The Blue FLAP is a traditional blade for bi-fins with convex tips. They use a similar production design (aside from the tip) as the popular RED FALCON. The fin blade angle was increased to 29, overall length is 870mm, and width is 205mm with a constant section water rail. Changes to the lamination process include an ultra strong, light weight and responsive Double Parabolic Curve (DPC). DPC is now a standard on all C4 carbon fins; it provides the most effective fin curvature during a diver's kick cycle for the most efficient propulsion possible. Thanks to the trademark DPC curvature, the 29 degree angle and the increased length, the performance of the Blue Flap is much higher than the previous C4 Flap VGR.
These changes propel the diver through the water with a more hydrodynamic shape by reducing the profile which leads to a considerable reduction of resistance. Thus speed and efficiency is noticeably increased.
The Blue Flap is made of 100% carbon T700 Megaforce with a large checkered fabric pattern. 3 stiffness levels are available: 25/Soft, 30/Medium, 40/Hard. Full 2 year warranty. 870mm x 205mm.
is recommended for divers under 175lbs or surface swimming where a dynamic performance is the aim over sudden movements and overcoming negative buoyancy during rapid movements like spearfishing action
is ideal for Freedivers weighing between 175-200lbs that require a balanced stiffness to compliment their body weight and a mix of shallow, mid-depth, deeper diving to 30 meters (100’).
blades are still softer than the typical Mfg’s stiffest blade and are typically well suited to divers weighing over 200lbs. The ideal application of a stiff blade for divers under the 200lb+ weight level is typically for deep spearfishing past 30 meters. In this environment a fast accelerating fin that generates sudden thrust is preferred to overcome additional negative buoyancy, current, and sudden changes in depth and variable conditions encountered in challenging spearfishing conditions.
