are made for the 75% from carbon and the 25% S-Glass (aircraft-derived high-strength glass), obtained by hot melt impregnation systems with tetra-functional resin. This exclusive Cetma Composite high-pressure, high-temperature, vacuum technology implies a defect-free component with a constant fiber-to-resin ratio throughout the blade.

 

Through the engineering design it was possible to distribute the stiffness and mass of the blade in such a way as to "tune" the blade in a certain range of natural frequencies close to those of the finning frequency, thus allowing the phenomenon of resonance.

 

Le Prana fins are assembled with S-Wing booties, which have no stringers.

The water rails are constant type and have a height of 10 mm.

 

Available in the following hardnesses: 25 soft - 30 medium.

Available in 4 sizes: 39/40 - 41/42 - 43/44 - 45/46.

Blade dimensions: 667 x 185 mm.
