Sometimes we get asked "what are the handicap numbers for Lasers in mixed class racing". The numbers used by the Royal Yachting Association (GBR) in their Portsmouth Handicap system are:
| Laser | 1078 |
| Laser Radial | 1101 |
| Laser 4.7 | 1175 |
The numbers can be used for handicapping different Laser rigs within a mixed fleet. To use the numbers convert the elapsed time into seconds. Divide the elapsed time by the handicap number and multiply by 1000 to achieve a corrected time.
The handicap numbers work best on races around 100 minutes long. Further information on Portsmouth Numbers can be obtained on the internet at: www.rya.org.uk
Personal Handicaps
The Handicap Numbers take into account the difference in boat speed as a result of the different size rigs. The Handicap numbers take no account of an individual's ability. If the finishes are timed, a personal factor can be applied to the Handicap Number so that each person has a Personal Handicap Number.
The Handicap Numbers are based on race times. In a theoretical race where a Laser finished in 60 minutes a Laser Radial should finish in 61 minutes 17 seconds if all the sailors were the same standard and made the same mistakes!
A Personal Handicap can be introduced by adjusting the Handicap Numbers. For example changing the Laser Radial Handicap Number from 1101 to a Personal Handicap of 1102 would mean that in the same race the Personal Handicap would give an extra 4 seconds advantage on someone sailing a Laser Radial without a Personal Handicap.
Personal Handicaps can be fixed for a set number of races or adjusted in any number of ways based on the performance of the last race. For example if you win a race you are handicapped by 30 seconds in the next race. Second could be handicapped by 15 seconds etc. Similarly the last placed boat could be given a handicap advantage of 1 minute, second to last 30 seconds etc. A simple time or place penalty system like this can also be used instead of Handicap numbers. (See fleet handicaps)
It is best to keep race by race changes simple and restrict changes to a maximum of the first two and last places.
If you decide on a Personal Handicap System don’t forget someone has to manage it so KEEP IT SIMPLE.
