COMPETITION SLALOM BOARD
Full Control, Full Speed !
Control and top speed – that’s what it takes to reach the podium. JP’s five Slalom boards are built for blasting at PWA competition speed, rounding jibes at full speed, and maintaining precise control across a wide range of conditions. Their stability also benefits lighter riders, keeping them in control even when fully overpowered, while allowing rapid acceleration to top speed. The new SL 72 pushes performance even further: optimized hull aerodynamics, refined rail and deck shapes, and a higher water position let it slice through chop effortlessly, accelerate faster, and stay rock-solid through the most demanding jibes. S-TEC construction combines a striking look with reduced weight and enhanced stiffness, enabling earlier planing, easier handling, and higher top-end speed. Whether chasing the podium or pushing personal limits, the SL delivers the perfect balance of power, responsiveness, and confidence.
S-TEC
The S-TEC construction used across JP’s race boards delivers a combination of very low weight and high stiffness. This is achieved through a carefully considered design:
* No paint
* Anti-slip coating limited to the standing areas
* Compact pads with minimal EVA and glue
* A refined custom lamination process with fibres prepared and laminated separately
This construction provides early planing, easy handling, and maximum performance on the water.
The New 72:
In the highly competitive SL world we are constantly working to improve our range, the SL 72 has been upgraded to significantly increase overall speed by trimming the board to a higher water position, reducing wetted surface and drag. This allows riders to go faster while maintaining greater stability and control in rough conditions.
During the development, the hull’s aerodynamics were optimized, particularly in the nose area. A redesigned rail and deck shape in front of the mast base ensures smooth airflow over the deck, keeping the board stable and efficient even in challenging conditions. Towards the tail, the outline and deck shape were smoothed, especially around the back footstrap, offering a more connected feel and a comfortable stance.
These updates also improve gybing ability, giving more control when entering at high speed and exiting the turn, making riders more competitive not only in straight-line speed but also around the mark.
Key features retained from the rest of the range include:
- Smooth scoop rocker line and transforming V-flow – strongly pronounced in front of the mast base, tapering down between the foot straps, then opening towards the tail. This reduces drag, supports a high and loose water position, and facilitates control during gybes to maintain speed.
- High apex rail shape – generates lift for early planing, acceleration, and stability during gybes.
- Tail tuck line with double stepped cutout – maximizes control, release, and speed.
- Thoughtful footstrap positioning – enables efficient power distribution and easy strap entry/exit for gybes.
The general concept of our SLALOM line:
When designing and fine tuning this line, our focus is to increase the average speed across the racecourse, 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 to provide steady fin pressure for permanent power and top speed. The Slalom 62.5, 66.72 amd 76 feature Double Step Cut-Outs, meaning their two cut-outs have different heights.
From the mid-section of the board towards the nose we lifted the apex point of the rail. That way we gained some volume in the rail which helps exiting jibes with speed.
Beside the aerodynamic deck shape, we 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.
Six core design elements guarantee the perfect set-up for PWA racing:
DUAL TAIL OUTLINES – individually adjusted to each board size. The Cut-Out configuration reduces the outline width and the wetted surface of the bottom for less drag and higher speeds. The deck outline above the cut-outs is wider which results in a further outboard rear strap position: The rider can load more power onto the fin for more control and speed. The Double Step Cut-Outs of the 62.5 and 76 are parts of this individual shape adjustment.
TRANSFORMING VEE FLOW along the bottom – the Vee is strongly pronounced in front of the mast base, decreasing between the foot straps and opening again towards the tail. Thus, the board rides high and loose, ironing out all the chop. The transforming V results in a curvy rail line which makes jibing smoother and helps to exit the turn at full speed.
COMPACT CONCEPT – The parallel outline in the mid-section of the short board maximizes the planing surface at the mast base, lifting the boards onto the plane instantly.
THIN PROFILE – in the nose area reduces drag since this is the part which is affected most by the wind. This, in combination with a aerodynamic deck, means we managed to keep the swing weight centred for great top end control.
DECK SHAPES – Stance
A tiny but essential advantage: The comfortable and ergonomic deck shape guarantees a relaxed stance, allowing the rider to focus on going faster.
DECK SHAPES – Efficiency
The board features the proven aerodynamic deck reducing swing weight and now comes with an additional recess for the deck box, dropping the pivot point of the mast base. As a result, the sail foot seals the gap between the board and sail providing ultimate efficiency as well as additional control when pushing the limits and during the jibe.
The boards feature a standard Deep Tuttle box and are not approved for foiling.
