PHRF BC Formula:
| From: | To: |
The PHRF BC (Performance Handicap Racing Fleet British Columbia) Time Correction Factor is used to adjust race times based on a boat's handicap rating. It allows different boats to compete fairly by accounting for their relative speeds.
The calculator uses the PHRF BC formula:
Where:
Explanation: The formula calculates a correction factor that, when multiplied by a boat's elapsed time, produces a corrected time that can be compared across different boat classes.
Details: The Time Correction Factor is essential for fair competition in handicap sailing races. It allows boats of different sizes, designs, and performance characteristics to compete on equal terms by adjusting their actual race times based on their expected performance.
Tips: Enter your boat's PHRF rating in seconds per mile. The rating should be a positive number representing the number of seconds per mile your boat is expected to be slower than the benchmark boat.
Q1: What is PHRF rating?
A: PHRF rating is a handicap number assigned to sailboats that represents the number of seconds per mile the boat is expected to take longer to complete a course than the benchmark boat.
Q2: How is TCF used in racing?
A: Multiply your boat's elapsed time by the TCF to get your corrected time. The boat with the lowest corrected time wins.
Q3: What does a TCF less than 1 mean?
A: A TCF less than 1 means your boat is faster than the benchmark and your elapsed time will be reduced for scoring purposes.
Q4: What does a TCF greater than 1 mean?
A: A TCF greater than 1 means your boat is slower than the benchmark and your elapsed time will be increased for scoring purposes.
Q5: How often are PHRF ratings updated?
A: PHRF ratings are typically reviewed annually, but can be adjusted if a boat undergoes significant modifications or if performance data suggests the rating is inaccurate.
