Overview

UNIQUE TEMPLATE

Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.

SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.

CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.

FIN FOILS TEMPLATE: Thicker base with tapered tip optimises flex & regulates the release of energy during rail to rial transitions.
Ideal Conditions

A wide range of conditions, particularly good in critical overhead waves.

H4s hit sections other fins can’t reach

VW Golf or Toyota Yaris? That’s the difference in speed, handling and cost for my H4s compared to my trusty KA Mediums….

I’ve gone back to KA time and time again after dabbling with MF, JW, PC and Neo Glass Performers and JS but these H4 Small are next level Joy of Surfing!

Smooth like a knife through butter, fast and drivey like a turbo under your feet and so easy to turn, you kinda don’t even contemplate your line being disrupted by a wiggle, a rail bog, catch or feeeling your toes crushing your deck as you try to keep up enough pressure!

Get them, they’re worth it.
