Alkali Fins

Color Grey/White

Twin fins are now a common weapon in most surfers arsenal. No longer just a novelty for small waves, shapers like Simon Jones (Morning of the Earth Surfboards) have proven you can build progressive equipment for all types of waves and utilise the speed and flow of two fins underfoot. T

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

The large template has enough rake and tip area to hold through turns but releases smoothly to maintain speed at all times. T

his fin template is a trusted favourite worldwide. Designed to suit a wide range of craft, from channelled twin pins, wide tail fish, and even small wave performance craft.

For a little more hold, a rear stabiliser would also fit nicely with this set.
