CUSTOM Fins
HANDMADE
CUSTOM Fin Range
Our CUSTOM range of fins is broken up into a number of different distinct design series, much like the CNC or HRD-KORE ranges.
Each of these series will be detailed separately with information presented on the available templates, dimensional information, and combinations. Due to the number of fins sizes and the various base choices, the purchasing info is presented differently than for the CNC and HRD-KORE ranges.
The various choices are grouped under the type of bases required for the fins. Within each base choice there is a SIZE dropdown allow the height of the fin to be selected from the available choice. Then there is a COLOR dropdown for selecting the appropriate color from the available choices. Based on the choices made the price for the fin will be reflected in the BUY NOW button.
All FUTURES base choices will add an additional US$15.00 per fin for the base to the overall price.
Clicking on one of the cards below will take you to the section of the page for those fins. All fins can now be ordered directly from this page. It is no longer necessary to navigate to the store to order custom fins!

The A4C series has undergone extensive testing before being put into production. This testing process resulted in a lot of refinements and improvements to the series easily making them the most versatile fins in our CNC and HRD-KORE range.
This series also has the widest range of sizes. These sizes cover a wide spectrum of fin combos from twinzers to thrusters. We'll provide more details on the different possible combinations below.
The design of the A4C is a combination of our original A3 and XPD2 designs, the idea was to combine the best characteristics of the two into a fresh design that would eventually serve as a replacement for these older designs. In order to make this series as versatile as possible, we added a number of different sizes.
The shape of this series features a strong cutaway at the base and a reverse curve in the upper portion of the tip, adding more tip area. The trailing edge of the fin is shaped like an "S" in profile to better control the water flow off the trailing edge of the fin. In this aspect it is very similar to the XPD2, just all of these features have been enhanced. When coupled with the PHAT FOILS it further enhances the water flow on and off the fin.
The consensus is that these fins are total winners for the general consumer as they are easy to get your head around and don’t have a lot of visually unusual shapes. Of course, once you start looking closer there is clearly a lot more going on than your typical dolphin fin, but due to the more conventional shape, they are much more approachable for the average surfer. This is a good thing in our minds as it will attract more people to trying something different, and once they do they will be blown away.
The versatility of this series has also been enhanced by the addition of the A4C-500CK KAHI center fin, these center fins are a game-changer in a thruster setup as they allow a thruster to feel and behave a lot more like a quad. They allow speed to be maintained through turns and add looseness without loss of holding power!
All of the fins in this new series feature both our PHAT FOILS and HOLOFOILS and are available with GEARBOX, DUAL TAB, and FUTURES bases.
Custom versions of these fins are also available along with some additional sizes. The custom versions are also offered with optional KAHI cutaways, which are not available in the HRD-KORE side fins.
NOTE: we should also point out that the custom fins offer an option to upgrade to the v6 template that uses a cutaway shape that was pioneered on the Q5 and has proved extremely beneficial on the A4C. So the fin images shown on this page will use that template as we feel it is the best choice in a custom version.
A4C CUSTOM Series


The A4C CUSTOM series offers a number of sizes that have not yet been made available in the production versions. Plus these v6 versions of the design feature a revised cutaway design based on the one used in the Q5 series.
The small change to the cutaway actually made a difference to the performance of the fin, but one of the main motives for this design is to allow the cutaway to be more faithfully reproduced on FUTURES bases.
The following sizes are available - 4.00", 4.25", 4.50", 4.75", 5.00", 5.25", 5.50", and 6.00"

The latest generation of the Q family of fin designs - Q5!
We have been working on this design for over a year now and completed the final testing this winter. They represent the next advancement in the Q series of fins, with a designs that is functional and versatile.
The Q5 still carries forward the elliptical outline of previous versions of the series, but features a more upright stance and refined blade tip. The shape of the cutaway has been refined to be more effective and to enhance its functionality on FUTURES bases. The cutaway keeps the base narrow for tight turns and maneuverability.
As with previous versions it still carries a HOLOFOIL on the inside face but on this design it is a little more extreme, improving speed and overall performance.
This series is all about smooth power and versatility!
There are a wide range of templates making up this series in order to provide the most effective combos. These range from twinzer style setups all the way through to twinnies!
While currently only available as custom made fins this series will be the next to go to production as CNC machined fins. They will significantly enhance our CNC range.

The latest generation of our family of keel designs - K9! This is the fin that is also used in the K9/PWR combo. It takes our original KCS keel fin and updates it with a number of improvements.
The overall base length has been shortened to reducing tracking, but the most significant change is the introduction of the KAHI (cutaway). This is a fairly extreme cutaway that really helps loosen up the design while still leaving the fin with plenty of drive. By reducing the base length and adding the KAHI we are reducing drag making the fin faster.
As with most of our new designs these fins have PHAT FOILS and HOLOFOILS on the inside faces. The trailing edge of the fin is also cambered to help focus the water flow through the center of the fin.
These fins work very well and are an excellent choice for a twin fin, in the larger sizes, also fishes where they can be combined with the PWR fin for an even more powerful setup.
K9 CUSTOM Fins


Currently, the K9 series is only made in three sizes, all with KAHI's. As shown in the K9/PWR combo the middle size is used in that combo.
The larger version is used for twin fins and fishes, and the smallest version is best suited for a smaller combo with the PWR back fin or possibly as a side fin in a thruster setup. It could also be combined with a different template in a quad setup.

WARNING - DUAL TAB Fin Bases
HANALEI FINS cannot guarantee against the breakage of dual tab bases. The DUAL TAB system is designed to break under a certain load or hard impact. We try to make the tabs as strong as possible but there is only so much we can do before we run into the limitations of the base design.
If a DUAL TAB base does break we will work with the customer to replace the fins at a reduced price, but we cannot outright replace the fins with no charge!
NOTE - REPLACEMENT Fins
HANALEI FINS cannot sell individual side fins, should you lose a side fin, as it means we have to break up a set of fins and then we are left with a fin that we have little chance of selling by itself.
If a fin is lost we will work with the customer by selling a set of replacement fins at a reduced price, these replacement fins would not be in a bag in order to keep the cost down!
INFO - FLIP TIP Fins
For anyone interested in our fins featuring FLIP TIPS, please be aware that these fins are sensitive to the amount of toe-in used in the box setup, so it is worth checking with us.
We have run into a number of cases where fin boxes setup with an excessive amount of toe-in, have caused issues with fins featuring FLIP TIPS. We want to ensure there are no problems with our fins, therefore we are offering to verify that they will work in the setup on any given board, before buying any of these fins.
Before you order any of these fins, if you are unsure about whether they will work in your board, please CONTACT us so we can make sure they will work for you!
