Dynamic GPS Handicapping

 

Using the wealth of data that GPS tracking data generates SailRacer has been working on a system that generates dynamic handicaps that are context sensitive to the conditions experienced in individual races. The challenge for traditional handicapping methods is that the handicaps for each class are an average covering all conditions experienced, which could be a drifter to survival conditions. This was clearly illustrated at the 2017 Draycote Dash, which in light conditions saw the faster boats struggle to get into the top ten, despite being sailed by some top sailors eg the Fireball of Ian Dobson and Richard Wagstaff both class Champions and regular winners over the SailJuice Winter Series, who for the average lap races scored on corrected time : 12, 21, 21 and 34 as they struggled to sail to the handicap of 948.Using the methodology outlined below, Ian Dobson would see a score line of 2,3,5 and 8 (total 18 compared to 88).
