Handicap Example 30-min Race Force 1

The Portsmouth Yardstick is a handicapping method that povides a correction
so boats of differring inherent speeds can race evenly.

The formula is CT = (ET * 100)/HR.
                         where CT is corrected time, ET is elapsed time, and HR is handicap rating






If minute or second number is positive, they owe you time, if negative, you owe them time.
