Alchemy S 30 Snowboard - Red Logo/White Water Rails - Perfect for Freestyle & All-Mountain Riding

Meet our ground-breaking carbon fins that are progressive in every way. With top notch performance and configurability, they are designed to enable a wide range of spearos push the boundaries of what is possible. Every aspect of the Alchemy S30 is designed in pursuit of greatness. Based on a completely new blueprint which aims to help spearos outperform themselves even in the most extreme scenarios, they are engineered to go full force, all the time. S for Speed, S for Safety, S for Spearfishing.

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 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.

S-30 feature the ultimate carbon layer positioning within each blade. Eleven (11) 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.

S-30 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.

S-30 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.
