The Wonder Twin is a round wing pin version of the Twin 82. A custom performance twin fin groveler designed for surfers who want to push hard through small waves without holding back.

The shape features a flat deck, a beak nose, and a wide point set above center for paddle power and easy wave entry. The wing pin tail tightens up the back end of the board for control and bite, while the bottom contour runs a double barrel concave from tip to tail for speed and drive.

What makes the Wonder Twin different is in the channels. Doc added a channel running inside each fin, about a quarter of the way up from the tail, plus a short slot channel running from behind the fins out through the tail. Designed to give you the hold of a stabilizer center fin without the drag of an actual third fin. The feedback from riders has been overwhelmingly positive: it locks in like a thruster but flies like a twin.

If you're looking for a performance twin or groveler that lets you push through your turns instead of pulling back, the Wonder Twin is it.
