Enhance the Flow…

It has been some time since we posted an update on the SPLT (now renamed VTX) series that we have been testing for several months.

This has turned out to be an interesting design meeting our expectations. We started with the VTX-500 and the VTX-338 for the initial testing. Over the intervening months, it has ...

We are stoked to announce that we have just received another batch of CNC fins. These include the brand new F8 and H8 series. We now have the remaining sizes for the Q5 series.

All of these fins are now on the website and available for purchase. We are also a couple of weeks away from having ...

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 ...

Finished 5.00" version of the WNG center fin. This one has a GEARBOX base.

We have four more of these wing fins on the go, soon there will be a lot more photos of them.

Finally, the bulked out wing fin blank.

After adding the extra pieces of material to the tips of the wings we are now ready to start creating the wing profile.

This involved tapering the wing blocks ...

Now that the base plate has been added to the mast, we will add the bulking plates.

These bulking plates are used to increase the thickness of the wings to accommodate the upsweep angle and taper.

In ...

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 ...

After the recent work on the FLIPTWO tips, we decided to see where we could take these ideas by exploring similar concepts.

We have taken the A4C-500 and given it what we call a "bent tip," where we create a bend above the center of the height of the fin. This results in several changes to the profile of the fin.

1. Thinner ...

We have added a larger size to the F8 series - the F8-550FT. This fin is intended for any situation where a larger fin is needed or used as a twin fin.

We decided to add a bigger size based on the feedback on the F8-500FT. It is intended to be used primarily as a twin fin. But it could also be coupled with the F8-425FT to ...

We have added a larger size to the XT2 series - the XT2-550. This fin is intended for any situation where a larger fin is needed or used as a twin fin.

Generally, the XT2 fins are low-area designs to maximize speed. This larger version would be the best choice in situations where more drive is desirable.

It is a scaled-up ...
