TIRED OF FREEWAVE BOARDS THAT FEEL FLAT AND FORGETTABLE — SAFE, BUT NEVER ALIVE UNDER YOUR FEET? THE ULTRA FREEWAVE 2.0 SLS WAS BUILT THE OTHER WAY ROUND: A POTENT NEW-SCHOOL FREESTYLE SHAPE FIRST, WAVE-TUNED SECOND. SO IT STAYS CRISP OFF THE PLANE, SHARP THROUGH THE TURN, AND WITH THE NEW TAIL IT TURNS TIGHTER AND MORE SPONTANEOUSLY THAN EVER. COMMIT TO THE RAIL AND IT FOLLOWS.

The Ultra FreeWave 2.0 SLS is a freewave windsurf board for intermediate to advanced riders. It covers bump and jump, side-on waves, and freestyle in a single versatile shape.

The Ultra FreeWave 2.0 freewave board was built around a potent new-school freestyle shape. Acceleration and pop come first. The board is then tuned to perform as a capable wave board in logo-high side-on waves. The outcome is a freewave windsurf board that never feels dull: crisp and responsive in a straight line, sharp and precise through the turn. The new tail outline sharpens that responsiveness even further, making the board turn tighter and more spontaneously. You commit to the rail, and it follows.

New for the 2.0: a domier deck around the footstrap area delivers noticeably improved riding comfort especially across longer sessions. Your feet stay planted and relaxed even in choppy, powered-up conditions, so you can focus on the next move instead of managing fatigue.

The convertible fin setup is one of the board's defining strengths. Run the tri-fin configuration to unlock serious wave performance in top and bottom turns. Switch to a single fin for freestyle focus and a more driven, exciting feel.

Built in Duotone's Full Custom SLS construction, the Ultra FreeWave 2.0 SLS uses S_GLASS+ reinforcement for a light, durable build that holds its shape over many seasons of hard use.

Available in six sizes from 74 to 119 litres, fin included.

Comparison Technology Levels

FULL CUSTOM D/LAB
(used on all D/LAB boards)

- For these boards we use our most high-tech raw materials (Carbon, Innegra/Kevlar) resulting in the lowest possible weights, crispest ride sensation and maximum dent-resistance.

FULL CUSTOM SLS
(used on all 2026 SLS boards)

- The SLS construction uses a lower Carbon content and the Innegra is replaced by our exclusive S_GLASS+. This results in a more attractive price level.
- These boards are approx. 300g heavier than the D/LAB boards.
- Due to the FULL CUSTOM CONSTRUCTION the SLS boards are stronger and lighter than comparable boards made in the usual semi custom construction.

FULL CUSTOM PVC-WOOD
(used on ULTRA FreeWave)

- Our most price attractive boards made in FULL CUSTOM CONSTRUCTION. These boards feature wood reinforcements that effectively dampen peak loads.

FINALLY LET'S TALK FINS

THE MATCHING FIN DESIGN HAS A SIMILAR IMPORTANCE TO THE BOARD PERFORMANCE AS THE RIGHT MAST FOR THE SAIL.
THAT'S WHY WE HAVE SPENT A TREMENDOUS TIME AND EFFORT INTO SETTING UP A TRULY UNIQUE FIN RANGE.


360° R&D
We don't just buy external stock fins. Instead one and the same team is now responsible for the board and fin development. This results in a perfectly matching unit lifting the board-fin performance to the next level.


FIN SPECIFIC TECHNOLOGIES
Instead of using one technology for all our fins we are using 3 different technologies according to the fin length and range of use:

- PREPREG FOR ALL LONGER FINS >> lighter than G10 and with adjustable flex due to the moulding process. 50% stronger than the usual RTM technology.

- G10 FOR ALL WAVE CENTER FINS >> indestructible

- INJECTION MOULDED CARBO_TECH FOR SHORT SIDE FINS >> guarantees necessary flex even on short fins

FINALLY LET'S TALK FINS


THE 2 MOST INFLUENTIAL FIN DESIGNERS
With Dani Aeberli and Kai Hopf, the two Windsurfing fin designers with the most experience are responsible for our new fin range.


EXCLUSIVE PRODUCTION
Setting up our own exclusive production was inevitable to take our fin performance to the next level. Every process is supervised on site by our own QC specialist Vasin Siritho to guarantee the highest level in quality and consistency.


FOR ALL THESE REASONS, WE HIGHLY RECOMMEND TO ONLY USE THE FINS SUPPLIED WITH THE BOARD.
THIS IS THE WAY - TO UNLEASH THE BOARD'S FULL POTENTIAL!
