A new class of surfboard fin, right under our noses.
Storm Fins are a new class of surfboard fins I've been exploring. Seriously, you haven't seen anything like this fins in our world of surfing yet! These fins have the same outlines as normal surfboard fins, but they have much higher volume which creates more lift at slower speeds. This gives you propulsion without having to pump your legs up and down like a jackrabbit.
Before you check out the graph below, read the following crib notes:
• The vertical axis is labeled Drag / Lift
• The horizontal axis is labeled Speed
• The two sets of lines ( Green and Black) show Lift and Drag
• The higher lines represent the higher amount of lift, and slightly higher drag of thicker fins (StormFins)
• The lower lines represent the lack of lift and lack of drag your common Skinny surfboard fin gives you
• Drag slows you down, Lift propels you forward, grabs onto turns, lands tricky airdrops and holds on through chop and difficult sections.
The airfoils I'm using in these fins have been worked on by aeronautics professionals in order to create unique flying characteristics while maintaining reliability because it's no good when airplanes slip and fall. The airfoils you find on most any normal fin are some of the most basic, simple airfoils out there. They're BORING!
I added some pictures above the graph to serve as cheat codes for you just in case you don't like graphs. The monster truck and heavy-lift airplanes represent what happens to your surfboard when you add StormFins to it. The dinky car and WW1 represent the performance characteristics normal fins are adding to your surfboard.
