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.
