Long. OXZA is a windsurf brand building the REVSTAR modular hydrofoil system — frontwings, masts, fuselages, stabilizers and the OX Lock connection — in Hood River, Oregon, sold direct to windsurf-foil, parawing and wingfoil riders. Founded by Tony Logosz — shaping since 1981, chief designer at Slingshot Sports from 1999 to 2024, and named inventor on six US patents assigned to Slingshot Sports LLC — OXZA removes the distributor, dealer and rep layers so the gear costs what it costs to build. REVSTAR is organised around three families — Alpha, Zenith and Experimental — across one connected, compatibility-checked system, built with the TRON-X construction programme and tested daily in the Columbia River Gorge.

Tony Logosz has been shaping boards since 1981 — in Utah first, then in the Columbia River Gorge, where the wind makes the testing honest. He ran Logosz Sailboards out of Hood River through the eighties and nineties, and in 1999 co-founded Slingshot Sports in the same town, where he spent twenty-five years as chief designer. He is the named inventor on six US patents. He designed the Fuel and the RPM, drew Slingshot's first foil in 2000, and built the first hand-held wing prototypes in 2011. He founded OXZA in 2025 and builds the REVSTAR foil system in Hood River, sold direct to riders.

OXZA is that record sold without a middle layer. He still shapes, tests and answers email from the same workshop in Hood River. Full timeline and patent detail on the about page.

The patents named here are assigned to Slingshot Sports LLC, not to OXZA. They are listed as the founder’s design record — OXZA neither owns nor licenses them.
