STX Rig PowerKid 5.0 Windsurf sail

The STX Rig PowerKid 5.0 windsurf sail sits in STX’s watersport range as a versatile board sail designed to capture wind efficiently and provide steady drive across a variety of conditions. Its mid-range “5.0” designation makes it a solid choice for sailors seeking balanced power and control without overcomplicating the rigging.

Constructed from ultralight monofilm with targeted Dacron reinforcement, the sail keeps overall weight down while adding strength where the load is highest. This blend helps the sail hold its shape in shifting winds, offers good responsiveness when you trim in and out, and stands up to frequent use without wearing out the corners or seams.

Monofilm is a clear polyester film that delivers stiffness and transparency, letting you see through the sail and maintain a consistent profile in gusts. Dacron is a durable woven polyester used to fortify high-stress areas against tearing. The included two-piece aluminium mast breaks down for easier transport and assembly, while still providing the necessary backbone to keep the sail stable in the wind.
