With a nod to the great Mark Richards, the Classic Twin is fast and loose, offering all the dynamics of an authentic twin fin experience. 

This template is a trusted favourite worldwide, and has enough rake and tip area to hold through turns but releases smoothly to maintain speed at all times. 

Tube riding is another place where twins will shine - shooting through barrels freely without the friction of a third fin.

There is something special about owning a surfboard with glass-on fins. They feel solid and engaged underfoot, plus they look fantastic and earn respect from core lords. Our glass-on fins are based on our best selling templates. We give them a rough sand finish which will provide a solid bond to your board. The laminator will thank you.

The team at Alkali Fins are proud of our history creating fins for the world's best shapers, and our template library is a history lesson in fin design. And if you've never given it a go before, we encourage everyone to get out in the back shed and make yourself a board. Once your board is shaped, hand the laminator some Alkali Glass-ons, and you're set.
