Finmas uses higher volume, new foils and better angles of attack to give you fins that create more speed, acceleration, control and agility. If your surfboard choices were similar to the fins you get to pick from, they'd all be 2" thick and the only bottom concaves you could pick from would be flat, or light single concave. The fins you see here on this website are a first generation of designs that work with higher volumes, new airfoils, and even more toe and cant.
Finmas is also an example of a high quality surf product that can be 3D printed. Not only do these fins do more for your surfing, these fins also represent a first example of something that can provide better access to surfing for people in developing world areas.
In developing world areas, surfboards can be relatively easy to obtain. Once you have a surfboard, you can surf but you're going to hope your fins never break. Fins are not easy to come by, and in any place they are available, they're expensive.
Finmas fins are thicker than standard fins.
• More fin volume creates more lift.
• Fins use lift for speed, traction and flow.
• Up to 3x thicker than standard fins.
Finmas uses new foils:
• The Megas use concave to create tons of drive.
• The Kaijans let you drift while setting big, carving lines.
• The Daemons have concave and twist, for drive and hooking turns.
