HANALEI FINS manufactures an extensive range of both RTM molded composite fins (HRD-KORE), as well as custom fiberglass & G-10 fins (HANALEI FINS). The custom fins include quads, thrusters, side bites, and regular single fins.

We offer a range of completely unique templates that are unlike anything else available in the marketplace. All fins are offered with either GEARBOX or DUAL TAB bases, as well as FUTURES bases on some designs. Many of the fin designs feature hollow inside foils for an extra performance boost.

Our custom handmade fins are produced one at a time the old fashioned way, with hand foiling and finishing. These are high quality fins with exceptional foils that feature very unique characteristics. What we call "Fearless Foils"! The single fin range only available in fiberglass.

The HRD-KORE range of fins (WTF, XTC, DS, WS2, A3, XPD2, Q2, H3, H5, and STD) are all molded composite fins, constructed using a combination of carbon fiber, fiberglass, and a SORIC Hex core. This is a light strong construction method that allows us to deliver high quality fins at a reasonable price point. All of these fins are offered with our GEARBOX base, as well as DUAL TAB, and in some templates FUTURES bases.

The various choices will be presented in three groupings - HRD-KORE, CUSTOM, and SINGLE fins.



HRD-KORE is our name for the type of construction method used on our line of molded fins. It is an RTM molding technology that produces accurate, light, and strong fins. Wide range of very unique designs. More on the way!


The range of custom fins includes all of the HRD-KORE ranges, but additionally there are a number of new and unique templates that are currently only available as custom fins. Some of the fins shown are still in the prototyping phase.


Hanalei Fins has an extensive range of very unique and functional single fins. These are all made from solid fiberglass and are available in a wide range of sizes. All of our single fins are custom handmade and finished.



The HANALEI FINS Blog is the best source for the latest info on what we are working on. There are regular posts dealing with new fin designs and the testing of these designs. Our goal to provide as much relevent information as possible about our fins, and what to expect in the future!


Fin Setup is more art than science, but the beauty of an adjustable fin system is that you can go out and experiment for yourself to verify what effect a change in fin placement can have on the overall performance of a board. This primer will use some terminology that is best explained up front so that we are all speaking the same language.


These layout guides provide information on the positioning of fins for various types of fin setups. They are not specific to any given board length as they are only intended to serve as a starting point. It is left to the builder to determine their preferred layout. Downloadable copies are available.
