Key Features
HIGHER AVERAGE SPEED (60 & 77)
Refined cutaway geometry reduces drag and wet surface, allowing the board to maintain speed closer to its maximum for longer periods.
IMPROVED FIN LIFT CONTROL
Updated cutaways stabilize fin behaviour, delivering greater confidence and consistency at high speed.
PROVEN TOP SLALOM BOARD
All other iSONIC sizes remain unchanged, continuing to deliver race-proven performance trusted by top-level riders.
REVISED CUTAWAYS FOR THE 60
Updated cutaways reduce wet surface around the fin, creating a more slippery ride with higher average speed closer to top speed and easier fin lift control.
NEW CUTAWAYS FOR THE 77
Inspired by the 2026 iSONIC 73, refined cutaways deliver explosive acceleration, excellent fin lift control, and outstanding average and top-end speed.
DOUBLE STEP CUTAWAYS
Refined step geometry promotes clean water release, increasing fin lift and efficiency while maintaining control at very high speeds.
TRIANGLE STABILIZER
The triangle stabilizer improves fin control and board stability, especially in gusty conditions, allowing riders to push harder with confidence.
SPEED-FOCUSED STANCE
Optimized rear strap positioning reduces drag and supports controlled fin lift, improving top speed stability and overall slalom performance.
FLAT VEE TO DOUBLE CONCAVE BOTTOM
The bottom shape balances early acceleration, control, and stability, delivering efficient speed across a wide range of slalom conditions.
EXTRA VOLUME MIDSECTION
Added volume through the midsection improves early planing, supports sustained momentum, and enhances stability under powerful sails.
MAST TRACK ADJUSTMENT RANGE
A refined mast track position allows precise tuning for different sail sizes, improving trim, acceleration, and control.
ECO-FRIENDLY FOOTSTRAPS
Made with FSC-certified, plant-based Yulex foam (85% natural rubber) for a reduced CO₂ footprint.

Constructions
CARBON REFLEX SANDWICH
The lightest and most reactive iSONIC construction, developed for maximum race performance.
Built around a fused EPS core, the Carbon Reflex Sandwich uses ultra-high density PVC in the standing area combined with full carbon laminates. The reflex carbon layup is tuned to return energy instantly under load, delivering explosive acceleration, precise fin lift control, and uncompromised stiffness at top speed. This construction is designed for riders who want the fastestACING race response, minimal flex loss, and absolute efficiency in slalom conditions.
WOOD CARBON SANDWICH
A performance-oriented construction balancing speed, control, and comfort over long sessions.
The Wood Carbon Sandwich combines carbon laminates with a wood sandwich layer in the standing area, working together with high-density PVC and glass reinforcements. This creates a smoother, more dampened ride while maintaining strong torsional rigidity and reliable fin drive. Compared to Carbon Reflex, the flex is more progressive, offering increased comfort, improved control in chop, and greater forgiveness during extended or demanding slalom races.
