Time on Time PURSUIT racing: This year handicap based racing in Mass Bay is going thru the biggest change in 35 years, the switch from PHRF based rating to a VPP(velocity prediction program) based rating system called ORRez. Exciting times! The GCR committee has decided to jump on the Change bandwagon and introduce a new pursuit race format based on the ORRez Time on Time ratings. As you probably know, traditional pursuit races set a race length in nautical miles. Then a boat’s Time on Distance rating is used to calculate their starting time. For example the difference in starting time for two boats is the difference between their ratings times the length of the course. If both boats sail to their rating they should arrive at the finish at the same time. The ORRez time on time ratings take into account not the length of the course in miles but the length of the course in time. To apply the ORRez time on time ratings to the GCR we will be setting the finish line after a predetermined length of time. This system has some nice advantages.
