Getting the inside scoop on the new twin tips with Lars Moltrup – Motion

1) How do the rocker, flex and outline affect the board’s performance?

In general, these features have a great influence on the riding characteristics of the board and all work in relation to each other. Rocker, flex, and outline must all be adjusted and balanced to the target conditions you want the board to perform in. If you are looking for comfort in choppy conditions and soft landings, a higher rocker will be optimal, provided that the board has the right amount of flex.

If you want a board to plane out earlier, a low rocker board with narrow tips will work best. The low rocker will also need to have a lower value of flex so that it will not collapse on hard landings.

The outlines also play a big part in optimizing the board for the riding style and level of the rider.  Wider tips give you more radical pop and better flatwater freestyle performance, where narrower tips give you a more forgiving and comfortable riding experience.

To make it easier to understand and compare, we have started to define the flex and rocker with quantifiable values.  Stiffer boards have a lower flex value, for example, the dub = F32.  Softer boards have a higher value, for instance the Hero = F45.

To make the rockers easier to understand and compare, they have been defined in three stages of tangent radii creating a continuous curvature.  The radii is defined in the board specs and have different placements and sizes.  This gives the boards different riding characteristics.

Specifically to the Motion:

Medium rocker, low stiffness, and narrow tips make the board handle extremely well in chop. The rocker is highest in the stance area for handling chop, low in the center for early planing and almost flat in the tips for directional stability.  The medium rocker works well with the low flex and narrow tips to give a forgiving, comfortable ride. The Motion has slightly extra length to it, which also makes it the twin tip of choice for people who want to go play around in the waves.

 

2) How does the bottom and deck shaping contribute to the performance?

The different contours and features on the bottom of the boards give various characteristics to the board.  When designing the deck of the boards, it is overall a matter of reducing weight, but also very much an efficient way to stiffen the board up with minimal use of materials.   The tip shapes provides an I-beam effect which gives a much stiffer tip than if it was a flat or single concave.

Specifically to the Motion:

The triple concave 3D bottom gives the Motion incredible drive, control and soft landings. The beveled tunnel edges disperse water on landings and increase tracking, which makes the ride smooth and adds to the shock absorption on landings.

 

3) What is the philosophy behind the construction?

The design objective is focused on making the boards as light as possible. For this reason, we are utilizing high tensile gradated laminates, which means that the largest amount of fiberglass is at the stance area and in-between.  This also means we can reduce the amount of material applied to the tips to save where less reinforcement is needed.

All boards also have impact reinforcement zones, which are fiberglass patches that disperse impact forces throughout the board, thus increasing durability.

 

4) What does the rail shape do for the board?

Throughout the twin tip line, all the boards have step rails.  This concept was implemented to reduce weight by reducing the overall wood core volume and increase grip on the water.

 

5) What is Flex Torsion Control?

The Flex Torsion Control is added on the high performance boards to increase stiffness in both the axial and torsional axis, specifically in the area where it is needed.  Without adding excess weight to the board, the Flex Torsion Control gives the board a better response and a more dynamic ride.

 

6) How does fin positioning affect the board?

For the new twin tip line, we have found the optimal position for the fins through vigorous testing.  Testing criteria has been upwind ability, edging, comfort and release from the water.

Specifically to the Motion:

The angling of the fins is related to the bottom shaping and desired characteristics of the board. On the Motion, the fins have been angled 4 degrees in order to improve the grip and upwind ability.
