Introduction

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 center 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 center fin range only available in fiberglass.

The HRD-KORE range of fins (A3, XPD2, QS, 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 CENTER fins.

HRD-KORE Fins

This section will introduce all of the HRD-KORE fins we manufacture, grouped by template family. HRD-KORE is our name for the type of construction method we use on these fins. It is a RTM molding technology that produces accurate, light, and strong fins. For more information see the technical section below.

A3 Range

The A3 range represents one of our more conventional templates, all featuring a small cutaway at the bottom of the trailing edge. These fins feature good turning ability, lots of drive, and tons of speed.

All of the A3 templates feature our custom hollow foil technology on the inner face, which makes for a faster and more responsive fin!

These are very versatile and reliable fins that feature great performance.

H3 & H5 Ranges

The H3-S and H5-S templates are commonly combined with other templates to create quad setups. But these templates can be used by themselves, as needed. The H5-S is the latest generation of this Hammer design. It is used in combo with the A3-L, XPD2-L, and Q2-L to create even more powerful quad sets.

The H3 and H5-S templates are our more unusual shapes, but these really an amazing fins. They combine a very narrow base with a very large tip to generate a lot of flex that really pops out of the turns. Strictly designed to be used as a back fin in quad combos, they also makes excellent side bites in 2+1 setups, as long as there is no kelp in the area where it is being surfed!

The H3-S has a flat inner face, while the H5-S features our unique hollow foil on the inner face. The H5 has slightly more area than the H3 with a little less rake. The latest generation.

STD Range

The STD range of fins is geared towards a more conservative style fin than some of our other offerings. But these are still high performance fins that feature our hollow foil technology on the inside faces of the larger fins. These fins are derived from one of our oldest and well tested fin templates that has been optimized for todays high performance surfboards.

They feature a good balance between base width, rake, and tip area to deliver outstanding all around performance. Another unique aspect of these fins is that they feature a hand polished finish, something not commonly found in the fin market, they have to be seen to believed!

All of the fins in this range are constructed using our HRD-KORE construction method. All of the fins are only available in a SMOKE TINT,.

NRG Range

The NRG range is one of the latest designs that we have been working on. It represents a broad range of designs, including a small trailer fin.

The primary goal behind this design is a fin with a larger tip area for increased drive and holding power. Coupled with a narrow base for increased turning performance. The center (CTR) fin has a slightly shallower blade than the other templates for more looseness.

All of the designs in this range feature strong hollow foils on the inside faces. Additionally, these inner foils are spiraled for better water ejection.

Eventually this design will make it into production utilizing our HRD-KORE construction. For now these are only available as custom fins.

Center Fins

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

Standard Series - STD

This is our latest center fin design, that takes its cue from many of the traditional longboards fins. Although this template was largely derived from one of our older side fin designs.

Feature a wider base for more projection and better tracking for those who are more interested in smooth lines than tight turns!

Has some characteristics from our GS range and then some inspiration from our NS side fin designs. Features a very distinct tip to provide a little more feel to the fin. It fills a hole in our range for people looking for a fin with more projection and drive at the expense of tight turns. Turning can be improved by placing this fin further forward on the board. Due to the increased base area in these fins we recommend selecting a smaller fin if high performance and speed are critical as the smaller fin will have less wetted surface and hence be faster! These fins feature a nice tip flex that will provide a little extra pop out of the turns!

STD Fin Outlines

Currently the fins range in size from 7.00" to 9.50" in 1/2" increments.

Available in RED or SMOKE TINT only! All center fins ship with VersaScrew and hex key!

Ell Series - LS

This is one of our newer center fin design, it is loosely derived from the new LS side bite design that is used in some of our quad setups. Carries forward many of the design elements of our Thumb and Hammer series of fins with the same distinctive tip area, placed on top of a fairly narrow mid-section.

This combination provides maneuverability, projection, and speed. This fin has a lot of properties similar to the Hammer series of fins but without the kelp catching bulb at the leading edge and slightly less area. The leading edge of the fin has a slight reverse curve that provides a better angle of attack for the water as it gets closer to the tip of the fin where most of the area is located. The large amount of area in the top half of the fin and the fact that it is significantly raked allows this fin to be positioned very far forward without sacrificing holding power.

Due to the large tip area combined with the narrower throat, this fin generates a lot of flex that allows it to create a lot of drive out of turns. As with many of our designs the base of the fin has been kept very narrow in order to enhance the turning ability. Unlike the T2 series of fins the area of this design was kept down to a minimum in order to reduce drag and improve speed, this design is all about efficiency! The big design difference is the profile of the leading edge. By utilizing a reverse curve that increases in steepness as it gets closer to the tip, a much better angle of attack is provided for the water flow. This design can be ridden relatively small as the area of the fin is placed where it is most effective. Use this fin with any of our side bite fins in a 2+1 setup for a real performance boost. Or use it as a single fin for lots of drive and speed!

