I don't think you can join two .sbn files (the ones on the SD card), together in the GPS, but if you go to the logger and do a "save to card" you'll get the .sbp file, that has the last 7hrs on it. so if you've done over 7hrs that day you'll miss some data, but if you've done under 7hrs you'll have stuff from previous days that you'll have to separate out. probably almost as hard as joining two sessions together.

What software are you using? they all join sessions differently.

GpsResults and RealSpeed are programs that allow you to get a lot more out of your files, in your case joining 2 files would take less than 1 minute. You can also split your files, analize jybes etc. They cost a small fraction of the gps price and buying you support dedicated windsurfers that are providing useful tools for all of us.

Analysing my gybes is easy. If I come out of one dry it's a good one.

I will have a look at the other sites though.
