Dennis and Randy:
In Mass Bay, we're into our 2nd year with ORR-EZ. What you want to do is get
to the ORR-EZ web site and look over the certificate forms and what's needed to
rate your boat.........other than "supposedly measuring sails", the process is
relatively simple....
You wind up with a rating certificate that has essentially 6 separate ratings
dependent on course configuration and wind. AND whether you are sailing with a
spinnaker or not.......
This year they added a destination rating (point to point) as well as the W/L
courses and the Random leg courses, which is what we usually sail.
Don't get put off with the number of ratings...........I found that we used
the same rating most of last summer...........
The ratings are also provided for two types of scoring............Time on
Distance, and Time on Time...........in Mass Bay, we have been using TOT for
years.........the TOD has to many variables when you have to sail around
islands and such.
So, as an example...........my 38MKII used to rate 129 Racing and 132 Cruising
in PHRF. There was a 6 second "recreational handicap" bonus if you used a
working jib furler above deck.......
Typical of PHRF, there were other nuances that you could maneuver to advantage
or not...........Declare no spinnaker pole and get 9 seconds.......e.g.
ORR-EZ has none of that stuff.......it's basically a boat measurement, some
weight measurements, and several sail measurements...........they rate your
largest sail area ........
Impromptu's 2019 ratings are: wind at very light, light, medium,
heavy...........0.382, 0.603, 0.799, 0.919 Spinnaker
0.362, 0.577, 0.777, 0.904 non-spinnaker.........
So, all that matters is the elapsed time you sail the course in. You take that
elapsed time and multiply it by the factor for that race...........that
produces your corrected time........and that then compares to the other boats
in the fleet to determine the winner..............
We're spoiled here in New England for scoring..........there is a system called
Regattaman that was developed by a couple of our local guys several years ago
and that system has been adopted widely. They set up the course on the
committee boat, start the race and record the finish time for each
boat............all that happens live and by the time we get back to the dock,
the results are up with all that calculation completed and boats scored where
they placed.
If you're interested, you might log onto Regattaman.com and go to the calendar
page. That page shows all the racing in our region that is going on this year.
You can scroll down to the Spring Series Hingham Bay ORREZ (May 15th or so)
and see that we've sailed 4 races so far in the series, the last one will be on
the 19th...........when you click on results, you'll see the score sheet by
class. We sail 3 classes.
It's not uncommon for us to get over 20 boats in 3 classes on the course for
the Wednesday series.........
I hope you find this useful, let me know if you need addition info.
Best,
Ron C.

Subject: Re: Stus-List PHRF vs ORR-EZ
Hi Dennis,
No experience with ORR-EZ yet, but it looks like another good option by which
to score mixed fleet races (i.e. not one-design fleet races).
Last year Colorado Sail & Yacht Club experimented with National Handicap for
Cruisers (see https://www.rya.org.uk/racing/pages/nhc.aspx). We still used
PHRF as the official scoring system, but also scored the same races by NHC to
see the outcome of applying a different scoring system to the same race
results. We could do the same with ORR-EZ.
The proponents of this idea were looking for a scoring system that is more
“fair” than PHRF. I liken NHC to golf handicapping: your handicap changes with
every scorecard you turn in, conceptually. So it dynamically reflects
variability in weather conditions and crew performance, which a static PHRF
rating doesn’t. ORR-EZ appears to have some similar elements (observed
performance factor, configurablity per race course, etc.) which in my opinion
are valuable.
With a 30 MK I my results in my fleet are generally dependent on wind strength.
The stronger the wind, the better I place, all other things being equal. In
light air boats with less displacement beat me. It’s almost as if boats should
have different ratings for different wind speed ranges.
On a related note, my RSA is re-rating all boats in its region this year, and
Grenadine’s PHRF rating is likely to come out 12 seconds lower. But at least
one of my competitor’s ratings will stay the same - which exacerbates the above
problem, unless we have a really windy season. I think I’ll start a separate
thread on 30 MK I PHRF ratings, because I see 18 seconds variability across
RSAs.
Cheers,
Randy
