I went sailing with out the card in the gps. How do you get the data off the gps?
It involves the data logger doesn't it? can someone please help me out!!

I did what you suggested decrepit, and when you download any of the files in realspeed they come up as blank yet all the files are of a decent size.

Hey KA, you might be looking at the wrong date (as in today's data that was recorded when you were trying to download the data onto the card)

Later versions of Realspeed automatically split the file by date.

Easiest way to check is to throw it at www.ka72.com, this will automatically split by date as well...

Slightly harder way is to click on the "Track files" section on the LHS of realspeed, you should see your day's sailing in there. Click on the relevant date and hey presto.
