The only brand I will buy.
The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.
Quad Rears designed to work with both medium & large H4 sets.
This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets.
While the science behind the template, materials & the foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.

H4 quads enhanced the performance of my 7'6" HI Mid6. It is now faster with positive projections out of the bottom turn and speed gains on cut backs. They are well worth the extra $$.
The instant off the line speed, quick maneuverability, and drive down the line make this the perfect SUP fin set. Tri fin for slower point breaks when you want fast hits off the lip and stay in the pocket. Quad set for beach breaks and dropping in outside sand bars, the added speed and drive allow you to link up sections and get around crumbling sections with ease. Bottom turns never felt so good. The H4’s have definitely upped my wave game. You know you’re onto something when all the shortboarders sitting inside give you shakas hoots and hollas, when you finish a big set wave.
I’ve tried lots of quads and these are the best ones. I totally recommend them.
I had a H4 thruster set for a while in my 5’11 CI OG Flyer. Bought the H4 quad rears to try in my grovelling board (5’7 CI Ultra Joe) which works better as a quad and usually has AM template fins in it. Using the H4 quad set gives a bit more speed, pushes back a bit harder on a bottom turn and the board definitely holds higher in the wave face. In slow sloppy waves you wouldn’t notice much difference, the AM fins are excellent in that board, but in quick steep waves especially over a couple of feet it is obvious after your first turn.
