PHRF TOD Calculator is a simple tool to calculate the corrected time of a sailboat that is racing under the PHRF time of distance handicap system. You enter the start time, the finish time, the boat's handicap and the course length. The app will then calculate the boat's allowance, her elapsed time and her corrected time. This can be used by race committees to generate finish times when boats are racing using a Time On Distance handicap system. It can also be used by racers to see how they finished compared to other boats before the race committee has completed their work.
