Duotone ULTRA FEEWAVE 2.0 SLS Board
The Ultra FreeWave 2.0 SLS is a freewave windsurf board for advanced to expert 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 powerful new-school freestyle shape. Acceleration and pop come first. The board is then tuned to perform as a capable wave board in head-high Side-On waves. The result is a freewave windsurf board that never feels boring: crisp and responsive in a straight line, sharp and precise through turns. The new tail outline further enhances this responsiveness, allowing the board to turn tighter and more spontaneously. You lean into the edge, and it follows you immediately.
New in the 2.0 version: A more pronounced dome deck around the footstrap area delivers noticeably improved riding comfort, especially during longer sessions. Your feet stay stable and relaxed, even in choppy water and under heavy pressure, so you can focus on your next move instead of fighting fatigue.
The convertible Fins setup is one of the board’s defining strengths. Ride the tri-fin configuration for serious wave performance in top and bottom turns. Switch to a single fin for a freestyle focus and a more direct, exciting feel.
Built using Duotone’s Full Custom SLS construction, the Ultra FreeWave 2.0 SLS features S_GLASS+ reinforcement for a lightweight, durable board that holds its shape through many years of heavy use.
Available in six sizes from 74 to 119 liters, fin included.
