IRC

IRC

IRC is a rating rule to handicap different designs of keelboats allowing them to race together. Each boat’s rating (her ‘handicap’) is calculated using measurements of the boat; her length, weight, draft, sail area, etc. The resulting time corrector, the boat’s ‘TCC’, is her handicap. 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.
