The Cali Twin collaboration between myself and Matt Biolos. It's a modern, single to double concave, twin + trailer based on my most popular modern shortboard; The SuperTwin.

"Mark allowed me the honour of tweaking his iconic Super Twin model to create a modern, user-friendly, small wave weapon. We dramatically lowered the entry rocker, widened the nose and tail block, and added a couple of inches of width to the overall outline, giving gobs of glide in gutless surf.

We flattened the deck for stability but retained MR's classic speedy, down soft rails and his modern performance tail rocker‚ ensuring it still turns proper and precise. Flat where it needs to be, but still curvy in the right spots, and skates along but still turns in tight spots. This is a Fish that you can grovel the small stuff, but still really rip on". - Matt Biolos


Standard fin setup is twin fin plus stabiliser.

*Spray not included. To add a spray, please select from the sprays offered below.

  • Outline: Wider nose and tail, with extra width through the centre
  • Rocker: Lower entry rocker
  • Concave: 
  • Rails: Medium to full rails
  • Deck: Flatter deck for extra stability