LS Fin Outlines

Currently the fins range in size from 5.00" to 8.50" in 1/2" increments.

Available in RED TINT only! All center fins ship with VersaScrew and hex key!

Thumb 2 Series - T2

This is the second generation of the thumb series of fins, we have built on the excellent features of the original and come up with a new design that brings increased performance to the series. One of the big changes was to add a much more distinct tip on the trailing edge of the fin, this was added to improve the feel of the fin.

The original series had the distinction of feeling like there were no fins in the board, so we tried to go in the other direction with this series. By adding more feel to the fin the surfer could exert better control. The other big change is that more area was added to the fin both in the tip and through the throat and base. This additional area increases the drive of the fin making it more powerful. There is also slightly more rake in the fin allowing it to be placed further forward on the board improving the turning ability. All of these changes allow this fin to be ridden smaller than the original series, typically the fin can be at least one size smaller without sacrificing drive!

The other key feature that has been retained from the original design is a lot of flex in the tip of the fin. This new design flexes slightly less, then the original, but there is still enough to add significant pop out of the turns. These fins have turned out to be popular with SUP surfers as they have a lot of holding power due to the increased tip area.

T2 Fin Outlines

Currently the fins range in size from 5.00" to 9.00" in 1/2" increments.

Available in RED TINT only! All center fins ship with VersaScrew and hex key!

Hammer 3 Series - H3

This is third generation of the Hammer series, it has undergone a lot of refinement to make it more compatible as a rear fin in various quad setups. It adds some of the refinements made to the T2 series. Like the T2 one of the big changes was to add a much more distinct tip at the top of the trailing edge of the fin, this was added to improve the feel of the fin.

By adding more feel to the fin the surfer can exert better control over the board and the direction. The tip area has also been enhanced by increasing the area in the tip and the amount of rake. Additionally, area has also been added through the throat area and in the base to increase drive. This design still retains the leading edge bulb of the original series but the shape has been made a little more subtle and the lower portion of the leading edge now has a straighter line. The bulb still plays a crucial role in the ability of this fin to act like a rudder, essentially as the fin flexes the bulb moves out into the water flow increasing the amount of toe-in and increasing the water flow over the outside face and turning like a rudder, allowing the board to turn tighter!

This fin design has to be experienced in order to appreciate just how well it works. As a center fin it works really well with the T2 side bites. As with the T2 design this fin can be ridden one size smaller than the original design due to the increased area. NOTE: not recommended for any area where there is kelp!

H3 Fin Outlines

Currently the fins range in size from 5.00" to 8.50" in 1/2" increments.

Available in RED TINT only! All center fins ship with VersaScrew and hex key!

Gun Series - GS

The Gun series of fins were original developed for use on large single fin balsa guns, but we soon discovered that it also makes for an excellent longboard fin especially in the smaller sizes. The design took some of our general philosophies and brought them to a longboard/gun fin.

The primary idea being to maintain a fairly narrow base coupled with a lot of rake to enhance the turning ability by allowing the fin to be placed further up on the board. This series started out primarily as a glass-on fin but over time we also started making them as removable fins, especially once they became popular for use on longboards. These fins have been used on guns as large as 12' 6" with great success, they have proven to be very efficient and rock solid.

While these fins were initially designed for guns, over time we have created smaller versions that have turned out to be great center fins on short single fin boards or 2+1 longboards. A good choice for anyone that is intimidated by the more extreme shapes of our other designs! A good all around versatile fin that is very clean!

GS Fin Outlines

Currently the fins range in size from 7.00" to 10.00" in 1/2" increments.

Available in RED TINT only! All center fins ship with VersaScrew and hex key!

Thumb Series - TS

The thumb series of fins is one of our original designs and was first created in the early 70's and has been revised and improved on ever since. This design is extremely versatile and has the distinction of providing a feeling of no fin in the board while still getting great projection and a lot of thrust out of the turns!

The original design concept for this series of fins was to create a fin with a very narrow base, with more area pushed into the tip, and increased rake, coupled with a lot of flex. The narrow base allows the fin to pivot very easily, while the increased rake allows the fin to be placed further forward on the board again enhancing the turning ability. Moving area out into the tip of the fin allows the area of the fin to be reduced to eliminate drag.

These fins have a very smooth feel in the water, and due to the soft outline it often feels as if there are no fins in the board. The heavy flex delivered by these fins, gives them a lot of extra drive out of turns. We have been producing these fins for a long time and they are very popular with longboard surfers that like to nose ride as they really handle well on the face of the wave.

