Specs and Speculations

Posted on May 4th, 2017 in News.


Colourful and sleek designs often have something of a nasty knack for stealing attention before the performance oriented features can be given the time of day. As was the case with NMD and VS‘s latest range of Quad-Concave bodyboards which sold out in little over a month from their release. 

In anticipation to their second run of the Quad-Concave line, we must ask of you (only briefly) to not bathe in appreciation as to their physique, and instead allow us a moment of your time to explain each individual component of these models and what it is exactly about them which has the bodyboarding world hot and bothered.

PFS3 (From then to now)

PFS3, previously known as the Parabolic flex system, is the core of the bodyboard. A new(ish) concept of foam displacement which revolves in it’s entirety around water displacement and flow.

To simplify, and (more importantly) save you from reading all of the above, the first of its kind was the PFS1 as seen above. The curved beams you see down each rail of the board separate two different densities of PP foam. The outside rails are of a 1.6p density whilst the inside is of a 1.9p density. The idea being, the softer structured outer rails flex out and help direct water flow towards the centre of the board. Allowing the rider maximum control from the softened rails and maximum speed from the redirected water flow down the centre of the board.

The PFS2 followed the same concept, however, this time round they ran the same density of PP foam across the entire board. The beams which were initially there to separate the different densities of foam now became more prominent, protruding through the slick looking like something of an extended concave. The idea remained that the water flow should be centred and the outer rails should be easily manipulated to maximise speed. 

The latest and most relevant instalment is of course the new PFS3 system. Available both with Quad-Concave bodyboards and for individual purchase. The PFS3 much like the PFS2 maintained the same density of foam the whole way through, but again became more prominent in terms of water flow.

The latest and greatest: PFS3, plus Quad Concave. 

As seen in the above image the beams which were initially used (PFS1) to separate two different densities of foam are now used to maximise water flow straight down the centre of the board. Running the full length, the new PFS3 beams are entirely straight and emulate the same ideology as previous PFS concepts. Running these beams as a more centred structure not only allows water flow straight down the centre of the board, but also allows riders to ride with a lot more rail. The deeper edge means riders can draw more power than before out of their bottom turns, carves and spins. 


As for the newly introduced Quad Concave. Paralleled with its release we saw a series of convoluted words in explanation as to the physics behind the idea. Leaving even the best of us with clouded interpretations. Now, to put it simply, the inner two concaves’ run within the confines of the already implemented PFS3 system, once again aiding in maximising centred water flow. Additionally, having those extra inner concaves’ allows the rider to draw a higher line and exert more power into the bottom turn.
The outer concaves’ complimented by the PFS3 system draws water down the full length of the rail creating a focused and powerful bottom turn as the water passes the entire length of the board. The Quad Concave in terms of rail to rail surfing is perhaps the most powerful option to ever be ran as a stock board. 


The Wi-Fly tail actually cuts an entire inch off the full length of your extended rail. By cutting the tail back in a diagonal catch you’re cutting the length and effectively cutting any extra need for control. Although only an inch down you’re going to find a huge change in terms of control of the board. Bottom turning, carving and spinning is about to become a whole lot easier with a tail that releases with an inch less of grab.

The new Wi-Fly tail is about to take your control game to another level..

Clearly seen above, the diagonal cut which connects downwards to the tail makes for a smaller spaced crescent tail. Now, it hasn’t been noted anywhere, but, you can see in the above image where and how the tail connects with the PFS3 system. All the boards water flow comes gushing straight down the centre of the board and displaces right through the the newly introduced tail. You do the Math, smaller release point, higher pressure.

Although Dave Winchester can hardly be classified as an every day bodyboarder, the man can be seen putting the new tech to use here,
