STX iWINDSURF WS 250 RS WindSUP Board + F2 Checker Rig

STX iWINDSURF WS 250 RS WindSUP Board

STX iWINDSURF WS 250 RS is a fully functional inflatable windsurf board designed for intermediate and ambitious riders. This is not a classic paddleboard or a typical recreational WindSUP – this model was created to deliver more dynamic riding, easier planing, and better control in stronger wind conditions.

A true inflatable windsurf board

WS 250 RS was created for riders who want more than calm cruising with a sail. Its compact length and sportier character make the board more responsive, more manoeuvrable, and more enjoyable during active sessions. It is a very good choice for riders who want to improve their technique and move into a more dynamic style of windsurfing.

Not a paddleboard, but real windsurf gear built for action

This model was designed as dedicated windsurfing equipment, not as an all-purpose SUP. Thanks to its construction and fin setup, the board handles tracking, sail power, and more performance-oriented use on the water much better. It is a strong option for riders who want to sail actively instead of just drifting recreationally.

Construction ready for more demanding conditions

The board is prepared for use with a rig and for more dynamic riding. The set includes as many as 4 neoprene adjustable windsurf footstraps, which improve board control and give more confidence during stronger sessions. This is a feature that clearly separates this model from standard inflatable WindSUP boards.

Three US-Box fins for better control

The model is equipped with two rear fins and one central fin, all in the US-Box system. This configuration improves stability, tracking, and the board’s behaviour when sailing with a rig. It is a setup created for more conscious, technical riding.

Compact format, strong potential

Despite its sporty character, the board remains easy to transport and store. Once packed, the whole set fits into a backpack measuring 90 × 42 × 25 cm, making it easy to carry the equipment and get it ready for a session. It is a very practical solution for riders who want a mobile windsurfing setup without giving up performance.
