Cosmic Twin

Joel Fitzgerald's Mid Length Cosmic Twin Fin is about catching imagination. View the first raw clip that ignited interest in the board.




The Cosmic Twin is the answer to the ultimate question of life, the universe and every wave in between. A progressive mid-length twin fin surfboard designed by Joel Fitzgerald with a deep swallow tail and flat bottom into spiral vee through the keels for speed.

Since releasing the Cosmic Twin in 2019, the board has quickly become one of the most popular shapes in Joel Fitzgerald's range. With plenty of paddle power, the Cosmic Twin can double as your keel-fin fish for smaller surf, as well as your mid-length that can handle bigger waves, especially when you need the extra volume and rail-length to draw longer, faster lines.

Surfed and tested in Indonesia and Australia the Cosmic Twin is ready to add another dimension to your surfing.

The free feeling of the water running through the keels on the Cosmic Twin definitely caught my imagination during my last trip to Indo, and it was one of my favourite boards on the trip. A big thanks to all the boys who worked hard to get the foil on the keels, not to mention excellent the glassing, and sanding.

What can I say about the cosmic twin?
For starters it looks beautiful with the triple stringer and rides so amazing.
The board paddles nicely into waves and holds a rail so well on turns.
Pretty sure I have found my one board quiver 😍
Thanks so much to Kye and Joel. Kurt G.
