Simplifying weather-routed scoring for race organisers and scorers.

The Offshore Racing Congress presents RaceFlow 2.0, an updated web platform that brings ORC’s Weather-Routed Scoring (WRS) directly to race committees and scoring officers.

Offshore and coastal races rarely see steady conditions from start to finish. When the wind shifts or dies overnight, fixed handicap numbers often favour one end of the fleet over another. Weather-Routed Scoring solves this by simulating how each yacht sails the course through forecast weather, producing custom Time Correction Factors (TCFs) based on the actual conditions boats are expected to encounter.

RaceFlow 2.0 pairs the ORC Velocity Prediction Program (VPP) and certificate database with the PredictWind routing engine, packing the entire workflow into a clean browser interface built specifically for event management.

Built for the Scoring Desk and Race Committee

RaceFlow 2.0 focuses directly on simplifying and accelerating the workflow before, during, and after a race:

  • Direct ORC Rating Data Integration
    One-click boat selection and automatic fleet sync with the global ORC certificate database, as well as import from existing ORC Scorer files.

  • Interactive Visual Course & Exclusion Zone Designer
    Intuitive map-based waypoint management and visual polygon geofencing to steer fleets safely around TSS zones, shallow waters, and hazards.

  • Single-Click Scoring Factors & Exports:
    Automatic generation of Time-on-Time (TOT) and Time-on-Distance (TOD) allowances, exportable directly to ORC Scorer XML, CSV, and standalone interactive HTML packages.

  • Wind & Race Breakdown
    Duration-weighted wind distributions (TWS / TWA), upwind/reaching/downwind breakdowns, and correlation scatter plots to validate scoring models against fleet performance and see how the weather affected different boats.

  • Visual Fleet Animation & Scratch Sheets
    Real-time speed heatmaps, animated playback showing how the race unfolds, and print-ready scratch sheets for the race committee board.

Availability

RaceFlow is available as a free service for race organisers. The ORC technical staff assists with initial event setup, allocates all necessary routing credits, and provides help and support.

Organisers planning coastal or offshore events can log in to raceflow.orc.org using their Sailor Services credentials, and apply directly through the platform or review the documentation.
