Rules & Ratings
As yacht racing became more prevalent, and yacht design more diverse, it was necessary to establish systems of measurements and time allowances due to the differences in boat design. Longer yachts are inherently faster than shorter ones; therefore, in the interests of fairness, in the 1820s a “primitive system of time allowance was introduced on the Solent.” Larger yachts were handicapped; but owners with the biggest vessels had a problem with the allowance system, for they preferred that crossing the finish line first, much as in foot and horse races, should suffice to win the contest. As a result both ratings and “one-design” competition were developed.
Ratings systems rely upon some formulaic analysis of usually very specific yacht-design parameters such as length, sail area, displacement, and hull shape. During the 1920s and through the 1970s the Cruising Club of America established a formula by which most racing/cruising boats were designed during that period. After its descendant, the mathematically complex International Offshore Rule (IOR) of the 1970s, contributed to much decreased seaworthiness (and even speed), the simpler Performance Handicap Racing Fleet (PHRF) system was adopted. The PHRF uses only proven performance characteristics, especially theoretical sailing speed, as a means to allow dissimilar yachts—typically crewed by friends and families at clubs rather than by professional crews—to race together. Most popular family-oriented cruising sailboats will have a rating filed with a local chapter of the PHRF.
The most prevalent handicap rating systems today are the ORC, ORR, IRC, and the PHRF.
One-design racing is conducted with classes of similar boats, all built—often via mass-production—to the same design, so that crew ability and tactical expertise are more likely to decide a race than boat type or even weather. Popular racing boats such as the J/22 and J/24, the Etchells, and the Star and New York 30 of Nathanael Herreshoff are examples of one-design boats.
In general, modern yacht-racing contests are conducted according to the Racing Rules of Sailing, first established in 1928. Though complex, the RRS are intended primarily simply ensure fairness and safety. The Rules are revised and updated every four years by the International Sailing Federation.

Famous quotes containing the word rules:
“Unfortunately, we cannot rely solely on employers seeing that it is in their self-interest to change the workplace. Since the benefits of family-friendly policies are long-term, they may not be immediately visible or quantifiable; companies tend to look for success in the bottom line. On a deeper level, we are asking those in power to change the rules by which they themselves succeeded and with which they identify.”
—Anne C. Weisberg (20th century)
