Fivenine – by Fourth Surfboards is a high performance board which works in smaller waves or a performance all-rounder for the average surfer. This model is the go to groveler board for the Fourth team by being shorter and wider to excel in everyday conditions. The outline is basically a squashed down bullet shape shortboard, this accentuates the pivot point of the tail hip and the parallel forward point past the fins, which gives you a stable platform and down the line speed off the tail. Then the nose’s gradual curve offers the balance between stability and control without getting in the way through critical turns.

The flatter tail rocker engages plenty of board in the water adding to that forward drive and a higher nose rocker complements the outline nose template. The foil is slightly thicker more forward to again offer support and stability at lower speeds and the deeper concaves give you instant lift and bite through the tail when leaning on the 60/40 boxy short board rails.

All in all, this board will offer everything you want in small waves in order to get bigger and faster turns in the bag and more boost when looking for airs. If you want an easy to use shortboard that helps with day to day surfing struggles, such as bad waves and inconsistent technique due to not surfing enough, then this is the option for you.

FLEXLITE Construction

The Flex-Lite construction ticks all the boxes from strength, flex, control, feel, weight and most importantly, versatility. When it comes to understanding flow, drive, control and speed, Fourth looked at flex patterns and torque levels at different speeds. The aim was to ensure that you can load up and release energy through turns using the curves of your surfboard that will keep your rails engaged with the face of the wave. The versatility of the Flexlite construction is unrivalled in performance.


The core of the blank is super-fused EPS, which has two high density polyester flex controllers running through it. These act as integral dampeners when powering through turns, adding control, and taking away some of the natural float of an out-and-out EPS core board.The flex controllers are angled from tail to nose, at the same tow as the side fins. This loads the torque directly towards your fins through turns, meaning at lower speeds, your projection will carry you with effortless glide, and at higher speeds, you can load up and accelerate out.


When the board is laminated it happens in a heat controlled environment using ‘resin research’ epoxy resin.

‘Resin research’ epoxy is ground breaking stuff, not only is it over 40% bio content it is also the strongest, lightest and brightest epoxy on the market. It isn’t just safer to use and better for the environment, it is also the best performing resin we could get our hands on. Given the characteristics of the foam and the resin, this surfboard as a product uses less resin per foot than standard construction surfboards, meaning the weight is further reduced. It all plays a part in why this construction method is so special.


Hexel S-glass fibre glass is used to laminate the board along with the epoxy resin. S-glass is pound for pound the strongest woven 4oz cloth available on the market. Offering up to 4x more tensile strength than other available cloths on the market. As standard we apply two layers of s-glass to each side of the board. The strength to weight ratio really is amazing – All the while gaining flex recoil instead of having a stiff, non flexing, pop out feel like some EPS epoxy sandwich construction surfboards have.

Finally the board is heated in a hot box over night at 35 degrees, this ensures curing times are sped up during the first 72 hours of the board’s life. Heat is a really important factor when using epoxy resins, the right temperatures must be maintained in order to exploit the epoxies characteristics.


Once the board has been in the hot box, we apply a 100% sand finish to the board which we believe is the strongest and lightest method to finish a surfboard. This finishing process is standard on all of our boards and is a testament to our factory staff that they can use this finish on our epoxy boards as well. Flatter sanding, sharper edges and resin gloss give these boards the Ferrari finish they deserve.

*Usually denotes a minor blemish or construction error which has been repaired to a “as good as new” standard of finish and often comes with a unique spray or colour variation.
