Hanalei Fins CNC K9/PWR Quad Set | Dual Tab Base

Lets start with the front fins of this Quad set, the K9-450K, our KAHI cutaway keel fin. This fin provides a great combination of drive, manoeuvrability, and speed. The most prominent feature is the extreme cutaway. We call this cutaway style a KAHI. The cutaway keeps the base of the fin very narrow, allowing the board to turn quickly. While the rake and blade still provide plenty of power and projection. This fin serves as the engine for the combo.

It is paired up with the PWR-400 as the back fin. This fin serves a very distinct role. Due to the shape of the fin, the primary purpose is to add extra drive and speed later in a turn. This fin is commonly set up with slightly overlapping inside the front fin. The shape of the fin concentrates the area down low, where it can add extra tracking and drive to a turn. Thereby complementing the front fin.

Both of these fins feature HOLOFOILS that improve their efficiency.

These fins are ideally suited to fish-style boards with a twin-keel setup. They have also proven excellent for kneeboard fish-style boards.
