In MB fins, the major factor that increases performance is the new dedicated “Reverse Parabolic” lamination; a parabolic curvature which, instead of having the part with greater flexion at the top, it is near the foot. A complete reversal of concepts and an evolution of what our DPC (Double Parabolic Curve) blades had. This dedicated lamination significantly changes the mechanical behavior of the fin. The surface that generates the thrust is in fact greater than the surface that generates hydrodynamic resistance, thus producing greater elastic deformations and greater propulsion. There is such a big advantage that it is possible to use stiffer blades, therefore with greater performance, but using the same effort normally used with lighter blades. MB fins feature new rounded section water rails that improve water containment on the blade and reduce water vortexes on the outer sides. The MB feature a greater thrust surface and, for this reason, the water rails are integral, from the foot pocket to the tip of the blades.
