STX iWINDSURF WS 280 RS – inflatable windsurf board

STX iWINDSURF WS 280 RS is a fully functional inflatable windsurf board designed for beginners and intermediate riders who expect high stability, comfortable handling, and solid performance. With dimensions of 280 × 86 × 15 cm and a volume of 280 liters, this model works very well for learning, family sessions, and first attempts at getting into planing.

A true inflatable windsurf board

The WS 280 RS is not a classic paddleboard, but a board designed specifically for windsurfing. It gives you the ability to ride more dynamically, maintain better control under sail, and work toward planing. It is a very good choice for riders who want to improve their technique and get more enjoyment out of active windsurfing.

Stability and performance for beginners and intermediates

The board is designed for riders who want equipment that is stable, predictable, and forgiving, while still allowing clear progression. The 86 cm width provides strong confidence on the water, while the compact length keeps the board easy to maneuver and more dynamic than larger, more recreational shapes.

FXL technology and reinforced rails

The construction is based on FXL (Fusion Double Layer X Light) technology. This is a light, woven, and welded construction where two PVC layers are fused together without glue. Combined with additional Double Layer Rails, it delivers very good stiffness, low weight, and strong resistance to deformation. This build gives the board performance that feels closer to a hard board while keeping the advantages of inflatable equipment.

Railsaver and 3 US-Box fins

The 2025 version features the Railsaver system, a specially shaped tail edge that improves water release and makes planing easier. Under the board there are 3 fins in the US-Box system – two rear fins and one central fin. This setup provides very good control, stability, and confident tracking while riding under sail.

Deck ready for active riding

The deck is finished with dual-color EVA foam using Honey Grip and Gator Grip textures, giving very good comfort and traction while positioning your feet. The board also comes with 4 adjustable neoprene footstraps, which can be mounted in different configurations depending on your riding style and experience level.

Compact and mobile windsurf setup

Despite its sporty character, the board remains easy to transport and store. The full set fits into a compact wheeled backpack measuring 90 × 42 × 25 cm, making it easy to travel with the gear without needing a roof rack. It is a very practical solution for riders who want a mobile windsurf setup.
