How do I get my polar from my ORC certificate?

If your boat is ORC rated, its polar already exists: it is in the certificate. NavimetriX fetches it for you.

  1. My boat tab, tap the selected polar.
  2. Open the ORC tab.
  3. Type whatever you know: a sail number, a boat name, or a class name — "Sun Fast 3200" returns every rated Sun Fast 3200.
  4. Pick the certificate from the list and import.
ORC tab: search by class

What you will see in the list

One boat can hold several certificates, and they are not equivalent: full crew, double-handed, non-spinnaker. The family is spelled out so you take the right one.

Beyond 24 knots

An ORC certificate stops at 24 knots of wind and starts at 4. A checkbox, on by default, extends the polar to 60 knots.

This is not blind extrapolation: the app looks in its library for the boats whose speeds most resemble yours over the shared range, then applies their heavy-weather behaviour. The generated columns are marked as extrapolated and stay editable.

The certificate's provenance — sail number, family, issue date, crew weight — is kept and shown with the polar.
