Ce que couvre cette vidéo

A Norwegian programmer named Jostein Hellerud built a free hobby website that pulls data from the ORC database and presents sailboat rating certificates in a searchable, comparable format.0:08 The site lets sailors look up any registered boat by sail number, compare ORC polar speed data across wind angles and wind speeds, and run informal head-to-head comparisons between boats — what Hellerud calls a "mini-regatta."0:33 ORC certificates contain theoretical boat speeds for every wind angle and wind speed, data that most sailors ignore but that reveals, for example, whether to sail lower on a run in light air, when to plane, and how high to point upwind as breeze builds.1:01 The site surfaces those numbers as graphs and tables.1:34 Hellerud notes the ORC database has data-quality inconsistencies — identical boat models sometimes show different mast heights, beam, or displacement — and recommends cross-checking the site's output against the original paper certificate, which includes a hull drawing that can visually expose measurement errors.8:40 The site is free to use. The practical takeaway: ORC polar data already tells a sailor how fast their boat should go in any condition; the challenge is sailing to that number.
