According to JP's shaper Werner Gnigler, the key shape feature for these high-performance boards is the changing V-flow along the smooth scoop rocker line. The V is strongly pronounced in front of the mast base, tapers down near the foot straps and opens up again towards the tail. This reduces drag, improves efficiency, and supports a high and loose water position while facilitating control during jibes to maintain speed through each turn.

The general concept of the SLALOM line:

When designing and fine tuning this line, JP's focus is to increase the average speed across the race course, paying special attention to jibing where some of the biggest gains can be made during a race. Here, the target is to maintain speed throughout the turn and to exit faster.

The shapes offer a great, locked, and stable riding position. Far less effort is required to reach and maintain top speed and all of them provide great early planing power and a wide range of use. The tails of these boards are wide and provide lots of leverage towards the fin, resulting in more power and control.

The smooth deck shape guarantees a super comfortable stance. The rider preserves energy to push his limits on longer runs. All sizes feature an additional pad wedge between the tail straps providing a more connected feel. Each board size features its individual tail Cut-Out configuration in the bottom to find the perfect mix of release and lengthy rail line for control, for example, the first Cut-Outs of the bigger boards start much further forward and the curve of the Cut-Outs increases towards the tail.

The target is always efficient water release as well as an even water flow around the fin in order to provide steady fin pressure for permanent power and top speed. The Slalom 62.5 and the new 76 feature Double Step Cut-Outs, meaning their two cut-outs have different heights. From the mid-section of the board towards the nose JP lifted the apex point of the rail. That way producer gained some volume in the rail which helps exiting jibes with speed.

Beside the concave deck shape JP used an additional recess for the deck box. The pivot point of the mast base drops and provides additional control when pushing the limits and during the jibe. “Close the gap”: The lowered sail foot creates the most efficient airflow.

The design concept of the new SL 66 is more similar to that of the SL 62.5. On the one hand, this new shape for medium winds is for those lighter riders for whom the SL 72 feels too big. On the other, it is an medium to high wind board for heavyweights who prefer a little more width and volume than they can find in the small 62.5. The slightly larger size makes planing and sailing easier overall. Whether you're racing or just enjoying an exciting ride, both new boards deliver goosebump-inducing speed for everyone. The new 76 and 66 Slalom windsurfing in medium to light winds is simply a great, thrilling experience, and the 125 L board is built for exactly that. The SL 76 feels lighter and more playful than the big, wide SL 85 you would need for the lightest of winds.
