The current generation of the Hammer fin design. This is the 5th generation version of this design, that continues to evolve as one of the best choice for a positive rear fin in a quad setup.

These fins have effortless turning abilities, while provide lots of drive and hold for such a small fin.

They can be combined with most of our large quad front fins to add a whole new dimension to a quad setup. 

Due to the shape and rake of the upper blade these fins provide a lot of drive out of a turn as the blade will engage late into the turn. The Hammer design has been part of our range for a very long time and continues to evolve, this version is the most current production version.

The H5-400 features our unique HOLOFOILS on the inner face. The H5 has slightly more area than the earlier version with a little less rake. The latest generation now available as a CNC machined fin!
