What ChartedSails does
ChartedSails is a cloud-based sailing analytics platform that converts GPS data from competitive sailing devices into structured race, leg, maneuver, and performance analysis. Its core technology automatically ingests traces from virtually every major sailing GPS source — Garmin watches via Garmin Connect, Vakaros Atlas/Atlas 2/Edge, Velocitek ProStart/SpeedPuck, Sailmon, Expedition, Yacht Devices Voyage Recorder, NMEA/NMEA2000 logs, SignalK, and GPX/FIT/TCX/KML/UBX/CSV exports — then runs proprietary detection algorithms that identify races, split them into upwind and downwind legs, and call individual tacks and gybes with entry/exit speeds, VMG loss, and turn time. The platform also synchronizes onboard video (GoPro, iPhone, Insta360, DJI, drones) with GPS tracks by extracting embedded GPS timestamps, and stitches multi-boat tracks into a single synchronized fleet replay for clubs and coaching programs.
The product is delivered as a web application and an iOS native app (Android in development), with Stripe handling subscription billing. Revenue is generated through a freemium SaaS model: a permanently free tier providing GPS traces, speed data, and fleet replay, plus four paid annual tiers — Racer Pro ($349/year, individual), Team ($599/year, up to 6 boats), Club ($999/year, up to 12 boats), and Fleet ($1,799/year, up to 30 boats). Annual billing offers up to 50% savings versus monthly equivalents, and paid tiers progressively unlock leg breakdowns, maneuver analysis, VMG/polar comparisons, video sync, live coaching, Sailing Reports, and group licenses. An MCP (Model Context Protocol) endpoint at api.chartedsails.com/mcp allows AI assistants such as Claude and ChatGPT to query ChartedSails data directly.
ChartedSails is a privately held LLC incorporated in California and headquartered in San Mateo, founded around 2019 with a small team (1–10 employees). It serves three primary customer segments — competitive sailors, sailing coaches, and yacht clubs/class fleets — and is positioned as a modern, maintained replacement for the legacy RaceQs platform, capturing logos including America One Racing, J/70 and TP52 coaching programs, Waszp fleets, and Opti/ILCA youth circuits across the US and Europe.
