Flex fins have been used in board surfing for quite some time. The concept of using a fin with just enough flex on a surf kayak was the project Vince Shay has been working on for quite some time.

The idea is for the fin to flex enough to create tension when going into a turn and then releasing or unwinding its energy when coming out of the turn, thereby accelerating the kayak.

The fins will be available in sizes ranging from 2.5”- 4.5”, with 0 and 8 degree cant.

A big thanks to Vince Shay for seeing the project through, Demany Smith, who got everyone together and Rainbow Fin Company, for making a great product.
