Time predictions need a rating for each boat -- something that tells the app how fast it sails at a given wind angle and speed. The app supports six rating types, each with its own tab on the Assign Boats page and its own tab on the Regatta and Course Analysis page's boat list. You may specify per organization which of these are included in your analysis page.
- ORC -- an ORC certificate, looked up directly from ORC's own database. Full VPP (velocity prediction) data. The organization configuration page lets you pick which of the many countries ORC supports are included.
- ORR-EZ, ORR-Offshore, and ORR-Short -- the three ORR certificate variants, uploaded as a certificate file.
- EXP -- a generic, boat-type polar (an Expedition-format file covering a class of boat rather than one individually-certified hull). Use this for a boat with no certificate of its own, as long as its type is close enough to a listed boat type to give a usable estimate.
- NC-PHRF -- a PHRF rating. PHRF boats are scored by a handicap number, not VPP data, so their predicted times come from a rating formula instead of a certificate.
A boat only needs one rating to show up in predictions, but nothing stops it from having more than one -- for example an ORC certificate and a PHRF rating -- if you want to compare both.
Adding a new boat
Open the Assign Boats page for your regatta and click the tab matching the rating you're adding. ORC boats are looked up by certificate number directly on that tab. For ORR, ORR-EZ, ORR-Offshore, ORR-Short, or PHRF, use the + Add an ORR / ORR-Ez boat or + Add a PHRF boat link below the tabs, which opens a short import form; once submitted, the boat appears in its tab's list. EXP boats come from a fixed list of boat-type polars already on file -- pick the closest matching type from the EXP tab rather than adding a new one.
Once a boat is added, it's available regatta-wide: use its Class dropdown on this same page to put it in a division (see Divisions and Classes), and it'll appear in its rating tab on the Regatta and Course Analysis page ready to select for predictions.
