Three major US yacht clubs, the
Chicago
Yacht Club , Cruising
Club of America and Transpacific
Yacht Club, joined forces in the Fall of 2004 in an alliance called
the Offshore Racing Association (ORA). ORA was formed to promote and support
the use of VPP-based handicapping and has undertaken the task of developing
a new measurement-based rating rule that provides the fairest handicapping
possible. This new rule has been given the name Offshore Racing Rule (ORR)
and is targeted for use starting with the 2006 racing season. The Offshore
Racing Rule (ORR) is administered by the Offshore Racing Association (ORA).
ORA and US SAILING, the national authority for sailing in the United States,
are both responsible for its implementation.
The ORR predicts relative time allowances between boats to permit boats
of different sizes, types and ages to compete with the fairest ratings possible.
The ORR is an objective rule. Its ratings are based on full measurement
of all the speed-related features of sailboats and on a Velocity Prediction
Program (VPP) that calculates the speed potential of each boat at any combination
of wind speed and course direction. The VPP is a set of algorithms developed
through systematic research that use fundamental scientific methods.
The ORR Rulebook provides details about measurement, restrictions, ratings
and everything else required to race under the ORR. Owners, sailors, designers,
sail-makers and builders should consult the rulebook to prepare and race
their boats. This Quick Start Guide provides an overview to help owners
understand what they need to do to race under ORR. |
