How to Use This Calculator

Enter your boat's PHRF rating — lower numbers indicate faster boats.
Input your elapsed (actual) race time in seconds.
Enter the course distance in nautical miles.
Read Corrected Time in seconds — this is your handicap-adjusted finishing time for the leaderboard.
Check Time Allowance (seconds per nm) to understand how much time advantage or disadvantage you give per nautical mile.
Review Performance vs Par (%) — values below 100% mean you beat the par standard for your rating.

How the result changes with Elapsed Time

PHRF Rating: Your boat's PHRF handicap rating in seconds per nautical mile. Lower numbers indicate faster boats. Check with your local PHRF authority.
Elapsed Time: Total elapsed time from start to finish in seconds. For example, 1h 30m = 5400 seconds.
Course Distance: Total distance of the race course in nautical miles, as measured by the race committee.

Corrected Time: Your finish time after applying the PHRF handicap. This is used to rank boats against each other.
Time Allowance: Total time adjustment based on your PHRF rating and course distance. Subtracted from elapsed time.
Time per Mile (Elapsed): Your average elapsed time per nautical mile. Useful for pacing and performance tracking.
Competitive Index: Performance relative to a par time of 600 sec/nm. Under 100% = better than par, over 100% = behind par.
