Partial The app shell and sport-specific scoring UI are standard, and wind and swell data can come from marine weather APIs. The proprietary ShoreSense model, which predicts how waves change over each of 2,500+ spots, needs domain science and local bathymetry data.
What it would actually take: The stack would combine a mobile or web frontend with ingestion of marine forecast APIs (for example Open-Meteo or Copernicus) and a spot database. The core difficulty is a nearshore wave transformation model that uses bathymetry, coastline, and local exposure, built by oceanographers or coastal engineers and validated against observations.
