The global demand for decentralized, low-carbon energy sources has renewed interest in wave energy converters (WECs). However, high capital costs and proprietary control systems limit adoption. This paper introduces SurfMill 95 Free —an open-source hardware and software specification for a 95 kW rated, oscillating water column (OWC) type WEC designed for near-shore deployment. The "Free" designation refers to both the freely available design files (CC BY-SA 4.0) and the passive, self-rectifying turbine control strategy that eliminates active pitch or hydraulic systems. We detail the hydrodynamic design, turbine aerodynamics, mooring analysis, and a novel "adaptive bypass valve" for storm survival. Numerical simulations show a capture width ratio of 0.38 at significant wave heights of 1.5–2.5 m, with a levelized cost of energy (LCOE) projected at $0.09/kWh—competitive with offshore wind. The paper concludes with a field validation plan for a 1:5 scale prototype. The "Free" designation refers to both the freely
