http://www.ussailing.org/portsmouth/tables08/tables08off-3.asp Is the link to Santana's ratings. The R rates at 84, the J24 is at 81.9 and the Merit 25 is at 83.3. The Yardstick is a widely used method of rating boats of different classes sailing the same courses and is used by clubs and fleets across the country. It is a time-on-time handicapping system and is derived from actual records of classes of boats with thoroughly documented ratings. Portsmouth Numbers are defined as the length of time boats would take to sail a common but unspecified distance. The formula is easy to use:
CT (Corrected Time) = ET (Elapsed Time) X 100 / HC (Handicap)
So the R gives up about 2 minuets to the J24, and 45 seconds to the Merit every 100 minuets. GO GET'EM. Bob
