Scratch Sheet

Calculate what it takes to beat the fleet

Select the desired class and then boat. Each boat's time correction factors are shown for the rating scheme announced. The table shows the minutes per hour of elapsed time a boat gains or loses in the rating compared to the selected boat. A negative value is owed to the target boat. In other words, that's how far ahead of them you must finish to win. All numbers are rounded to a few decimal points.
