Fourth Shortstack Surfboard


The mini-mid genre of surfboards has arrived and these designs are the future of surfing. The Shortstack mini-mids D.N.A comes from the rich stock of the B.P family. It delivers all the stability and trim of the BP mid lengths, but in a more manoeuvrable shorter length that accelerates like nothing else we have ever made.

The Fourth Shortstack Surfboard

The concept of the Shortstack design was about focusing on all that is good about mid lengths and getting that to fit in the pocket of the wave. What you end up with is a board that transcends wave quality whilst enabling a wider range of surfers to stay closer to the power source of a wave. We all want stability and speed to be effortless, and we all want a forgiving board that helps us be the best surfers we can be. This design is an embodyment of those aspirations and we are super excited to be sharing it with everyone.

The outline concentrates on the elliptical values and curve balance of the bp family template. Width around the side fins allows for tail pivot, and parallelity through the central part of the outline combined with the curved nose template helps to extend the rail line further than a conventional outline. This setup gives you lots of down the line speed and trim, but still with good pivot off the tail.

The rocker of this board is very pleasing to the eye. A shortboard esq tail kick and a low medium entry and constant curve combine to give you control in the pocket and lots of speed maintenance on rail. This combination is also a key part of what makes this board such a good paddler with a really generous sweet spot.

The foil, again, is consistent with the B.P design D.N.A. with shortboard foils offering sensitivity combined with a flatter deck for stability. The combination generates a really easy balancing board with great mobility in quick reactive bursts.

The rails are shortboard esq 60/40 with some added tuck around the pivot point of the outline. This shortens up the rail to rail transitions and keep the foam-full frame of the Shortstack design as manoeuvrable as possible.

The bottom contours are a flat nose, which gradually forms into a single concave, then into a double spiral through the fins, and finally a flat exit behind the back fin. This set up gives you vee esq, roll, from rail to rail whilst continuously seeking lift and friction free feels on rail. Therer is a hint of bonzer to this bottom shape, but we aren’t centering all the pivot around a central fin and so maintain that new school release we all love the feeling of off the top.

The fin set up is a thruster set up. slightly clustered for a looser feel. I recommend going for your favourite set of thrusters at first and if you are buying new then my suggestion is the MF large in neo carbon. If the waves are small and clean, the mrtx set from fcs2 is also a brilliant option to free this board up a bit.

This design works well with all the constructions we offer, but as a rule we suggest the eps constructions for a faster responding more lively feel, and the pu constructions for a more natural and carving feel. Feel free to contact us if you need help choosing your flex and construction with this board.

The Short Stack is the future. Its our next offering in the BP line which aims to make better, more critical surfing become easier. That starts with effortlessly catching waves and ends in you doing your best surfing a lot more consistently. Join the revolution, you will never regret making surfing easier to enjoy!

Base Construction

Base Construction (a polyurethane blank with polyester resin) is still considered the most versatile and all-round performance specific construction used the world over by touring surf professionals. At Fourth Surfboards only premium materials are used to produce top-quality boards; US Blanks at the core in blue foam and Hexcel Glass for the laminate bonded with Silmar resin for best balance between weight, performance and durability.

The Fourth construction method sees the board finished in 24/7 heat controlled environments to ensure curing times are at optimum levels to reach a finish unrivalled in Europe. The board is then sanded to a 240 dry sand finish ensuring that there is zero plastic lacquer on the board that can often look and feel horrible after a couple of months in the ocean.
