Scoring rules reference

These are application calculation references. An event’s notice of race, sailing instructions, and protest decisions control its published result.

PHRF time on time

CT=ET×TCF=ET×AB+PHRFCT = ET \times TCF = ET \times \frac{A}{B + PHRF}
TCF=AB+PHRFTCF = \frac{A}{B + PHRF}

The factor uses the event’s A and B coefficients; the event chooses those values.

PHRF time on distance

CT=ET(PHRF×D)CT = ET - (PHRF \times D)
Allowance=PHRF×D\text{Allowance} = PHRF \times D

D is course distance in nautical miles. Use the published course and method for the event.

IRC and ORC

CT=ET×TCCCT = ET \times TCC
CT=ET(PLT×D)CT = ET - (PLT \times D)

Use the certificate and method selected for the race. A displayed calculation is not a substitute for event instructions.

Score codes

The table lists application defaults. A hearing, sailing instruction, or organiser decision can set the applicable score.
