MB001 Carbon Fins for Freediving and Spearfishing
The MB001 fins are designed by C4 in collaboration with Marco Bonfanti, specifically developed for the needs of freedivers and spearfishers. Made from T700 carbon, they deliver an optimal combination of lightness, elasticity, and mechanical strength.
Reverse Parabolic Lamination Design and Technology
The main feature of the MB001 is the Reverse Parabolic: the parabolic flex curve is positioned close to the foot rather than at the tip, thanks to advanced lamination studies. This increases the thrust surface area in relation to hydrodynamic resistance, improving the mechanical behavior of the blade and significantly increasing propulsion.
The larger thrust surface makes it possible to use stiffer blades while maintaining the same level of effort, optimizing finning efficiency and performance in the water.
Technical Features of the Blade and Water Rails
- Blade size: 806 × 195 mm
- Fin size, size 42/43: 920 × 195 mm
- Material: T700 Carbon
- Available stiffnesses: 20 Super Soft, 25 Soft, 30 Medium
- Black water rails with a rounded profile to reduce turbulence, extending along the full length of the blade to improve water channeling and reduce edge vortices
Foot Pockets and Sizes
The MB001 fins are fitted with 250 foot pockets pre-shaped with a 3° angle, designed to ensure excellent comfort and smooth, direct power transmission.
The model is available in 7 sizes: 36/37, 38/39, 40/41, 41/42, 42/43, 43/44, 44/45, ensuring a precise and secure fit.
Applications
These carbon fins are specifically developed for freediving and spearfishing, offering a perfect balance between stiffness and elasticity for efficient thrust and greater underwater autonomy.
