H8 Fin Combinations

There are no specific combos for the H8, as it is generally used with other fin series as a back fin in a quad setup.


This is the 8th generation version of this design, which continues to evolve as one of the best choices for an excellent rear fin in a quad setup or as a side bite in a 2PLUS1 setup.

These fins have effortless turning abilities while providing lots of drive and hold for such a small fin. This latest version has less area than the previous iteration to better balance performance. The throat has a shape that is better at generating lift to help with performance. While the upper blade is now more fully foiled and carries the foil vertically across the entire blade.

They can be combined with most of our large quad front fins to add a whole new dimension to a quad setup. They are also popular as side bites in 2PLUS1 configurations.

Due to the shape and rake of the upper blade, these fins provide a lot of drive out of a turn as the edge will engage late into the turn. The Hammer design has been part of our range for a very long time and continues to evolve, and this version is the most current production version. We feel this version has brought this design to a point where it is now well-balanced in capabilities and can be utilized in various conditions.


We are now looking at doing a Centre fin in the H8 due to customer requests - coming soon
