2027 Starboard iSonic Windsurf Board

Faster Where It Counts.

Built for uncompromising PWA-level slalom performance, the 2027 Starboard iSonic is engineered for explosive acceleration, pinpoint fin lift control, and maximum top-end speed.

For 2027, Starboard’s race development team focused on targeted tail and cutaway refinements to push average speeds even closer to peak velocity. Featuring revised double-step cutaways on the key iSONIC 60 and iSONIC 77 shapes, the 2027 iSonic reduces wetted surface drag around the fin box, giving riders superior trim stability, effortless power delivery through gusty conditions, and total confidence when pushing at the limit.

Whether you're lining up on a slalom racecourse or chasing personal GPS speed records, the 2027 iSonic ensures maximum speed with absolute control.

Key Race Innovations & Features

• Revised Tail Cutaways (iSONIC 60 & 77): Updated cutaway geometry minimizes wetted surface area around the fin, generating a slippery ride that elevates average speeds closer to maximum performance.

• Double-Step Cutaways: Refined step geometry promotes clean water release, boosting fin lift efficiency and straight-line tracking without pitching at high speed.

• Triangle Stabilizer: Enhances fin leverage and board stability in gusty winds, allowing you to lock in your trim and sail harder for longer.

• Flat Vee to Double Concave Bottom: Balances immediate acceleration out of jibes with smooth chop absorption along high-speed reaches.

• Extra Volume Midsection: Strategic volume placement supports early planing, maintains glide through lulls, and handles powerful cambered race sails effortlessly.

• Eco-Friendly Yulex Footstraps: Premium race straps built using FSC-certified, plant-based Yulex foam for maximum comfort and a reduced carbon footprint.
