Reid Smith
Founder & Creator — SailVision

"Every competitive sailor deserves the tools the top teams have. SailVision exists to close that gap — professional data, coaching, and analysis for every sailor on every body of water."

Reid Smith built SailVision entirely from the ground up — the physics engine, live NOAA weather integration, polar interpolation system, and every screen of the experience. A sailor himself, Reid understood the gap between the coaching tools available to elite teams and what the rest of the community could access. SailVision is his answer.
