The Race

We sailed the race Saturday, it was a 10 mile race. My boat came in
fith place but with the handicap we were fourth. I got beat out by an
E22, and 2 J24’s. The race was a lot of fun, it was so much fun for my
wife that she can’t wait to enter the next race. I still don’t
understand how the handy cap is equated, is it 240 seconds for each
NM? and then is it subtracted from your over all time in seconds?
Could someone please clarify.

10 NM race
2h 53m = 10380
240s * 10 nm = 2400
10380-2400=7980

Is that the correct way to figure out your corrected time?

Thanks,
Doug

Doug,

PHRF ratings are a form of
time-on-distance handicapping. In this system, each boat is given a
provisional rating that estimates how much longer it would take that boat to
sail one nautical mile compared to some baseline “imaginary” boat.

The ratings take into account (among other
things) waterline length, displacement, sail area, and keel depth.

Then, local PHRF organizations are
supposed to record finish times for sailed races and adjust the rating based on
actual performance in that area (ratings really vary based on local conditions*).

So, the way finish position is computed is
as follows:

Take the smallest PHRF hdcp time from all
competitors, and subtract that value from every competitor’s hdcp.
I’ll assume that the E22 was the
fasted rated boat in the fleet, so, E22 rates about 120 and you rate about 240
(only if you hoist your staysail – if not, then your PHRF should be about
255**). Hence, E22 gives you 120 seconds per mile, and gets zero
seconds per mile from everyone else.

Your race is 10 miles, so, your adjusted finish
time gets adjusted by subtracting 10*120 = 1200 seconds from your actual finish
time. Similarly, the J24 rates about 170, so it gives you 70 seconds per
mile.

  • The F21 is a great light
    air PHRF competitor, or when most of the course is off-wind. On the other hand,
    if wind is in the ideal sailing range (10 – 15), and much of the course
    is upwind, an F21 will find it very hard to finish in the top half of a good
    fleet of sloop-rigged boats.

** In the north-east, F21 rates 255 as a
cat rig, and 243 as a sloop rig

Best regards,

Joe,

I agree 100% with your observations about the different wind conditions.

Congratulations Doug!

You have brought honor and dignity to the Freedom-21 name.
