PHRF of Lake Ontario

In December 1979, 12 yacht clubs along the south shore of Lake Ontario
gathered to discuss area wide PHRF ratings to facilitate their inter-club racing.
Thus laying the foundations of PHRF Lake Ontario.

Since that time, PHRF-LO has grown to include over 60 yacht clubs, 100 Club
Handicappers and over 1500 active certificate holders.

Over the past 2 decades, hundreds of dedicated volunteers have spent many hours
of their own time developing the PHRF-LO system and have helped issue yacht racing handicaps
to over 4000 owners around the lake.

With sister organizations throughout Canada and the United States, PHRF
has held its place as one of the top yacht racing handicap systems in North America.

New for 2009

In November of 2008, the Central Council of Handicappers for PHRF-LO voted in favour of adjusting the Q.Factor in our Time on Time formula to .008 from .045.

This was as a result of an in depth analysis of over 3500 races for the last 5 years by our Technical Advisory Committee.

As a result, our formula was adjusted slightly to accomodate that change. Below is the modified version of the original formula.

Q = .008
S = Scratch Boat = ASP 177
R = (8.36 x 10⁶) ÷ ((ASP + 378.3)²)
RS = (8.36 x 10⁶) ÷ ((177 + 378.3)²)
TOT = ((1 ÷ √RS + Q) ÷ ((1 ÷ √R) +Q))
or TOT = (578.431 ÷ (ASP + 401.431))

Your new A & B values are:

A = 578.431
B = 401.431
