Doppelgänger Twin

Designed for surfers looking for a fast, flowing twin setup that sits between a classic keel and a modern performance twin.

The Doppelgänger Twin blends the drive and hold of a traditional keel with the responsiveness of a more upright performance twin. The template combines an upright leading edge for tighter directional changes with a drawn semi-keel trailing edge that maintains speed and control through longer arcs.

The 80/20 foil creates efficient water flow and lift, helping the fin carry speed through flatter sections while maintaining predictable hold through committed rail turns. The slightly flatter inside face keeps the fin stable under pressure, while the foiled outer face adds sensitivity and drive.

Best suited for:

• Performance fish
• Hybrid twin shapes
• Wider swallow tails
• Open-face surfing and drawn-out lines
