Nationwide participation in the Dixie Portsmouth Numbers (D-PN) system culminated in the transfer of administrative responsibility to the United States Sailing Association, then the North American Yacht Racing Union, in 1973.
What does PY mean in sailing?
The Portsmouth Yardstick (PY) or Portsmouth handicap scheme is a term used for a number of related systems of empirical handicapping used primarily in small sailboat racing. The handicap is applied to the time taken to sail any course, and the handicaps can be used with widely differing types of sailboats.
How do you calculate corrected time?
Divide the “Elapsed Time” of each competitor in turn by the number of laps THEY have completed. Multiply each elapsed time by 1000 (one thousand). Divided each of these figures by the handicap to get the “corrected time”.
How is PHRF corrected time calculated?
Time on Time (TOT) also uses our PHRF ratings but calculates time corrections as follows: Corrected time = Elapsed time X 650/(550 + PHRF). For example, if your PHRF rating was 120 and it took you 63.5 minutes to finish the race, your corrected time would be 63.5 X 650/670 = 61.6 minutes.
What is corrected time in sailing?
After a race, each boat’s elapsed time (the time she has taken to complete the course) is multiplied by her TCC to calculate her corrected time (her race time making allowance for the characteristics of the boat). The boat with the shortest corrected time is the winner of the race.
What is the Portsmouth Yardstick used for?
The Portsmouth Yardstick System aims to handicap boats based on their relative performance against the other boats they race with. Handicaps are allocated and administered by clubs to suit their local factors such as boat type, wind trends and water type as well as enabling the club to evaluate crew skill factor.
How do you calculate race handicap?
How to Calculate a NASTAR Handicap
- PAR TIME = Pacesetter’s Time ÷ Pacesetter’s Handicap.
- Racer’s Handicap = Racer’s Time ÷ PAR TIME.
- Time required for a specific Handicap = desired Handicap x PAR TIME.
What is PHRF sailboat rating?
A. Performance Handicap Racing Fleet (PHRF) ratings are based on the speed potential of the boat, determined as far as possible on observations of previous racing experiences. It is the intent of PHRF handicapping that any well equipped, well maintained, and well sailed boat has a good chance of winning.
How are PHRF ratings calculated?
PHRF assigns a boat a rating, in s/M, which is multiplied by the length of the course and subtracted from the boat’s elapsed time to give corrected time. Ratings are assigned by a committee of the local racing authority, formed from representatives of the member clubs.
How do you score points in sailing?
The overall aim in Olympic sailing is to score as few points as possible. In this low-point scoring system, competitors/crews will record a point per position. For example, the winner(s) of each race will be awarded one (1) point, the second-placed competitor/crew will win two points, and so on.
How do you get points in sailing?
Points are awarded on the basis of a sailor’s or sailing team’s rank in each race. The first-place holder of a race gets one point, the second-placed sailor two and so forth. Hence, a lower number is better.
