Windsurf sail Gaastra BOOST Blue 2026

The Boost 2026 has been designed as the go-to freewave sail, offering drive, stability, and smooth handling across a wide range of conditions. This new edition introduces the Continuous Radial Panel Layout, aligning the sail panels along natural load paths. This innovation reduces seam stress, improves durability, and enhances profile stability, resulting in a more direct and responsive feeling on the water. Its five-batten skeleton, supported by carbon radial tapes spreading from the clew, ensures that the profile stays locked in and reliable even in demanding wind conditions. At the same time, the Boost maintains a reactive and lively character, making it a capable tool for both blasting in chop and carving turns on waves.
