.

Throughout the years, some of the world's deepest freedivers have used
Alchemy fins to set countless World and National records.
Here's what they had to say about us.
The best carbon fiber fins out there. I've been diving for 5 years now - spearfishing, line diving, and underwater photography. I've had the opportunity to try on lots of different fins and alchemy has always been the best. The fins are extremely light, smooth, and look the best in the water! I've put these fins through a lot too, in and out of lots of boats, I've sailed across 2 oceans, once for 80 days, and the fins held up just perfect! I highly recommend the fins and I have no intentions of changing which fins I take out on the water!
Fin was better than my dive R carbons by far.
Outstanding performance and comfort in the water. I also love the simple and clean design. 10/10 for Alchemy blades!
Bonaire is the perfect spot to
kick your Plus.
