Speed for Dummies
There are two types of timing. In normal sailing I use GPS, in Luderitz we use the video timing. For GPS windsurfing there is a huge following and all the info you could wish for on www.gps-speedsurfing.com it is certainly worth checking out. It has huge advantages, you can read the speed live straight from the display, which you wear on your arm whilst sailing. Later you can upload all the tracking info onto your computer to see where you peaked, where your fastest average was, how far you travelled, etc.. etc… It is also really great that you can instantly compare it to your friends which can introduce a bit of friendly competition every time you sail.
In Nambia we use the video timing which is just a fraction more accurate. To be honest the differences are very little, last year I compared my GPS run with the video timing on a number of occasions and the outcome was that there was only 0.01 knots difference. It’s a very small difference but still big enough for the record council who will only accept official world titles from video timing.
The only issue with this method is that it is expensive and not very flexible. You need 2 people to run it, one person is on the front reading speeds, whilst the other acts as the judge. They are quite expensive so you can’t really do that option everywhere and that is where GPS comes in use.
