Surf School Logo by Adam Primmer
Maybe something like this or that involves paddle boards instead of surf boards with a really wavy type yet neat.
The symbol is inspired by the view of the riders when they're in the barrell.
Minimal black and white logo by amio. This circular design uses negative space fin to evoke both a shark fin and a surf wave.
