Ultra FreeWave SLS (SB, incl. fin)

In contrast to the industry-standard Shape3d program, our own exclusive 3D CAD software is based on math data-driven input. 

This allows us to cross-check the outcome using artificial intelligence to ensure maximum precision.

Apart from being much more accurate and faster, complex 3D design tasks such as our ground-breaking SYNCED CURVES CONCEPT would otherwise have been simply impossible to realize. 

The FULL CUSTOM SLS TECHNOLOGY is a full custom technology which is one hundred percent identical to high-end custom made boards.

Instead of using a mould to bring the EPS foam core into its final shape each EPS block gets CNC milled. This ensures maximum precision and saves weight. 

Same as with high-end custom board makers the major advantage lays in the processing. We call this SINGLE PROCESS TECHNOLOGY and it is the key to our industry-leading weight-strength ratio. Instead of combining working steps to save time and money every single step follows its individual process. So for example instead of joining the PVC sandwich with the EPS core in a single shot we vacuum-bag the top and bottom PVC shields with the EPS core separately. 

For all SLS boards we use our most sophisticated layup which consists of more than 50 individual parts and components.

The major difference compared to the FULL CUSTOM D/LAB TECHNOLOGY is the S-glass on the PVC sandwich for the SLS boards (like most wave boards on the market), while the D/LAB boards are equipped with a carbon-Innegra layer on the outside. Innegra is the best composite fibre to prevent dents. Dents caused by the mast touching the board (during catapults or when getting washed) are mainly an aesthetic issue. But if you want a board that stays dent-free, you should opt for the D/LAB version.

Last but not least even every single board size has an individual layup. That’s the final stage of individualization in construction.

Yet all of this is achieved without any sacrifice in durability since we always follow our core motto LIGHT DONE RIGHT.

Outline, rocker and rail shape are the 3 key elements that determine how a board feels and performs. In every rocker- and outline there are spots with more or less curvature. The same applies to the degree of rail curvature which changes considerably. To prevent the 3 curves from working "against" each other, the highest priority is to synchronize these curves. Means that in zones with an increased rocker curve, the outline curve is also increased plus the rails have an increased curvature and vice versa.

>> Increased outline curve, nose rocker and rail curvature around the mast track makes it easier to initiate the bottom turn (front foot initiated)

>> Increased outline curve, tail rocker and rail curvature behind the back strap for more radical top turns (back foot initiated)

To our knowledge this complex 3d task can only be performed by our own AI_BOARD_3D software. Testing this concept on existing boards the improvements to each board were so overwhelming that we incorporated this design feature into all 2026 boards.

The mini mast-track reduces the weight in the critical nose area. It also reduces the risk to misplace your mast base while still providing just the right amount of length adjustment for all riding styles and sail sizes.

High quality closed cell neoprene for maximum longevity. Only black Lycra coating guarantees maximum comfort as well as maximum durability. The strap features measurement markings to allow you to quickly set up and replicate your individual size. Board specific attachments:

> All World Cup boards come equipped with double-screw plugs to prevent any twist and ensuring the most direct connection to the board

> All other boards come equipped with single-screw plugs to allow a faster repositioning of the straps plus a more comfortable ride due to a certain "give"

NEW - Completely revised and unique design:

+ 20% less weight

+ Significantly reduced elongation for direct connection and to avoid slipping in too far with risk of injury

+ Improved preforming for quick and easy assembly

8-10mm thick duo density EVA (depending on the board type) provides best dampening comfort and control. The higher-density outer layer features our signature heat pressed diamond groove pattern that protects the EVA against abrasion and provides maximum grip level and connection to the board. We only select EVA colours which don't look dirty after use and will also resist fading after hours in the sun.

Reduced dome deck shape results in a more stable/balanced stance, especially in drift & ride conditions.

Very smooth and comfortable ride especially in chop thanks to constant V bottom shape with slight double concaves.

Parallel outline design provides low drag and boosts control. The wide tail ensures incredible early planing and upwind performance and improves the take off for jumping.

Medium rail diameter in the nose and center offer an ideal blend of performance and manoeuvrability. Thinned out rails towards the tail for maximum grip and control.

MINI-SPOCK SQUARE TAIL

The square outline combined with the thin yet boxy rail profile generates additional volume to push against. This generates extra pop for higher jumps.

Faster rocker line boosts planing power especially on the larger sizes.
