Cetma Composites Mantra CWT Competition Carbon Fins
Lab-made Mantra CWT competition carbon fins with Cetma Composites’ groundbreaking Dynamic Resonance System and 100% Prepreg IM7 carbon fiber blades – designed and tested in partnership with freediving world champion Michele Giurgola, whose signature is also featured on blades.
The Mantra CWT competition blades are tuned using Finite Element Software (FEM) to ensure optimal stiffness distribution throughout the blades and ultra hydrodynamic deformation during operation.
The Mantra CWT competition blades include a blade angle of 27 degrees for excellent CWT performance and variable blade rigidity (3-D Design) that increases energy conversion and propulsion efficiency, providing unrivaled power and performance to the freediver. Underwater, blade rails with variable widths provide greater stability and control. Innovative Cetma composites S-Wing foot pockets are included, allowing optimal power transfer from the heel to the blade.