TS Fin Outlines

Currently the fins range in size from 5.00" to 10.00" in 1/2" increments.

Available in RED TINT only! All center fins ship with VersaScrew and hex key!

Technical

This section will describe the various technologies and materials employed in the manufacturing of our fins.

Foils

Foils obviously play a crucial role in the design of a fin and can dramatically impact the performance. Most of our foils are loosely based around the NACA 00 series of wing sections that are ideal for fins.

Foil Shape
Regular Foils

We pay careful attention to the foils used on all our fins. We try to match the best foil for the characteristics of the fin and wherever possible we try to keep the regular foils nice and thick for maximum efficiency.

Hollow Foils

HANALEI FINS are unique in that we have perfected the use of inner hollow foils on the inside faces of most of our fins. We use these foils to increase performance and efficiency. In many cases we also couple these foils with twists and turns in the trailing edge of the fin to better manage the ejection of water from the foils. These foils have a dramatic impact on the overall performance of our fins, but in particular to the speed!

Bases

There are a lot of different fins systems available in the market, many with their own unique style of base. HANALEI FINS only supports the three primary bases - GEARBOX (our base is also compatible with ProBox), DUAL TAB, and FUTURES.

GEARBOX

The GEARBOX base is used in our own fin system GEARBOX, it features a full base for a solid feel and greater strength. The GEARBOX base also features vee notches where the screws land that allow the fin base to be forced down into the box when tightened, creating a compression fit.

The GEARBOX base is also compatible with the ProBox Fin System.

GEARBOX Base
DUAL TAB

The DUAL TAB base is widely available due to the large number of boards with the twin plugs installed. The DUAL TAB base also fits in the GEARBOX fin box. These bases are designed to break under load and therefore tend not to be very durable, breaking at inopportune times. the other problem with these bases is the tendency to flex in the base instead of the fin, this is due to the narrow interface between the fin base and the box.

DUAL TAB Base
FUTURES

The FUTURES fin base is a lot longer than other bases due to the design of their box. Due to the nature of the fin ox design the cant angle is built into the base of the fins instead of into the box. This makes it really complicated making fins for this system, especially if they are custom fins as the can angle has to bee machined into the base of the fin. Fit is critical for these bases as there is no means to tighten them if they are loose.

These bases can also be a lot heaver due to the fact that they are almost double the length of a GEARBOX or DUAL TAB base. This is why you will commonly see these bases heavily machined in order to lighten them up.

FUTURES Bases

RTM Molding

RTM molding is one of the most predominant methods for molding fins. It stands for Resin Transfer Molding. The fabrics and core that make up the fin are laid dry into a mold. The mold is then closed and a vacuum is used to draw resin through the mold, wetting out the materials in the process. The use of a vacuum also draws all the air out of the laminate eliminating air bubbles.

RTM molding is a lot more cost effective and less wasteful than the standard method of foiling a fin out of a solid panel of fiberglass. Because a mold is used it also makes it easier to manufacture more complex shapes in a consistent manner.

Materials

Fins can be made out of a wide range of materials, but these are some common standard materials, with fiberglass being the most prominent one. RTM molded composite fins use a combination of these materials.

Fiberglass

Fiberglass forms the bulk of a fin construction and is applied either side of the core material in our HRD-KORE construction method. The typical fin can have as many as 27 layers of fiberglass to provide strength and some flex.

Custom fins are made out of panels that are built into solid sheets of fiberglass and resin. The number of layers can vary from 30 to 40 layers. This is the standard material for hand foiled fins.

Fiberglass Material
Carbon Fiber

Carbon fiber is very strong and stiff for its weight making it perfect for base stiffening. Employed in the base area of the fin to add stiffness and strength, it is applied to both sides of the fin as an outside layer that is visible in the finished product.

Carbon Fiber Material
SORIC®

Soric® is a conformable flow media for resin infusion. This product features unique hexagonal flow channels across a carrier sheet that create a steady, even resin front. Forms the core for the fin and reduces weight by reducing the layers of fiberglass needed to construct the fin.

SORIC Material
G-10

G-10 glass cloth reinforced epoxy natural is typically a yellowish to light green color. The most versatile all-around laminate grades are continuous glass woven fabric impregnated with an epoxy resin binder. These panels are made under high pressure so there is no air in the panel and the resin to fiber ration is very high. This makes for an incredibly strong panel.

Because these panels are manufactured it makes it a lot simpler for a fin manufacturer as one simply purchases the panels and then cuts fins out of it as needed. The panels are a lot more expensive than a standard fiberglass panel, but worth it for the strength.

G-10 Material
