The Matt DAEmon Born Identities Single Tab Fin Set is for surfboards using the Futures Fin system.
These are high-volume, airfoil-based fins. The MDBIs use an airfoil developed at MIT for a human-powered flight project. These are also heavily vectored like the DFeaters, but the concave in these fins has a more modest flow which makes tons of drive without sacrificing as much dynamic control. These fins also have a design enhancement I learned from one Maestro of fin making, Rich Sanders (Inter Ocean Surfboards, Halcyon Fins). The twist lends speed to your maneuvers and allows for more Gs through the end stages of a turn.
Expect lots of speed, glide and dynamic abilty.
StormFins are the moniker I'm using for this project I'm now years deep in. These fins are all high volume, which translates to high lift. Surfing is analagous to flight. These fins are analagous to wings.
These are 3D printed fins made with PETG filament. Improvements are coming, you'll be able to order injection-molded and G10 versions of my fin designs soon - but I still have to make the kickstarter for that.
Thanks for your support!
