Kernel
A compact twin-fin shape for weak surf.
Kernel
Groveller · 5'0 to 6'0
The Kernel is short, wide and flat. It is built to generate and hold speed when the wave does not offer much power.
Small surf with lift
The generous planing surface and deep channel give the board lift and carry. Twin or quad fin setups can be used to tune looseness and hold.
Where it works
Choose the Kernel when you want a small-board feel with more volume and speed than a standard shortboard can offer in weak surf.
- Family
- Groveller
- Size range
- 5'0 to 6'0
- Fin set-up
- Twin or quad. The fins sit further back than on most boards, closer to the rails, which suits the wide outline and encourages a flowing, rail-to-rail style of surfing rather than pivoty snaps off the tail.
- Construction
- PU, EPS or agave blank, glassed with high bio-content epoxy resin.
Outline
Almost parallel rails from nose to tail, unusually wide for the length. The outline stays wide all the way through rather than tapering the way most boards do, maximising the planing surface and keeping the board fast across flat sections.
Rocker
Very low. As flat as it gets with a little flip in the nose. The minimal rocker is the whole point, keeping the board planing fast across flat sections where a higher-rockered board would stall.
Bottom contours
Single concave running the full length of the board. Simple and consistent, feeding speed from entry to exit without interruption and keeping the board fast and planted where other shapes would stall.
Good for
Small surf, speed generation, flat sections, surfers who want a fun alternative to a fish, and anyone who spends most of their time in average to poor conditions and wants to make the most of it.
