Exactly a decade ago, Patrik put his first formula board into production and today he is the only shaper, who has supported this discipline by continuing to design, shape and register a formula design at every possible registration date. This substantial period of continued development has allowed Patrik to maintain a race winning formula board. Whilst the revolutionary invert-V feature has changed the way the new FV3 rides, it has also opened up new doors for Patrik to experiment with new shapes, which all equates to a noticeable leap forward in performance this year. Patrik: “The formula design was my entry ticket into the shaping scene and today I’m still fascinated by this unique discipline. Recently someone reminded me that ever since my very first production formula design, I remain the only shaper not to have missed out on registering a formula board since. It makes me proud to know that many other brands have had to stop with their formula designs or had to change shaper in order to keep up! I hope you enjoy reading about the new FV3 – I’m sure you’d enjoy riding this new evolution of PATRIK Formula design even more!”
PATRIK formula: Evolution with a true performance upgrade!
It is not an easy task explaining how microscopic changes in shape can affect performance. However, it is not in our DNA to just say that our board is the best on the market, points better upwind, is faster and easier, lighter, stronger, etc., as this would just be the standard marketing text from any brand. We would rather spend some time trying to explain in detail what we have experienced in the past and how our continued development has led us to the new board shape. So, here we go..
History of the new bottom shape concept “Invert V”: In 2005 Patrik shaped some single concave concepts for formula and speed boards. The performance was very good and the shape worked best with a tail kick of 1-1.5 mm and some extra side kick (rail rocker) on the formula of also 1-1.5 mm. Unfortunately, the tail and the side kick measurements are very sensitive and if the kick was off by just 0.5 mm the boards were either too sticky and slow or too loose and hard to control. It was clear that this shape concept worked extremely well for custom boards where the shaper can finish the board perfectly, and even rework the perfect tail and side kick after the first sailing session, but it was not possible to realize this concept for production boards due to the factory tolerances and measuring methods.
The main difference and advantage of the Invert-V is that the water flows along the Invert-V surface towards the centre of the bottom shape and concentrates in the middle of the board to give more lift. This hydrofoil effect means that the board rides higher above the water and glides freely over the chop. Due to this effect it was possible to change many other details of the shape to improve overall performance without losing the existing performance benefits.
The old rocker line did not work with the Invert-V concept, because it was unstable across the axle, so we replaced it with the new rocker line from the Slalom 128 to harmonize with this concept.
Due to the hydro effect of the Invert-V concept the board feels more free. This enabled us to extend and straighten the tail outline to improve the rail power under the back strap so the rider can keep pushing the upwind angle at lower speeds. This small detail really helps right at the start of a race and immediately after tacking.
With the new board riding higher on the water we inverted the deck shape to lower the mast track position and keep the connection point of the rig at the same level as the previous model. This helps to keep the board controllable and makes the shape a bit stiffer at the same time. The deck shape at the downwind strap is angled and allows for a more comfortable stance.
The above combination of changes made for a steady riding position, so we were able to shape the back foot rail a bit more boxy to allow the rider to push harder going upwind. The back foot rail size/width can be tuned with the adjustable wing setup. The combination of increasing V and the 5cm wide bevel mean the actual rail is thinner, but higher to keep it off the water as long as possible.
Early planing, acceleration and top speed are the most important performance aspects of this shape whilst being lightweight and stiff are the main requirements of the construction. It can prove difficult to build such a big board light because every reinforcement adds weight. However, smart combinations of layering and the positioning of reinforcements ensure that the board withstands all the heavy pressure of pushing this board up and downwind, whilst remaining light. Due to the new board riding higher on the water and impacting less against the chop, we were able to increase the stiffness by applying the Invert-V shape throughout the whole deck and with a full Carbon Biax 45°-45° we reduced the torsion at the same time. The tail shape Invert-V on the bottom runs into a very strong Positive-V shape under the mast track which also helps stiffen the board and this in combination with a full Carbon Unidirectional as a final layer proved the best combination of shape and construction during testing.
