Surfboard fin manufacturers and sellers are often considered to be out of touch with the science behind their products.“It’s more, ‘this pro surfs with this fin, so we’re putting this in the shop’” said Marc in het Panhuis, a veteran surfer and professor of materials science who leads a team at the University of Wollongong in Australia that makes customized 3-D printed surfboard fins. To help make surfboard design more scientific, the Cranfield University research team aimed to highlight how fluid dynamics can be used to model a peak performance fin.Although a perfect one-size-fits-all fin doesn’t exist, surfers look for fins that help them both accelerate and maneuver easily through the water.

This opens up a new design methodology, where the performances of the different. lift to support the surfboard plus th e surfer, surfboards need to reach a certain speed. The accelerationThe lower pressure differential on Flat and Tow foils still generates lift, but creates more stability. V2 foils in pumping surf can be a little too skatey and unpredictable. Conversely, tow foils in small surf can feel like there’s less turning force and makes it harder to spring out of turns.
