Have a look at:

http://www.opengate.se/vastervik/Content/a_cat_vm_frames.html

Only 18 boats classified in the first race.
Only 6 boats classified in the second race.
Only 5 boats classified both in the first and the second races.
All the others show no. 2 DNC and are already out of contention for the top places at the first days.
Most of them drove/flew thousand miles to get to Vestervik!!!
I can't imagine what's happened.
Any idea to explain these "strange" results?
