Where all the latest news about HANALEI FINS can be found, we tend to put all of our announcements here, as well as information about new designs and the testing process.

Some of the historical blog posts from previous years are slowly being moved into the new blog. Initially, all of the most interesting ones will be moved over. Eventually we hope to get all of the old posts up here so they are accessible.

Most of the new posts also get placed on our Facebook page, so they can be read there as well.

A4C-500BW TWIN v2


Written by: | Posted on: | Category:

We continue to work on the BLENDED-WING update to the A4C-500.

The latest version of the A4C-500BW has some refinements from the first version. We started by moving the bend down slightly further on the fin.

We have also adjusted the shape of the cutaway to make it a little more friendly for cutting FUTURES bases.

Additionally, the foils have been further refined to improve performance.

The original version has been getting a lot of testing, and the consensus now is that these BLENDED-WING versions of the A4C are significantly better than the original design. These have recently been tested on a tow-in session with excellent results.

So we are confident that these design changes will move the A4C series forward. To that end, we will make up samples to send to the factory to implement these changes on all new versions of these templates. The updated A4C series will include the A4C-500 and A4C-550.
