Dude, it’s been a radical evolution. We went from heavy, single-fin “logs” focused on straight-line trim to short, light, multi-fin rockets. The 70s shortboard revolution was the game-changer—shorter lengths, sharper rails, and lighter materials allowed for insane vertical turns and tube-riding. Modern designs are hyper-specialized: from groveler wide-tails for small waves to high-performance shortboards and tow-in guns for Jaws. It’s all about matching the plank to the wave and your style, allowing way more radical, critical surfing than the old mals ever could.
