PHRF RATINGS and RACE COURSES

PHRF Ratings are based on speed potential and performance with "seconds per mile" (Time on Distance) used to express the Ratings. Increments of performance used for Ratings are normally three (3) seconds per mile.

1.1 PHRF SEF uses a system of THREE RATINGS to more accurately reflect the performance potential of boats. The Ratings are designated as the "BUOY COURSE RATING" (W/L), the "RANDOM LEG COURSE RATING" (R/L), and the "OFFWIND COURSE RATING" (O/W).

a. The BUOY Rating is assigned to windward/leeward courses with no reaching legs. The windward leg is no longer than five (5) nautical miles. The windward & leeward marks are capable of being moved to maintain a true windward/leeward course.

b. The RLC Rating is assigned to courses that could require "beating", "reaching", and "running". Marks of the course may be selected without consideration of actual wind direction.

c. The OWC Rating is assigned to courses that, under normal conditions, are expected to have at least 2/3 of the distance be a "reach" or a "run". This rating will be used on all races where any leg exceeds 20 nm.

2. Only PHRF SEF may issue Ratings to be used in a PHRF SEF race.

2.1 The PHRF SEF Board of Directors shall advise yacht clubs and other race organizers regarding the appropriate Rating type (Buoy, Random Leg, or Offwind) to be used in PHRF races.
