With the arrival of the new surf season, we have a new fin design.
This started as a design for a range of new canard fins for twinzers, so we will discuss the canard first. The name of this new canard series is CNRD.
The version shown here is the CNRD-350. The range consists of four sizes - 3.00", ...
When we first introduced the SP9 fin series, we mentioned that the intended construction methodology involved a combination of G10 and plywood.
This build technique allowed the fin's blade to flex torsionally, which could not be achieved with a solid fiberglass version.
With its solid G10 base and a blade combining G10 and Baltic Birch ...
Things have been a little quiet on the fin front for the last few months as we have been very busy working on the new fin system. But we finally managed to squeeze out a new design that has been around for some time but not as a single fin.
Say aloha to the SP9-750 SINGLE!
This fin takes inspiration from the SP9 ...
After a very long time, we finished another one of our wing fins.
This version had many interruptions, but it is finally done and looks good.
This one is 7.50" tall with more rake and elliptical wings.
We are starting to give these fins a little more rake to increase their versatility. Adding additional rake enhances the ...
The VTX fins have been tested for the entire winter season here in Hawaii. Plus, Lance Carleton has just started testing them in Australia.
They are a very versatile set of quads and take a slightly different approach in that they intentionally have only two options for the larger fins. Coupled with several options for the back fins, depending ...
As we mentioned in the last post, we have been working on a larger version of the front fin, and here it is. The VTX-538 is coupled with the VTX-375B.
This is not the final version of this design. We have made a few minor tweaks to harmonize the various sizes. Notably, the trailing edge of the front fins has now been matched with the leading ...
This is our latest wing center fin. It differs from the others we have done recently as it utilizes an elliptical wing instead of the previous straight wings.
The elliptical wings will generate less lift and be much smoother through the turns. The idea with this design is to get less tail lift due to the reduced wing lift. Also, the shape ...
This is the latest fin design we have been working on for testing this winter. It is another of our split keel designs, but this one differs from any of the current versions.
The driving force behind this design was to develop a quad set that worked in either a tight or a spread-out cluster. Most of our current quads or split-keels are optimized ...
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, ...
Another one of our wing single fins has just been finished. This is another 6.00" version. Almost identical to the first one, just different colors.
The wings on these more recent ones all have the same 5" wing span.
After making a few of these over the last few weeks, we finally settled on how we measure the height. In the ...
H8-400C Center Fin
We already have the side fin version of the H8-400 in production. Here is a center fin version that makes for an incredibly high-performance center fin.
It is only 4.00" in height but has plenty of drive and hold due to its shape and area.
We are contemplating adding this fin to our range of CNC fins but ...
We are going to document the assembly of one of our WNG fins for those that are interested.
There were several steps before this one, but this is the first of the assembly process.
It starts by gluing the tenon and mortise joint together. Next, a custom right-angle jig holds the wing at the right angle.
This initial wing plate ...
It has been some time since we made one of these wing single fins. Something a little different than what we usually post.
These are always interesting as they are a real challenge to make by hand and take much time to foil. Essentially you are foiling three fins in one.
The fin is made from a mast for the main blade, and the wings ...
We are revisiting one of our older fin designs to see how the BLENDED-WING concept works on a more wing-like template.
After foiling up a set, it is evident that this concept belongs on a fin of this style. Everything about it looks right. Usually, fins with this wing style that are pretty upright can be a little twitchy. The feeling is that ...
The next fin design we will test with the BLENDED-WING concept is the largest version of the Q5 series - Q5-600BW.
A little different than the A4C versions, primarily due to the shape of this fin compared to the A4C. It still has similar characteristics in the outline of the profile, but the HOLOFOILS are different.
We ...
As mentioned in the previous post, here is the larger version of the A4C with the bent tip - A4C-550BT.
It has all of the same properties as the smaller version, including the thicknesses for the profile.
For some reason, it looks even better on a larger fin and significantly affects the fin's weight.
It is worth ...
